Scientists have developed a new technique that can repair and even regenerate heart muscle cells after a heart attack (or myocardial infarction).

While it has only been tested on mice so far, if it works the same in humans it could potentially be a life-saving treatment for people who have suffered a heart attack.

The technique uses a synthetic messenger ribonucleic acid (mRNA).mRNA creates a 'blueprint' of DNA sequences that the body then uses to build the proteins that form and regulate our cells.By tweaking the mRNA, scientists can deliver different instructions for different biological processes.

Here, the edited instructions promote the replication of heart muscle cells (cardiomyocytes) via two so-called mutated transcription factors, Stemin and YAP5SA.

Essentially, the idea is to make heart muscle cells, which have very little ability to regenerate, act more like stem cells, which can be turned into various other types of specialized cells by the body.

The difference made by the mRNA treatment after four weeks. (The Journal of Cardiovascular Aging)

"No one has been able to do this to this extent and we think it could become a possible treatment for humans," says biologist Robert Schwartz, from the University of Houston in Texas.

Less than 1 percent of adult cardiac muscle cells can regenerate the cardiomyocytes we have when we die are mostly the same ones we've had since the first month of life and that means heart attacks and heart disease can leave the heart in a permanently fragile state.

In experiments in both tissue culture dishes and in living mice, Stemin was shown to turn on stem cell-like properties in the cardiomyocytes, while YAP5SA promoted organ growth and replication. The process has been described as a "game-changer" by the team.

The in vivostudy involving living mice affected by damaged hearts showed myocyte nuclei replicating by at least 15-fold in the 24 hours after the injections of the mutated transcription factors, Stemin and YAP5SA.

"When both transcription factors were injected into infarcted adult mouse hearts, the results were stunning," says Schwartz.

"The lab found cardiac myocytes multiplied quickly within a day, while hearts over the next month were repaired to near normal cardiac pumping function with little scarring."

The synthetic mRNA added to the cells disappeared in a few days, just as the mRNA produced in our bodies does, the researchers report. This gives the new technique an advantage over gene therapy processes that cannot be easily stopped or removed once they're underway.

It still remains to be seen whether the approach can be translated successfully into humans and many more years of research will be required to get this into a working treatment but the team behind the research is confident.

Work continues to understand more about heart disease and heart injury, andhow the body respondsin its aftermath. Studying cardiovascular health remains a priority for scientists, with heart disease currentlythe leading cause of deathin the US (accounting for around a quarter of all deaths).

"This is a huge study in heart regeneration especially given the smart strategy of using mRNA to deliver Stemin and YAP5SA,"says biologist Siyu Xiao, from the University of Houston.

The research has been published in hereandherein the Journal of Cardiovascular Aging.

Global Surgical Mesh Market Is Estimated To Be Valued At US$ 1.29 Bn In 2022, And Is Forecast To Surpass US$ 2.2 Bn Valuation By The End Of 2032

Sales of surgical meshes are expected to account for more than 21 Mn units by 2032-end, owing to their increasing application in untapped markets, says a Fact.MR analyst.

Fact.MR A Market Research and Competitive Intelligence Provider: The global surgical mesh market is estimated to exceed a valuation of US$ 1.29 Bn in 2022, and expand at a significant CAGR of 5.5% by value over the assessment period (2022-2032).

The availability of surgical meshes in absorbable and non-absorbable forms has expanded their application for temporary as well as permanent reinforcement. In recent years, demand for surgical meshes has escalated in aiding breast reconstruction as they reduce the exposure risk of the implant. Increasing health literacy in North America and Europe will create ample opportunities for surgical mesh manufacturers over the coming years.

Sedentary lifestyle and increasing obesity among the population have resulted in several chronic health issues. The consequent weakening of the muscles extends space for organ prolapse and hernia. Putting these organs back in place by stitching the muscles together can result in muscle tearing and the recurrence of prolapse. However, reinforcing the weakened muscles with the help of a surgical mesh has shown to decrease recurrence and increase the longevity of the repair.

Technical Advancements & Innovative Products Likely to Expand Application of Surgical Meshes in Untapped Domains, States Fact.MR - BioSpace

Amrita Hospitals announced on Thursday that its new 2,400-bed campus will soon be open to the public in Faridabad in August this year. During the press conference on Thursday, hospital management announced that the new Amrita Hospital is spread across 133 acres of land in Faridabad and it will be the biggest private sector hospital in India.

This would be the second large-scale Amrita Hospital in India after the iconic 1,200-bed Amrita Hospital in Kochi, Kerala, which was established 25 years ago by the Mata Amritanandamayi Math.

The new hospital is located at Sector 88, Faridabad and it will have a total built-up area of 1 crore sq. ft., including a 14-floor-high tower that will encompass the key medical facilities and patient areas. During the press conference, Swami Nijamritananda Puri, Head, Mata Amritanandamayi Math, Delhi announced that the 81 specialties at the hospital will include eight centers of excellence, such as oncology, cardiac sciences, neurosciences, gastro-sciences, renal sciences, bone diseases and trauma, transplants, and mother and child.

The hospital will become operational in stages, with 500 beds opening in August this year. In two years, this number will rise to 750 beds, and further to 1,000 beds in five years. When fully operational, the hospital will have a staff of 10,000 people, including over 800 doctors.

On how the new hospital has incorporated the aspects of pandemic-induced demands, Dr. Sanjeev K Singh, Medical Director, Amrita Hospital, Faridabad told Financial Express.com: We have learned a lot from the pandemic. The construction of the hospital began 5-6 years ago and the learnings from the pandemic also got incorporated along the way. For example, any patient who comes in an emergency gets facilitated in a 40-bed setup. In that set-up, we have a decontaminated area in which anyone who needs to shower will be sent there. We have four negative pressure rooms and if we have any suspected cases of covid or covid-like diseases we can send them to concerned specialists. The mechanism of shifting is also planned and implemented. In all critical care units, there are positive pressure isolation rooms.

The massive facility will also include 534 critical care beds which is the highest in India, the hospital management claims. The hospital campus will also include 64 modular operation theaters, most advanced imaging services, fully automated robotic laboratory, high-precision radiation oncology, most updated nuclear medicine, and state-of-the-art 9 cardiac and interventional cath lab for clinical services. Cutting-edge medical research will be a strong thrust area, with a dedicated research block spread across a 7-floor building totaling 3 lakh sq. ft with exclusive Grade A to D GMP lab with focus on identifying newer diagnostic markers, AI, ML, Bioinformatics etc.

Dr. Singh also told Financial Express.com that they want to integrate all aspects of medical science and bridge the gap between clinicians and scientists.

In Kochi, we have established tissue engineering, a nano-medicine-based cardiac stent, bone growth, and lots more. What we are looking at Faridabad campus is developing something new in stem-cell therapies. We want to create techniques like creating human cells on our own in our GMP labs as generally, we rely on international counterparts for such procedures. Recently, we conducted research in which we found that we can use patient pluripetin stem cells in tumours and it will destroy them. For us, oncology is the big thrust area but other areas will be a focus too. The intent of our research facility will be to make the high-end expensive equipment and treatments cost-effective for the common man. We want to integrate medicine, engineering, biotechnology, and other segments altogether, Dr. Singh told Financial Express.com.

Dr. Singh also said that they have already been awarded the Advanced ICMR Clinical Trial Unit and this will enable them to conduct their trials in the new facility.

Mata Amritanandamayi has allocated a certain amount of seed money to initiate research. On the basis of submitted proposals, things will materialise and start, he added.

Dr. Singh also told Financial Express.com that the new hospital will also be empaneled. There is a process of 3-6 months and then after medical facilities will be available under all panels like ECHS, CGHS and other TPAs, he added.

During the press conference, Dr Singh also informed that the hospital will be among the very few facilities in the country to conduct hand transplants, a specialty pioneered by Amrita Hospital in Kochi. We will also do transplants of liver, kidney, trachea, vocal cords, intestine, heart, lung, pancreas, skin, bone, face and bone marrow, he said.

Training of medical students and doctors will be a strong focus area. The hospital will have state-of-the-art robotics, haptic, surgical-medical simulation centre spread across 4 floors and 1.5 lakh sq. ft area, the biggest such learning & development facility for doctors in the country. The facility will also host a medical college and the countrys biggest allied health sciences campus, he stated.

Moreover, the management also informed that ultra-modern Amrita Hospital at Faridabad would be one of Indias largest green-building healthcare projects with a low carbon footprint. It is an end-to-end paperless facility, with zero waste discharge.

There is also a helipad on the campus for swift transport of patients and a 498-room guest house where attendants accompanying the patients can stay, they said.

Stem cells are key building blocks for the human body. At the start of life, they divide over and over again to create a fully developed baby from an embryo. Many individuals now even turn to services that store and preserve umbilical cords should a person ever be in need.

Stem cells have the potential to develop into different types of cells in the body, serving as a repair system of sorts for damaged or lost cells. In recent decades, scientists have shown the miraculous ways of medicine through stem cell treatments.

So just how are doctors using stem cells to treat and help heal people battling various ailments? Heres a look at five studies published on StudyFinds that demonstrate the wondrous ways of stem cell treatments.

A heart condition called dilated cardiomyopathy, or DCM, weakens muscles of the ventricles, which causes heart failure and often death in children. Currently, the only cure is a heart transplant, which can take long periods of time to find an acceptable donor and increases the risk of rejection of the donor tissue. One study finds that stem cell therapy could help DCM patients survive longer while awaiting a transplant or potentially eliminate the need for a new heart entirely.

Cardiac stem cells called cardiosphere-derived cells (CDCs) have proven to be effective at treating certain heart conditions. The CDCs grow into tissue cells of the heart and can counter the effects of DCM. To test the safety of the CDC therapy, a team of scientists at Okayama University in Japan demonstrated the efficacy of CDCs in tissue damaged from DCM. For the study, DCM symptoms were induced in pigs, after which CDCs were administered in various doses for treatment. In a control group, some pigs were given a placebo.

Results showed thickening of the heart muscle in pigs who were given the stem cell treatment. This allows increased blood flowto the rest of the body, thereby effectively repairing the damaged tissue. Due to the dosage used in animal trials, researchers could estimate the proper dosage for human trials.

The first of these included 5 younger patients who were diagnosed with DCM. Injections of CDCs resulted inbetter heart function without any serious side effects. Thus, scientists believe this type of treatment could minimize the need for heart transplants and allow DCM patients to have normal lives.

Although their use is sometimes controversial, scientists often look at stem cells as a potential miracle cure for many conditions. One study finds stem cells from a babys umbilical cord may save the most at risk of dying from COVID-19. A treatment derived from non-altered versions of these stem cells significantly improves the survival rate among coronavirus patients already on a ventilator.

In a double-blind, controlled, randomized study, 40 adultpatients in intensive careand on a ventilator received the treatment intravenously. The infusions contained stem cells coming from the connective tissue of a human umbilical cord. Half of the patients received infusions not containing stem cells to serve as a control group.

Results reveal survival rates climbed by 2.5 times among patients receiving stem cells. Those with a pre-existing health problem, making them high-risk for COVID, saw their changes of beating coronavirus jump by 4.5 times. Moreover, the study says the stem cell infusions did not cause any life-threatening complications or allergic reactions.

In the fight against heart disease, a new super-weapon is now even closer to deployment, and its capabilities are turning out to be beyond expectations. A study aimed at combating heart disease finds that stem cells are not only showing promise in treating heart failure, but in rats are actually reversing problems associated with old age.

The specific type of stem cells used in the study are cardiosphere-derived cells, or CDCs. While the latest research involving CDCs indicates possibilities that have previously been in the realm of science fiction, the scientists leading the charge urge restraint in face of the excitement.

Nevertheless, the latest results of stem cell infusions in rats are startling. Not only did rats that received the CDCs experience improved heart function, they also had lengthened heart cell telomeres. Moreover, the rats that received the treatment also had their exercise capacity increase by about 20 percent. They also regrew hair faster than rats that didnt receive the cells.

Still, the doctors and scientists working to push the frontier of medicine forward are very optimistic about the real possibilities of the therapy. Researchers of the study said they are also studying the use of stem cells in treating patients with Duchenne muscular dystrophy and patients with heart failure with preserved ejection fraction, a condition that affects more than 50 percent of all heart failure patients.

A new biomaterial can help regenerate tissue in people dealing with chronic lower back pain and spinal issues. A recent study finds the secret to this breakthrough therapy is all in the hiPS. Not thosehips, but human induced pluripotent stem cells.

The study explains that a common cause of lower back pain is the degeneration of intervertebral discs (IVDs). These discs sit between the vertebrae in the spine and help give the spinal column its flexibility. Severe IVD degeneration eventually leads to spinal deformity without treatment. In this study, scientists used cartilage tissue derived from stem cells to build back lost IVDs in lab rats.

Study authors used induced pluripotent stem cells (iPSCs) during their experiments. Importantly, scientists are capable of turning iPSCs into chondrocytes cells that produce and maintain cartilage. Previous studies have successfully used this same method to treat cartilage defects in animals. In the new study, researchers created human iPSC-derived cartilaginous tissue (hiPS-Cart) that they implanted into rats with no NP cells in their intervertebral discs.

Findings reveal that the hiPS-Cart implanted in the rats was able to survive and be maintained. IVD and vertebral bone degeneration were prevented. The researchers also assessed the mechanics and found that hiPS-Cart was able to revert these properties to similar levels observed in the control rats.

Stem cells taken from deceased patients may also help in creating a cure for blindness. Retina cells from a corpse continue to survive after being transplanted into the eyes of monkeys, scientists say.

RPE dysfunction is a leading cause of blindness, including causing disorders likemacular degeneration, which affects around 200 million people worldwide. Now, for the first time, scientists have successfully produced retina cells in monkeys using human stem cells. Human cadaver donor-derived cells can be safely transplanted underneath the retina and replace host function, and therefore may be a promising source for rescuing visionin patients with retina diseases.

For the study, researchers transplanted stem cells from the eyes of donated bodies under the monkeys macula, the central part of the retina. Following surgery, the transplanted patches remained stable for at least three months without any serious side-effects. The RPE created by the human stem cells partially took over from the old retina cells. In addition, this could successfully support the eyes light receptorswithout causing retinal scarring.

These unique cells could serve as an unlimited resource of human RPE, whichmay restore sightfor millions of people around the world. The scientists caution that they will need to conduct more research to see how the procedure works with human transplant patients. Human trials are still a long way off.

Global Stem Cell Market To Be Driven By Increasing Activities To Use Stem Cells In Regenerative Medicines In The Forecast Period Of 2022-2027 ...

By Steve Gorman

(Reuters) The first all-private astronaut crew to fly aboard the International Space Station (ISS) headed for splashdown Monday off the coast of Florida, wrapping up a two-week mission that NASA has touted as a landmark in commercial spaceflight.

A SpaceX Crew Dragon capsule carrying the four-man team of Houston-based startup Axiom Space Inc began its return flight about 9 p.m. EDT Sunday (0100 Monday GMT) as it undocked from the space station orbiting about 250 miles (420 km) above Earth.

The Crew Dragon was expected to parachute into the Atlantic around 1 p.m. EDT on Monday (1700 GMT), capping a 16-hour ride home from orbit that had been postponed for several days because of unfavorable weather.

The multinational Axiom team was led by Spanish-born retired NASA astronaut Michael Lopez-Alegria, 63, the companys vice president for business development. His second-in-command was Larry Connor, 72, a technology entrepreneur and aerobatics aviator from Ohio designated the mission pilot.

Joining them as mission specialists were investor-philanthropist and former Israeli fighter pilot Eytan Stibbe, 64, and Canadian businessman and philanthropist Mark Pathy, 52.

Launched from NASAs Kennedy Space Center on April 8, they spent 15 days aboard the space station with the seven regular, government-paid ISS crew members: three American astronauts, a German astronaut and three Russian cosmonauts.

The ISS has hosted several wealthy space tourists from time to time over the years.

But the Axiom quartet was the first all-commercial team ever welcomed to the space station as working astronauts, bringing with them 25 science and biomedical experiments to conduct in orbit. The package included research on brain health, cardiac stem cells, cancer and aging, as well as a technology demonstration to produce optics using the surface tension of fluids in microgravity.

Axiom, NASA and SpaceX have hailed the mission as a milestone in the expansion of privately funded space-based commerce, constituting what industry insiders call the low-Earth orbit economy, or LEO economy for short.

It was the sixth human spaceflight for SpaceX in nearly two years, following four NASA astronaut missions to the ISS and the Inspiration 4 flight in September that sent an all-private crew into Earth orbit for the first time, though not to the space station.

SpaceX, the private rocket company founded by Tesla Inc electric carmaker CEO Elon Musk, has been hired to fly three more Axiom astronaut missions to ISS over the next two years. The price tag for such outings is high.

Axiom charges customers $50 million to $60 million per seat, according to Mo Islam, head of research for the investment firm Republic Capital, which holds stakes in both Axiom and SpaceX.

Axiom also was selected by NASA in 2020 to build a new commercial addition to the space station, which a U.S.-Russian-led consortium of 15 countries has operated for more than two decades. Plans call for the Axiom segment to eventually replace the ISS when the rest of the station is retired around 2030.

The change in the prevalence of HHD

At the global level, the prevalence of HHD increased by 137.91% from 7.82 million in 1990 to 19.60 million in 2019 (Fig.1A, Table S1). The prevalence rate went up year by year, while the ASPR was relatively stable (Fig. 1C). The ASPR was 233.77 (95% UI=170.52312.9) per 100,000 population in 2019, which increased slightly compared with that in 1990 with an EAPC of 0.17 (95% UI=0.150.18) (Fig. 1C, Tables S2 and S3). Compared with the ASPR trend of the female subjects (EAPC, 0.28, 95% UI=0.260.30), the trend of the male subjects was more stable during the study period (EAPC, 0.02, 95% UI=0.000.04, Table S3).

Age-standardized rate of prevalence (C), death (F), and DALY (I). Dashed lines represent 95% uncertainty interval; DALY, disability adjusted life-year

HHD occurred mostly in people aged over 65 (Fig. S1A). We also found that the ASPR increased with age growth for both men and women in 1990 and 2019. The female prevalence rate was much higher than male in people aged over 80 during 2019, yet there was a similar prevalence rate for aged men and women in 1990 (Fig.2).

The gender-specific global prevalence, death, and DALY rate of hypertensive heart disease in 1990 and 2019. The vertical axis represents DALY, death, and prevalence rate (per 100,000 population). DALY, disability adjusted life-year

Among 25 GBD regions, top three regions with the highest prevalence cases were Asia, East Asia, and America. In addition, the three regions with the highest ASPR were East Asia (426.15, 95% UI=306.64574.76), Oceania (344.91, 95% UI=248.54477.87), and Southeast Asia (334.77, 95% UI=244.81451.58) (Table S4). At the national level, China carried the highest HHD prevalence, followed by the United States of America and India (Fig. S2A). The highest ASPR of HHD occurred in Cook Islands, Jordan, Kuwait and Seychelles (Fig. S2C).

A total of 1.16 (95% UI=0.861.28) million people were estimated to experience HHD associated deaths worldwide in 2019, which increased from 0.65 (95% UI=0.530.73) million death cases in 1990 (Table S1). The ASDR in females was 15.05 (95% UI=11.5117.09) per 100,000 population in 2019, which was moderately higher than that in males (14.95, 95% UI=10.3216.75) (Table S2). Although the number of HHD deaths grew up dramatically during 19902019, the trend of death rate was relatively stable and the global ASDR declined with a negative value of EAPC (0.74, 95% UI=-0.92--0.58) (Fig. 1D, E, and F, Table S3). Meanwhile, the male and female ASDR shared a similar trend (EAPC for men, 0.72, 95% UI=-0.95--0.50; EAPC for women, 0.79, 95% UI=-0.93--0.65).

For both men and women, age-specific distribution of death rate remained stable in 1990 and 2019 (Fig. 2). Like HHD prevalence, people aged over 65 were more likely to suffer HHD deaths (Fig. S1B).

At the regional level, Central Sub-Saharan Africa, Eastern Sub-Saharan Africa, North Africa and Middle East had the highest ASDR; Australasia, high-income Asia Pacific and Eastern Europe were the three regions with the lowest ASDR (Table S5). At the national level, China carried the highest HHD death burden, followed by India and the Untied States of America (Fig. S2D). Bulgaria, Afghanistan, and Central African Republic were the three countries with highest ASDR (Fig. S2F).

A total of 21.50 (95% UI=16.4023.90) million DALYs were estimated on a global scale in 2019, and 13.94 (95% UI=11.3115.65) DALYs in 1990 (Table S1). There was a consistent rise in DALY number (Fig. 1G). However, DALY rate declined between 1990 and 2005, then ascended during 20062019 (Fig. 1H). In addition, it shown a persistent decline for the age-standardized DALY rate over the 30years (Fig. 1I).

The age-standardized DALY rate in men was 277.86 (95% UI=199.58311.14) per 100,000 population in 2019, which was higher than that in women (256.81, 95% UI=205.22291.98) (Table S2). The DALY rate distribution for males and females in 2019 was similar to that in 1990 (Fig. 2). In 2019, the age-specific trends of DALY rate attributed to HHD were similar for both sexes.

On the observation of the regions scale, Central Sub-Saharan Africa, Eastern Sub-Saharan Africa, and Oceania were the three regions with the highest age-standardized DALY rates (Table S5). It revealed a considerable national disparity in the burden of HHD. DALY numbers varied more than 10-fold between countries (Fig.3A). China had the highest HHD DALY number, followed by India and Indonesia (Fig. 3D). After adjusting population, Bulgaria, Estonia, and Cook Islands were the three countries with the highest rate of DALYs (Fig. 3B and E). After adjusting for age and population, Afghanistan, Cook Islands, and Central African Republic had the highest age-standardized DALY rates (Fig. 3C and F).

Global map of the disease burden of hypertensive heart disease (A, DALY number; B, DALY rates; C, Age-standardized DALY rates) and the top 20 countries with disease burden (D, DALY number; E, DALY rates; F, Age-standardized DALY rates)

The drift of HHD-related ASPR, ASDR, and age-standardized DALYs rate among five SDI quintiles were presented in Fig.4. The ASPR of HHD was highest in the middle SDI region, and the lowest in the high SDI region between 1990 and 2019 (Fig. 4A). It was interesting to note that, as opposed to the regions with other SDI, the middle SDI region presented a descending trend of ASPR (EAPC, 0.24, 95% UI=-0.2--0.20) (Table S3). ASDR and age-standardized DALY rate decreased the fastest in the middle SDI region (EAPC, 1.58, 95% UI=-1.98--1.20 for ASDR; EAPC, 1.74, 95% UI=-2.11--1.41 for age-standardized DALY rate) (Table S3, Fig. 4B and C). In the middle SDI region, the trend of ASDR and age-standardized DALY rate presented undulating curves (Fig. 4B and C). Compared with a downward trend for females (EAPC, 0.28, 95% UI=-0.4--0.11), male age-standardized DALY rate showed an upward tendency in the high SDI region (EAPC, 0.34, 95% UI=0.110.57).

ASPR, ASDR, and age-standardized DALY rate of HHD stratified by SDI were shown in Fig.5. ASPR of HHD rose before SDI value of 0.4 and then start to decrease (Fig. 5A). There was a negative and significant Pearsons correlation between HHD disease burden and SDI (r=0.74, 95% CI=-0.77--0.70, p<0.001, for age-standardized DALY rate; r=0.70, 95% CI=-0.74--0.66, p<0.001, for ASDR) (Fig. 5C). The univariate linear regression indicated that many socioeconomic variables (HDI, IHDI, SDI, HAQ, population with at least some secondary education, life expectancy, and physicians per 10,000 people) had a significantly negative correlation with age-standardized DALY rate (all p<0.001, Table1).

Highland Therapeutics Announces Appointment of Stephanie C. Read as President/CEO, Changes to Board of Directors - BioSpace

Inflammation represents one of the leading drivers of disease. Biotech company 180 Life Sciences is developing novel, anti-TNF therapies for treating distinct inflammatory diseases.

DocWire News spoke to James Woody, CEO of 180 Life Sciences, to learn more about the company, its mission, its treatment assets, and current clinical trials its involved in.

*Interview recorded in March 2022.

DocWire News: Can you give us some background on yourself, and the company, 180 Life Sciences?

James Woody: So by background, Im a pediatric immunologist, and in my prior life, I was Chief Scientific Officer of a company called Centocor, which was one of the very early biotech companies. And we were the first ones ever to make a anti-TNF antibody and to test it in patients, and we were able to show that it was remarkably effective in patients with rheumatoid arthritis, Crohns disease and psoriasis and ulcerative colitis. And that actually began the pretty much the whole antibody based biologics industry. We were the first ones to do this with a humanized antibody.

I went on from there to run a pharmaceutical company called Syntex, former Syntex that was after Roche bought it and did that for eight years, we invented a lot of small molecules. And then I went on to start a company in oncology, cancer stem cells. And from there I went over to the dark side and joined a venture capital group and helped start companies for about 10 years and some of them are really successful. Some of them are okay and some crashed and burned, but thats the nature of the business. And then more recently I helped start a couple companies on my own. And then I was approached by the founders of 180 LS to help them out and also to be CEO of their company, so thats how I came to be CEO of 180 Life Sciences.

180 Life Sciences is repurposing anti-TNF for unmet needs. What is anti-TNF?

So in your body, you have lots of protein circulating around in your blood. These tell the body cells what to do, and some of them are called cytokines and cytokines are the ones that kind of tell your immune system what to do. And theres quite a lot of these. And theres some of em that are very good. Theres some of them that are bad actors and one of them is called tumor necrosis factor. It was named that totally by accident because it seemed to eliminate tumors in mice, but thats never been able to be shown in humans, but the name has stuck with it. So tumor necrosis factor is the thing that causes some types of inflammation, if theres an overproduction. For example, in rheumatoid arthritis, its the tumor necrosis factor that drives the destruction of the joints of your fingers and knees and shoulders and everything, so its a destructive cytokine. And what we did is we made a specialized antibody against TNF that binds it up and blocks it and prevents it from causing the inflammation. And that was the basis of infliximab or Remicade that we discovered from Centocor.

What is Dupiytrens disease, how is it characterized?

Dupuytrens Contracture is kind of a chronic disease, but it affects quite a lot of people, maybe 16 or 20 million in the US, same in Europe. It starts out as a small nodule in your palm. And over time, maybe a couple of years, some faster, some slower, it begins to form cords underneath the palm of your hand, it pulls your fingers together and contracts them. Sometimes this is inherited in families and sometimes it just occurs. So what happens is that this nodule starts, and as I said, over time, the fingers become contracted. So theres no therapies for the early stage when the nodules just form, but thats the basis of what were doing, Ill talk about that in a minute.

Later on, after the fingers are already contracted and you have the disability, you cant button your clothes, you cant type with that hand. You cant do many of the things that you like to do with your hand. Theres several therapies that they try. One of them is injecting a collagenase thats partially effective, but they all, about half of those recur. You can try to disrupt these cords with a needle called needle aponeurectomy or alternatively, what happens is you end up going to surgery and they cut these cords out. Ironically, my wife had this and went through a whole year of steroid injections into her hand, finally had to have the surgery. So Im familiar with the process. But thats what happens, and I think people, as soon as the nodule forms, people these days, because they have Dr. Google, can immediately know whats going to happen in the long run, so the information out there is quite impressive.

180 Life Sciences recently completed a Phase 2 study for Duputyrens. Tell us about the study protocol, the drug used and other updates on the study.

Our colleague in England, Dr. Jagdeep Nanchahal, was able to look at Dupuytrens Contracture and especially the nodules, and through a series of very elegant experiments, he was able to show that the nodule was driven by the TNF, the bad actor. And in this case, the inflammation caused the fibrosis that were talking about, that leads to the finger contracture. And so he was able to work out that if you inject anti-TNF into this nodule, you can impact the course of the disease.

And so he did a very large trial of about 150 patients in the UK and was able to inject anti-TNF into the nodules of their hands. And in that trial, which took over a year, there were three or four injections, but we were able to show that both the primary and secondary endpoints of the trial were met and the endpoints had to do with the size of the nodule, whether it was growing, whether it was shrinking, whether it was hard or whether it was soft or whether the fingers were contracting, all of that, but we met the primary endpoints and the full publication with all the details will be out, hopefully in the next couple of months.

You have another trial planned for Frozen Shoulder. What is Frozen Shoulder, and how will the trial aim to address it?

Yes, Frozen Shoulder is another kind of inflammatory condition where fibrosis forms in the shoulder. And it initially starts out as being extremely painful. And that goes on for several months and then eventually the pain subsides, but the shoulder becomes totally immobile. And eventually you have to have surgery to remove the fibrotic tissues. Interestingly enough, this occurs more common in patients with diabetes, but about half of those patients also have Dupuytrens. And so we think that the fibrosis in the Dupuytrens and the fibrosis in the shoulder is the same mechanism. And so Dr. Nanchahal will be injecting anti-TNF into the shoulder very early, as soon as the pain is evident, then hell try to inject anti-TNF and maybe relieve the pain and also the formation of the fibrosis, so that one can avoid the surgery, which is actually quite expensive. And also, theres quite a long course of physical therapy after the surgery, so its something youd like to avoid. And so were trying to treat patients both with Dupuytrens and Frozen Shoulder before the disability develops.

A third program, which is soon to be clinical, is anti-TNF for post-operative cognition delirium or POCD. Tell me about POCD, and the preliminary research that led the team to pursue this indication?

We know that now that theyre doing fairly aggressive surgery in older patients, either hip replacements or emergency hip corrections or CABG procedure, coronary artery bypass graft, or cardiac surgery, that a fair percentage of these people after the surgery, just have a foggy brain. And the fog goes on for some time and we call it postoperative cognitive dementia, as the technical term. And in some patients, maybe 15 or 20%, it doesnt go away. And they end up in nursing homes and they actually dont live very long after that. And so our colleagues in the UK, Dr. Nanchahal and Dr. Feldman and his colleagues, have shown that during the surgery, any kind of aggressive surgery, that TNF is released from the tissue damage, and the TNF goes to the brain and opens it up and lets inflammatory cells get into the area of the brain thats where your cognitive areas are, and so that leads to the dementia.

And in the past, theyve thought this all had to do with the anesthesia, but we think its the TNF thats actually causing this dementia going forward. And so were actually going to do a trial in patients that are having their hip repaired that are older, and were going to administer one dose of anti-TNF just before the surgery starts with a view towards preventing the dementia going forward. So this will be a long trial, but if it works, itll be something that everybody who goes into major surgery would want to have. So its another exciting opportunity for 1-ADLS and our investigators.

180 Life Sciences recently announced licensing of a compound called HMGB1. Tell us more about HMGB1 and the companys plans for it.

The company is also working on other areas of fibrosis, not just Dupuytrens Contracture and Frozen Shoulder, but other areas like liver fibrosis, which occurs with NASH. And we are working on ways to prevent that as well, much like were working on Dupuytrens and Frozen Shoulder. The fibrosis in the liver is really hard to reverse, and there are no real agents that do that, but theres a lot of people trying different things. Now what the HMGB-1 does, it doesnt change the fibrosis, but once the fibrosis is stopped, it could help the liver cells to regenerate. So this is kind of a regenerative medicine. It makes the tissues regenerate, whether its heart or whether its liver or whether its lung or whatever. And so its going to be used after the fibrosis is stopped. And so thats kind of what were interested in. And were just getting that program off the ground and making the initial compounds to do our testing.

Any closing thoughts?

Well, Id like to talk about our team. The company was founded by Dr. Mark Feldman, who was the one, he was the original person who figured out that TNF was causing the joint destruction and arthritis, and with TNI and others, that actually did the very first trials ever. And this was done in patients with wheelchairs and they actually got up out of their wheelchairs and walked around. It was a phenomenal moment. We had no idea it would work that well. And some of them actually did a pirouette down some stairs. We have videos of this. So its kind of like The Awakening movie where they gave them the L-DOPA and they all woke up. Well, in this case, they got up out of their wheelchairs and theres no patients in wheelchairs with rheumatoid arthritis in the whole world because of that drug, and the ones that followed on.

The current Humira from AbbVie is the preferred one. But the whole idea and concept, we started back then. Other founders, Dr. Larry Steinman, he and Mark put the 1-ADLS together. And he developed Tysabri, the very first drug to help MS patients. And it was another phenomenal discovery that he made. And hes also working on MS and other areas. But so we have the leaders in inflammation as the people who actually founded the company. So its a pleasure to work with them. Ive been acquainted with them off and on for the past, maybe 25 years, so working with them again is a real pleasure.

James Woody, CEO of 180 Life Sciences: Developing New Therapies to Treat Inflammatory Diseases - DocWire News

The SARS-CoV-2 virus can infect specialized pacemaker cells that maintain the hearts rhythmic beat, setting off a self-destruction process within the cells, according to a preclinical study co-led by researchers at Weill Cornell Medicine, NewYork-Presbyterian and NYU Grossman School of Medicine. The findings offer a possible explanation for the heart arrhythmias that are commonly observed in patients with SARS-CoV-2 infection.

In the study, reported March 8 in Circulation Research, the researchers used an animal model as well as human stem cell-derived pacemaker cells to show that SARS-CoV-2 can readily infect pacemaker cells and trigger a process called ferroptosis, in which the cells self-destruct but also produce reactive oxygen molecules that can impact nearby cells.

This is a surprising and apparently unique vulnerability of these cellswe looked at a variety of other human cell types that can be infected by SARS-CoV-2, including even heart muscle cells, but found signs of ferroptosis only in the pacemaker cells, said study co-senior author Dr. Shuibing Chen, the Kilts Family Professor of Surgery and a professor of chemical biology in surgery and of chemical biology in biochemistry at Weill Cornell Medicine.

Arrhythmias including too-quick (tachycardia) and too-slow (bradycardia) heart rhythms have been noted among many COVID-19 patients, and multiple studies have linked these abnormal rhythms to worse COVID-19 outcomes. How SARS-CoV-2 infection could cause such arrhythmias has been unclear, though.

In the new study, the researchers, including co-senior author Dr. Benjamin tenOever of NYU Grossman School of Medicine, examined golden hamstersone of the only lab animals that reliably develops COVID-19-like signs from SARS-CoV-2 infectionand found evidence that following nasal exposure the virus can infect the cells of the natural cardiac pacemaker unit, known as the sinoatrial node.

To study SARS-CoV-2s effects on pacemaker cells in more detail and with human cells, the researchers used advanced stem cell techniques to induce human embryonic stem cells to mature into cells closely resembling sinoatrial node cells. They showed that these induced human pacemaker cells express the receptor ACE2 and other factors SARS-CoV-2 uses to get into cells and are readily infected by SARS-CoV-2. The researchers also observed large increases in inflammatory immune gene activity in the infected cells.

The teams most surprising finding, however, was that the pacemaker cells, in response to the stress of infection, showed clear signs of a cellular self-destruct process called ferroptosis, which involves accumulation of iron and the runaway production of cell-destroying reactive oxygen molecules. The scientists were able to reverse these signs in the cells using compounds that are known to bind iron and inhibit ferroptosis.

This finding suggests that some of the cardiac arrhythmias detected in COVID-19 patients could be caused by ferroptosis damage to the sinoatrial node, said co-senior author Dr. Robert Schwartz, an associate professor of medicine in the Division of Gastroenterology and Hepatology at Weill Cornell Medicine and a hepatologist at NewYork-Presbyterian/Weill Cornell Medical Center.

Although in principle COVID-19 patients could be treated with ferroptosis inhibitors specifically to protect sinoatrial node cells, antiviral drugs that block the effects of SARS-CoV-2 infection in all cell types would be preferable, the researchers said.

The researchers plan to continue to use their cell and animal models to investigate sinoatrial node damage in COVID-19and beyond.

There are other human sinoatrial arrhythmia syndromes we could model with our platform, said co-senior author Dr. Todd Evans, the Peter I. Pressman M.D. Professor of Surgery and associate dean for research at Weill Cornell Medicine. And, although physicians currently can use an artificial electronic pacemaker to replace the function of a damaged sinoatrial node, theres the potential here to use sinoatrial cells such as weve developed as an alternative, cell-based pacemaker therapy.

Many Weill Cornell Medicine physicians and scientists maintain relationships and collaborate with external organizations to foster scientific innovation and provide expert guidance. The institution makes these disclosurespublic to ensure transparency. For this information, see profiles for Dr. Todd Evans, and Dr. Robert Schwartz.

About BioRestorative Therapies, Inc.

BioRestorative Therapies, Inc. (www.biorestorative.com) develops therapeutic products using cell and tissue protocols, primarily involving adult stem cells. Our two core programs, as described below, relate to the treatment of disc/spine disease and metabolic disorders:

Disc/Spine Program (brtxDISC): Our lead cell therapy candidate, BRTX-100, is a product formulated from autologous (or a persons own) cultured mesenchymal stem cells collected from the patients bone marrow. We intend that the product will be used for the non-surgical treatment of painful lumbosacral disc disorders or as a complementary therapeutic to a surgical procedure. The BRTX-100 production process utilizes proprietary technology and involves collecting a patients bone marrow, isolating and culturing stem cells from the bone marrow and cryopreserving the cells. In an outpatient procedure, BRTX-100 is to be injected by a physician into the patients damaged disc. The treatment is intended for patients whose pain has not been alleviated by non-invasive procedures and who potentially face the prospect of surgery. We have received authorization from the Food and Drug Administration to commence a Phase 2 clinical trial using BRTX-100 to treat chronic lower back pain arising from degenerative disc disease.

Metabolic Program (ThermoStem): We are developing a cell-based therapy candidate to target obesity and metabolic disorders using brown adipose (fat) derived stem cells to generate brown adipose tissue (BAT). BAT is intended to mimic naturally occurring brown adipose depots that regulate metabolic homeostasis in humans. Initial preclinical research indicates that increased amounts of brown fat in animals may be responsible for additional caloric burning as well as reduced glucose and lipid levels. Researchers have found that people with higher levels of brown fat may have a reduced risk for obesity and diabetes.

BioRestorative Therapies Announces Nomination of Two New Members to the Board of Directors - StreetInsider.com

VANCOUVER, BC, Oct. 21, 2021 /PRNewswire/ -- The global culture media market size was USD 5.43 billion in 2020 and is expected to register a CAGR of 9.3% between 2021 and 2028. Steady market revenue growth is driven by rising need for monoclonal antibodies, growing emphasis on personalized medicine, increasing prevalence of infectious diseases, rising investment in research & development of innovative cell culture products, rising awareness about vaccines based on cell culture, and high demand for single-use technologies.

Drivers: Increased Investment in Research & Development of Innovative Cell Culture Products

Increased investment in research & development of innovative cell culture products is a key factor driving culture media market revenue growth. Cell culture media is an important component in producing cultivated meat. Cell culture media is necessary to keep the cells healthy and alive. Currently, most of these media are very expensive and oftentimes deliver inconsistent outcomes. A limited number of species-specific formulations of commercial culture media exists in case of cultivated meat firms dealing with fish species. For instance; in September 2020, GFI announced providing a two-year grant to a research project focused on development of a serum-free, high-quality fish cell culture media, which is an essential move in making cultivated seafood to reach market. Researchers at Virginia Tech are developing a formulation for open-source media improved for growing fish cells. This research project deploys artificial neural networks and Response Surface Methodology (RSM) to optimize cell culture media for better thriving of fish cells.

Restraints: Cost Prohibitive Culture Media and Contamination Risks

Cost prohibitive culture media and contamination risks may hamper market revenue growth over the forecast period. Culture media comprise various ingredients such as serum and nutrients for cell growth, which makes the product very costly. Also, issues associated with specificity, variability, and standardization may also impact market revenue growth negatively. Sometimes, ingredients procured from poor sources can lead to contamination risks of cell culture media. This factor would also restrain demand for culture media.

Growth Projections

The global culture media market size is expected to reach USD 11.10 billion in 2028 and register a revenue CAGR of 9.3% over the forecast period, attributed to growing population, especially geriatric population, and rising prevalence of infectious diseases. Increasing prevalence of infectious diseases and rising need for development of more efficient drugs to combat resulting conditions are driving market revenue growth. Infectious diseases are considered to be the foremost cause of mortalities across the globe, particularly in young children living in low-income countries. As per the World Health Organization (WHO), diarrheal diseases and lower respiratory infections were included in the top 10 leading causes of death worldwide in 2019. Culture technologies are considered crucial for identification of infectious diseases, despite significant increase in molecular testing, as pathogenic organisms causing disease are required to be separated from other microbes in mixed cultures. In addition, occurrence of an organism is necessary for assessing the probability that a specific organism is responsible for a said disease, unlike a culture.

COVID-19 Direct Impacts

COVID-19 pandemic has boosted demand for culture media, as many biotechnology firms are conducting in-vitro R&D for vaccines and antivirals. In-vitro assessment of vaccines normally requires a culture media for identifying and analyzing the response and growing targeted microbes. Increasing emphasis on research & development of vaccines by various pharmaceutical companies to curb spread of COVID-19 virus is also propelling market revenue growth.

Current Trends and Innovations

Increasing trend of single-use technologies plays a pivotal role in driving market revenue growth. In the biotechnology industry, use of single-use technologies has become a common practice. Engineers and researchers are utilizing plastic components as an alternative to stainless steel items in biomanufacturing processes. In cell culture production, adoption of single-use is quite essential and these cell growth systems may be wave-type bioreactors, plastic bioreactors, or plastic linings present in stainless-steel support. Reusable or disposable probes are present in all systems that protrude through an interior sleeve or attach to the outside. Majority of the connections depend on separate systems having aseptic/plastic connectors. Single-use systems are pre-cleaned and pre-sterilized, generally via gamma irradiation. Hence, there is no requirement for cleaning, sterilization, or sanitization steps. It saves money on use of chemicals for cleaning, as well as power and equipment needed to produce pure water and steam.

Geographical Outlook

Culture media market in Asia Pacific is expected to register fastest revenue CAGR during the forecast period, attributed to increasing geriatric population in countries such as Japan and China and increase in prevalence of chronic diseases. In addition, increasing prevalence of contagious diseases, high demand for personalized medication, and presence of biotechnology firms such as Daiichi Sankyo Company Limited and large population base in countries in the region are also contributing to market growth.

Strategic Initiatives

In December 2018, Fujifilm acquired IS Japan (ISJ) and Irvine Scientific Sales Company (ISUS). Both companies have expertise and technological know-how on cell culture media. Irvine Scientific Sales Company distributes its products mostly in Europe and the US, whereas IS Japan distributes its products primarily in Japan and various other Asian countries. Both of these firms offer culture media to bio-ventures, pharmaceutical companies, and academia. Fujifilm is a photography and imaging firm in Japan. It has entered into stock purchase contract worth approximately USD 800.0 million.

ABSTRACT

COVID-19 affects multiple organs. Clinical data from the Mount Sinai Health System shows that substantial numbers of COVID-19 patients without prior heart disease develop cardiac dysfunction. How COVID-19 patients develop cardiac disease is not known. We integrated cell biological and physiological analyses of human cardiomyocytes differentiated from human induced pluripotent stem cells (hiPSCs) infected with SARS-CoV-2 in the presence of interleukins, with clinical findings related to laboratory values in COVID-19 patients, to identify plausible mechanisms of cardiac disease in COVID-19 patients. We infected hiPSC-derived cardiomyocytes, from healthy human subjects, with SARS-CoV-2 in the absence and presence of IL-6 and IL-1. Infection resulted in increased numbers of multinucleated cells. Interleukin treatment and infection resulted in disorganization of myofibrils, extracellular release of troponin-I, and reduced and erratic beating. Infection resulted in decreased expression of mRNA encoding key proteins of the cardiomyocyte contractile apparatus. Although interleukins did not increase the extent of infection, they increased the contractile dysfunction associated with viral infection of cardiomyocytes resulting in cessation of beating. Clinical data from hospitalized patients from the Mount Sinai Health System show that a significant portion of COVID-19 patients without prior history of heart disease, have elevated troponin and interleukin levels. A substantial subset of these patients showed reduced left ventricular function by echocardiography. Our laboratory observations, combined with the clinical data, indicate that direct effects on cardiomyocytes by interleukins and SARS-CoV-2 infection might underlie heart disease in COVID-19 patients. Importance SARS-CoV-2 infects multiple organs including the heart. Analyses of hospitalized patients show that a substantial number without prior indication of heart disease or comorbidities show significant injury to heart tissue assessed by increased levels of troponin in blood. We studied the cell biological and physiological effects of virus infection of healthy human iPSC cardiomyocytes in culture. Virus infection with interleukins disorganizes myofibrils, increases cell size and the numbers of multinucleated cells, suppresses the expression of proteins of the contractile apparatus. Viral infection of cardiomyocytes in culture triggers release of troponin similar to elevation in levels of COVID-19 patients with heart disease. Viral infection in the presence of interleukins slows down and desynchronizes the beating of cardiomyocytes in culture. The cell level physiological changes are similar to decreases in left ventricular ejection seen in imaging of patients hearts. These observations suggest that direct injury to heart tissue by virus can be one underlying cause of heart disease in COVID-19.

A genetic syndrome that affects bones

Osteogenesis Imperfecta (OI) is a hereditary disorder occurring in 1:10,000 births and characterised by osteopenia (bone loss) and skeletal fragility (fractures). Secondary features include short stature, skeletal deformities, blue sclera and dentinogenesis imperfect. (1) There is a large clinical variability in OI, and severity ranges from mild to lethal, based on radiological characteristics. Genetically, OI is a collagen-related syndrome. Type I collagen is a heterotrimeric helical structure synthesized by bone-forming cells (osteoblasts), and it constitutes the most abundant protein of the skeletal organic matrix. (2) Synthesis of type I collagen is a complex process. (3) Collagen molecules are cross-linked into fibrils (which confer tensile strength to the bones). Those are then mineralised by hydroxy-apatites (which provides compressive strength) and assembled into fibres.

Dominant mutations in either the COL1A1 or the COLA1A2 genes are responsible for up to 90% of all OI cases. These mutations (more than 1,000 of which have been identified) lead to impairment of collagen structure and production, which in either quantitative or qualitative bone extracellular matrix (ECM) defects. Mutations affecting ECM structure have serious health consequences because the skeleton protects visceral organs and the central nervous system and provides structural support. Bones also store fat in the yellow bone marrow found within the medullary cavity, whilst the red marrow located at the end of long bones is the site of haematopoiesis. In addition, the ECM constitutes a reservoir of phosphate, calcium, and growth factors, and is involved in trapping dangerous molecules.

Stem cell therapy for OI aims to improve bone quality by harnessing the ability of mesenchymal stem cells (MSC) to differentiate into osteoblasts, with the rationale that donor cells would engraft into bones, produce normal collagen and function as a cell replacement. Stem cells have, therefore, been proposed for the treatment of OI (4) and, in particular, prenatal foetal stem cell therapy (foetal stem cells injected into a foetus, i.e. foetal-to-foetal) approach, which offers a promising route to effective treatment. (5) Human foetal stem cells are more primitive than stem cells isolated from adult tissues and present advantageous characteristics compared to their adult counterparts, i.e. they possess a higher level of plasticity, differentiate more readily into specific lineages, grow faster, senesce later, express higher levels of adhesion molecules, and are smaller in size. (6,7) Prenatal cell therapy capitalises on the small size of the foetus and its immunological naivete. In addition, stem cells delivered in utero benefit from the expansion of endogenous stem cells and may prevent organ injury before irreversible damage. (8)

However, human foetal stem cells used are isolated from either foetal blood drawn by cardiac puncture, either during termination of pregnancy or during ongoing pregnancy, albeit using an invasive procedure associated with a high risk of morbidity and mortality for both the foetus and the mother (9). Foetal cells can also be isolated from the first-trimester liver (following termination of pregnancy) and such cells are currently used in The Boost Brittle Bones Before Birth (BOOSTB4) clinical trial, which aims to investigate the safety and efficacy of transplanting foetal derived MSCs prenatally and/or in early postnatal life to treat severe Osteogenesis Imperfecta (OI) (10). Alternatively, foetal stem cells can be isolated during ongoing pregnancy from the amniotic fluid, either during mid-trimester amniocentesis or at birth (11,12) or from the chorionic villi of the placenta during first-trimester chorionic villi sampling (13).

We have demonstrated that human fetal stem cells isolated from first trimester blood possess superior osteogenic differentiation potential compared to adult stem cells isolated from bone marrow and to fetal stem cells isolated from first trimester liver. We showed that in utero transplantation of these cells in an experimental model of severe OI resulted in a drastic 75% decrease in fracture rate incidence and skeletal brittleness, and improvement of bone strength and quality.(14) A similar outcome was obtained using placenta-derived foetal stem cells (15) and amniotic fluid stem cells following perinatal transplantation into experimental models. (16,17)

Understanding the mechanisms of action of donor cells will enable the engineering of donor cells with superior efficacy to stimulate bone formation and strengthen the skeleton. Despite their potential to differentiate down the osteogenic lineage, there is little evidence that donor cells contribute to regenerating bones through direct differentiation, due to the very low level of donor cell engraftment reported in all our studies. When placed in an osteogenic microenvironment in vitro, foetal stem cells readily differentiate into osteoblasts and produce wild type collagen molecules. However, there are insufficient proofs that collagen molecules of donor cell origin contribute to the formation of the host bone ECM to confer superior resistance to fracture.

It is now well accepted that stem cells can influence the behaviour of target cells through the release of paracrine factors and, therefore, contribute to tissue regeneration indirectly. We have indeed recently shown that donor stem cells stimulate the differentiation of resident osteoblasts, which were unable to fully mature in the absence of stem cell treatment. (16,17) We are now focusing our efforts on understanding the precise molecular mechanisms by which donor cells improve skeletal health to counteract bone fragility caused by various OI-causative mutations.

Introduction

The growing burden of ischemic heart disease (IHD) is a major public health issue. The most harmful type of IHD is acute myocardial infarction (MI), which leads to loss of tissue and impaired cardiac performance, accounting for two in five deaths in China.1 Timely revascularization after MI, including percutaneous coronary intervention, thrombolytic treatment and bypass surgery, is key to improving cardiac function and preventing post-infarction pathophysiological remodeling.2 However, these effective but invasive approaches cannot be used in all patients owing to their applicability, which is limited based on specific clinical characteristics, and the possibility of severe complications such as bleeding and reperfusion injury.2,3 Attempts to limit infarct size and improve prognosis using pharmacotherapy (including antiplatelet and antiarrhythmic drugs and angiotensin-converting enzyme inhibitors) without reperfusion has been proven generally inefficient, due to non-targeted drug distribution and side effects, and short half-life of some drugs.1,3,4 Consequently, many patients in which this approach is used still progress to cardiac hypertrophy and heart failure.1 Growth and rupture of atherosclerotic plaques and the ensuing thrombosis are the major causes of acute MI.4 Currently available interventions for atherosclerosis (AS) including statins can reduce acute MI, but the effects vary between individuals, and leave significant residual risks.58 Some chemotherapies, such as docetaxel9 and methotrexate,10,11 also seem to have beneficial effects in AS; however, systemic administration of these drugs is limited because of their adverse effects.12 The demand for safer and more efficient therapies and prevention strategies for MI is therefore increasing.

Several optimized strategies have so far been explored, one of which is the application of nanoparticles (NPs). These nanoscale particles have been widely used in the treatment of tumors and neural diseases.13,14 NPs enable delivery of therapeutic compounds to target sites with high spatial and temporal resolution, enhancement of tissue engineering processes and regulation of the behaviour of transplants such as stem cells. The application of NPs improves the therapeutic effects and minimizes the adverse effects of traditional or novel therapies, increasing the likelihood that they can be successfully translated to clinical settings.1518 However, research on NPs in this field is still in its infancy.5,1921 This review summarizes the latest NP-based strategies for managing acute MI, mostly published within the past 7 years, with a particular focus on effects and mechanisms rather than particle types, which have been extensively covered in other reviews (Figure 1). In addition, we offer an initial viewpoint on the value of function-based systems over those based on materials, and discuss future prospects in this field.

Figure 1 Overview of nanoparticle-based strategies for the treatment and prevention of myocardial infarction. Nanoparticles are capable of delivering therapeutic agents and nucleic acids in a stable and targeted manner, improving the properties of tissue engineering scaffolds, labeling transplanted cells and regulating cell behaviors, thus promoting the cardioprotective effects of traditional or novel therapies.

A multitude of NP types are currently under investigation, including lipid-based NPs, polymeric NPs, micelles, inorganic NPs, and exosomes. Virus can also be considered as NPs; however they will not be discussed in this review.22 NPs made from different materials show similar in vivo metabolic kinetic characteristics and protective effects on infarcted heart.19,20 Function-based NP types, oriented towards a specific purpose, may be preferable compared with traditional types, on account of their practicality in basic research and clinical translation. In this review, we discuss NPs used in the treatment and prevention of MI that fall into the following four categories: 1) circulation-stable nanocarriers (polymeric, lipid or inorganic particles); 2) targeted delivery vectors (magnetic or particles modified to improve target specificity); 3) enhancers of tissue engineering; and 4) regulators of cell behavior (Figure 1). We propose that the choice of each NP for any given application should be primarily based on the roles or mechanisms they perform.

Many NPs, whether composed of either naturally occurring or synthetic materials, act as nanocarriers to improve the circulating stability of therapeutic agents.15,16 Polymeric NPs comprise one of the most widely employed types, with excellent biocompatibility, tunable mechanical properties, and the ability be easily modified with therapeutic agents using a broad range of chemical techniques.23,24 The most commonly used polymer for these NPs is polylactide-co-glycolide (PLGA), which has Food and Drug Administration approval.25,26 Recently, there has been a therapeutic emphasis on polydopamine (PDA), from which several related nanomaterials have been created, including PDA NPs and PDA NP-knotted hydrogels.27,28 NPs made from polylactic acid (PLA),29,30 poly--caprolactone (PCL),31 polyoxalates,32 polyacrylonitrile,33 chitosan29,34 and hollow mesoporous organosilica35 have also been constructed and administered in vitro in cells and in vivo in animal models.

Lipid NPs or liposomes are also considered promising candidates for the delivery of therapeutic agents, due to their morphology, which is similar to that of cellular membranes and ability to carry both lipophilic and hydrophilic drugs. These non-toxic, non-immunogenic and biodegradable amphipathic nanocarriers can be designed to reduce capture by reticuloendothelial cells, increase circulation time, and achieve satisfactory targeting.36,37 Solid lipid NPs (SLNs) combine the advantages of polymeric NPs, fat emulsions, and liposomes, remaining in a solid state at room temperature. Active key components of SLNs are mainly physiological lipids, dispersed in aqueous solution containing a stabilizer (surfactant).38 Micelles are made by colloidal aggregation in a solution through self-assembly of amphiphilic polymers, or a simple lipidic layer of transfer vehicles;39 these have been used in cellular and molecular imaging40 and treatment41 for a long time.

Inorganic NPs used in basic IHD research are classified as metal, metal compounds, carbon,42 or silicon NPs;43 these are relatively inert, stable, and biocompatible. Gold (Au),44 silver (Ag)45 and copper (Cu)46 are commonly used materials in their production. These NPs can be delivered orally,47 or injected intravenously48 or intraperitoneally.56 However, they are more widely used to construct electrically conductive myocardial scaffolds in tissue engineering.49,50 Myocardial patches and scaffolds are promising therapeutic approaches to repairing heart tissue after IHD; incorporating conductive NPs can further improve functionality, introducing beneficial physical properties and electroconductivity. Some organic particles, such as liposomes anchored with poly(N-isopropylacrylamide)-based copolymer groups, are also suitable for the production of effective nanogels or patches for this purpose.37

Several metal compounds have been used for treatment of IHD.5154 The application of magnetic particles made from iron oxide has been of particular interest in recent research. These NPs are more prone to manipulation with an external magnetic field, and thus serve as powerful tools for targeted delivery of therapeutics. In addition, modification with targeted peptides or antibodies is another approach to the construction of targeted delivery systems.

Another strategy to protect cardiac performance after MI is the transplantation of cells; however, the beneficial effects of this are currently limited.58 Many NPs can improve the behavior of cells; in this context, they may stimulate cardioprotective potential. In particular, exosomes a major subgroup of extracellular vesicles (EVs) with a diameter of 30150nm, which are secreted via exocytosis55 represent novel, heterogeneous, biological NPs with an endogenous origin. They are able to carry a variety of proteins, lipids, nucleic acids, and other bioactive substances.5557 Mechanistic studies have confirmed that exosomes offer a cell-free strategy to rescue ischemic cardiomyocytes (CMs).59,60

The physical properties of NPs, including size, shape, and surface charge, impact on how biological processes behave, and consequently, responses in the body.61 The recommended definition of NPs in pharmaceutical technology and biomedicine includes a limitation that more than 50% of particles should be in a size distribution range of 10100 nm.39 However, this is not strictly distinguished in studies, so for the purposes of this review, we have relaxed this definition. Small NPs have a faster uptake and processing speed and longer blood circulation half-lives than larger ones; a decreased surface area results in increased reactivity to the microenvironment and greater speed of release of the compounds they carry.6163 However, an exception to this principle is that, among particles of less than 50 nm diameter, larger NPs have longer circulatory half-lives.64,65 NPs can be spherical, discoidal, tubular or dendritic.61,63 The impact of NP shape on uptake and clearance has also been revealed;66,67 for instance, spheres endocytose more easily,20 while micelles and filomicelles target aortic macrophages, B cells, and natural killer (NK) cells in the immune system more effectively than polymersomes.68 In terms of charge, cationic NPs are more likely to interact with cells than negatively charged or neutral particles because the mammalian cell membrane is negatively charged.62 As a result, positively charged particles are reported to be more likely to destabilize blood cell membranes and cause cell lysis.61 Additionally, the rate of drug release is largely determined by the diameter of the pore. Motivated by the idea, Palma-Chavez et al developed a multistage delivery system by encapsulating PLGA NPs in micron-sized PLGA outer shells.69

Some types of NPs, such as micelles, possess coreshell morphological structures: a core composed of hydrophobic block segments is surrounded by hydrophilic polymer blocks in a shell that stabilizes the entire micelle. The core provides enough space to accommodate compounds, while the shell protects drug molecules from hydrolysis and enzymatic degradation.36 Surface chemical composition largely governs the chemical interactions between NPs and molecules in the body. Appropriate surface coatings can create a defensive layer, protect encapsulated cargo, and affect biological behaviors. Coating with inert polymers like polyethylene glycol (PEG) is the most commonly used method, which hinders interactions with proteins, alters the composition of the protein corona, attenuate NP recognition by opsonins which tag particles for phagocytosis, and extend the half-life of particles.36,70 Additionally, PEG coating helps the therapeutic agents reach ischemic sites, because PEGylated macromolecules tend to diffuse in the interstitial space of the heart.71 Functionalization of gangliosides can further attenuate the immunogenicity of PEGylated liposomes without damaging therapeutic efficacy.72 Removal of detachable PEG conjugates in the microenvironment of the target sites improves capture by cells. Wang and colleagues synthesized PDA-coated tanshinone IIA NPs by spontaneous hydrophobic self-assembly.73 Polyethyleneimine (PEI) is capable of condensing nucleic acid and overcoming hamper of cell membrane. Therefore, modification with PEI is mainly used for the transport of DNA and RNA.74 Of note, despite their inertness, novel NPs composed of metals can also be modified with compounds such as PEG, thiols, and disulfides.48,75 Hydrogels mixed with peptide-coated Au NPs attain greater viscosity than hydrogels mixed with Au NPs.24

Targeted delivery is a primary goal in the development of nanocarriers. Passive targeting is based on enhanced permeability in ischemic heart tissue, which does not meet the needs of clinical application.76 This fact has prompted work on targeting agent modification and magnetic guidance. Conjugation with specific monoclonal antibodies is a feasible method for delivering drug payloads targeted to ischemic lesions. Copper sulfide (CuS) NPs coupled to antibodies targeting transient receptor potential vanilloid subfamily 1 (TRPV1), permit specific binding to vascular smooth muscle cells (SMCs), and can also act as a switch for photothermal activation of TRPV1 signaling.52 In another study conducted by Liu and colleagues, two types of antibodies, binding CD63 (expressed on the surface of exosomes) or myosin light chain (MLC, expressed on injured CMs) are utilized to allow NPs to capture exosomes and accumulate in ischemic heart tissue. These NPs have a unique structure comprising an ferroferric oxide core and PEG-decorated silica shell, which simultaneously enables magnetic manipulation and molecule conjugation via hydrazone bonds.21 Targeted peptides such as atrial natriuretic peptide (ANP),43 S2P peptide (plague-targeting peptide),77 and stearyl mannose (type 2 macrophage-targeting ligand)16 allow NPs to precisely target atherosclerotic tissue and ischemic heart lesions. Modification with EMMPRIN-binding peptide (AP9) has been shown to enable more rapid uptake of micelles by H9C2 myoblasts and primary CMs and to deliver drug payloads targeted to lesions in vivo.78,79 Another strategy for targeted nanocarriers is to produce cell mimetic carriers. Using the inflammatory response as a marker after MI,76 Boada and colleagues synthesized biomimetic NPs (leukosomes) by integrating membrane proteins purified from activated J774 macrophages into the phospholipid bilayer of NPs. Local chronic inflammatory lesions demonstrated overexpression of adhesion molecules, which bound leukosomes efficiently.80

The biocompatibility of NPs is difficult to predict because any interaction with molecules or cells can cause toxic effects. Generally, NPs remain in blood, but can also extravasate from vasculature with enhanced permeability, or accumulate in the mononuclear phagocyte system.81 Important causes of NP-associated toxicity include: oxidative stress injury and cell apoptosis secondary to the production of free radicals, lack of anti-oxidants, phagocytic cell responses, and the composition of some types of particles.61 Hepatotoxicity, nephrotoxicity and any other potential off-target organ damage caused by accumulation of particles, especially those with poor degradability and slow clearance, are also essential to explore in toxicity tests.82 Additionally, the evaluation of evoked immune responses according to the expression of inflammatory factors and stimulation of leukocytes in cell lines and animal models is also important.83

A few studies have reported NP-associated acute and chronic hazards in pharmacological applications, although some of these observations may be contentious. Specifically, aggregation of non-functionalized carbon nanotubes (CNTs) has been observed owing to inherent hydrophobicity of these particles.61 Aside from inflammation and T lymphocyte apoptosis, multi-walled CNTs can rupture cell membranes, resulting in macrophage cytotoxic effects.84,85 Silica NPs induce vascular endothelial dysfunction and promoted the release of proinflammatory and procoagulant factors, mediated by miR-451a negative regulation of the interleukin 6 receptor/signal transducer and activator of transcription/transcription factor (IL6R/STAT/TF) signaling pathway.8688 Metal NPs, such as Au and Ag, can also penetrate the cell membrane, increase oxidative stress and decrease cell viability.89,90 Consequently, exposure to Au may cause nephrotoxicity91 and reversible cardiac hypertrophy.92 El-Hussainy and colleagues observed myocardial dysfunction in rats given alumina NPs.93,94 Nemmar and colleagues investigated the toxicity of ultrasmall superparamagnetic iron oxide nanoparticles (SPIONs) administered intravenously, which resulted in cardiac oxidative stress and DNA damage as well as thrombosis.95 Cell-derived exosomes and a majority of natural polymers are considered relatively safe;83 however, Babiker and colleagues demonstrated that dendritic polyamidoamine NPs compromise recovery from ischemia/reperfusion (I/R) injury in isolated rat hearts.96 The effects of degradation byproducts are also of concern.83 An advantage of the nanoscale size of NPs is that their injection is unlikely to block the microvascular system; however, it remains controversial whether NPs give rise to arrhythmias.97 These factors highlight that examining the biocompatibility of NPs both in vitro and in vivo is a vital component of preclinical or clinical research.

NP toxicity depends on many parameters, including material composition, coating, size, shape, surface charges and concentration.39 For instance, larger particles seem to be more favorable from a toxicology standpoint.83 However, single-walled CNTs are considered more harmful than multi-walled CNTs, due to their smaller size resulting in less aggregation and increased uptake by macrophages.61 Cationic AuNPs are more toxic compared with anionic AuNPs, which appear to be nontoxic.98 Generally speaking, NP-associated toxicity can be lowered by functionalization with nontoxic surface molecules, stabilization and localization in the region of interest by using scaffolds.24,99 The toxicity of CNTs mediated by oxidative stress and inflammation was reduced using these strategies in several studies.24,100 Local application and targeted delivery also enabled dose reduction and concurrently decreased the incidence of adverse effects. Administration of therapeutic agents directly into the infarcted or peri-infarcted myocardium is a conventional approach with a low risk of inducing embolization.

NP is a suitable method for the administration of therapeutic agents in terms of the minimization of side effects, enhanced stability of cargo, and possibility of controlled delivery and release.76 Detailed information on the experimental design and results of the latest studies on the use of NPs as therapeutic vectors are provided in Table 1. Recently, several drugs approved for clinical use as immunosuppressants have been suggested as potentially effective cardioprotective agents. For example, NPs containing cyclosporine A inhibited apoptosis and inflammation in ischemic myocardium by improving mitochondrial function.25,101 Commercial methotrexate also showed minor cardioprotective effects; additionally, when loaded into lipid core NPs, adenosine bioavailability and echocardiographic and morphometric results were all improved a rats model of MI.102 Margulis and colleagues developed a method to fabricate NPs via a supercritical fluids setup, which loaded and transferred celecoxib, a lipophilic nonsteroidal anti-inflammatory drug, into the NPs. These celecoxib-containing NPs alleviated ejection function damage and ventricular dilation by inducing significant levels of neovascularization.103 Furthermore, a series of investigations indicated that drugs used for hypoglycemia (eg pioglitazone, exenatide and liraglutide)104106 and lipid lowering (statins)107 attenuate the progression of post-MI heart failure, and are therefore also potential therapeutic cargoes for NPs in the treatment of MI.

NP systems also offer an alternative method for delivering plant-derived therapeutic agents, most of which belong to traditional Chinese medicine. Its of vital importance because of the criticization on adverse reactions caused by direct injection of such complexes. Cheng and colleagues designed a dual-shell polymeric NP as a multistage, continuous, targeted vehicle of resveratrol, a reactive oxygen species (ROS) scavenger. Due to the severe oxide stress in areas of infarction, the proposed antioxidant-delivery NPs represent a new method to effectively treat MI. These NPs are modified with two peptides, targeting ischemic myocardium and mitochondria, respectively; cardioprotective effects have been confirmed in both hypoxia/reoxygenated (H/R) H9C2 cells and I/R rats.108 In addition, Dong and colleagues also demonstrated that puerarin-SLNs produced smaller areas of infarction in a MI rat model, evaluated by 2,3,5-triphenyltetrazolium chloride (TTC) staining. These particles were modified with cyclic arginyl-glycyl-aspartic acid peptide, a specific targeting moiety to v3 integrin receptors, which are highly expressed on endothelial cells (ECs) during angiogenesis.109 In a recent study, quercetin was loaded into mesoporous silica NPs, which enhanced the inhibition of cell apoptosis and oxidative stress, improving ventricular remodeling and promoting the recovery of cardiac function by activating the janus kinase 2 (JAK2)/STAT3 pathway.110 Similarly, curcuminpolymer NPs, administered by gavage, improved serum inflammatory cytokine levels compared with direct administration of curcumin.111

Translation of novel bioactive agents into clinical practice has been limited, owing to lack of sufficient bioavailability and systemic toxicity.76 Encapsulating small molecules such as 3i-1000 (an inhibitor of the GATA4NKX2-5 interaction),43 TAK-242 (inhibitor of toll-like receptor 4, TLR4)112 and C143 (inhibitor of ERK1/2)113 in NPs promotes myocardial repair after MI without the risk of uncontrolled and off-target adverse effects. Administration of vascular endothelial growth factor (VEGF) causes elevated vascular permeability and tissue edema. The cardioprotective effects of VEGF-loaded polymeric NPs injected either intravenously114 or intramyocardially115 eliminated vascular leakage due to promotion of lymphangiogenesis. Further studies have confirmed these results and add to the evidence that combined delivery of VEGF with other growth factors is recommended, since VEGF primarily drives the formation of new capillaries.116 Furthermore, in line with previous research, similar therapeutic effects have been demonstrated in studies using polymeric NPs loaded with stromal cell derived factor 1 (SDF-1) and insulin-like growth factor 1 (IGF-1).117,118

We also notice that some novel payloads in NPs-based therapy for MI have been studied. For example, deoxyribozyme-AuNP can silence tumor necrosis factor- (TNF-).119 A target that is implicated in irreversible heart damage after MI; its effects are mediated by free radical production, downregulation of contractile proteins, and initiation of pro-inflammatory cytokine cascades. Mesoporous iron oxide NPs containing the hydrogen sulfide donor compound diallyl trisulfide act as a platform for the controlled and sustained release of this therapeutic gas molecule. The application of these NPs at appropriate concentrations, resulted in the preservation of cardiac systolic performance without any observable detrimental effects on homeostasis in vivo.15

With increasing insight into the molecular mechanisms of MI, a particular emphasis on gene therapy has emerged. Gene expression can be modulated by DNA fragments, messenger RNA (mRNA), microRNA (miRNA) and small interfering RNA (siRNA), which thus represent new approaches for treating ischemia. Currently available nucleic acid delivery systems are mainly divided into viral and non-viral systems. However, virus-based approaches are limited by their potential for uncontrollable mutagenesis.36 From a clinical point of view, NP represents a suitable choice as novel non-viral nucleic acid vector, which could feasibly transfect in a stable, targeted, and sustained manner (as shown in Table 2).

Table 2 NPs-Based Nucleic Acid Delivery Systems for Treatment for MI Reported in the Last 7 Years

As a common gene vehicle, plasmids face the risk of being destroyed by DNase and immunoreactivity in the serum, and transduction in non-target organs.120 A recent study by Kim and colleagues aligns with current research trends focused on virus-free therapies, in which carboxymethylcellulose NPs were designed to transfer 5-azacytidine to halt proliferation, and deliver plasmid DNA containing GATA4, myocyte enhancer factor 2C (MEF2C), and TBX5 to induce reprogramming and cardiogenesis of mature normal human dermal fibroblasts.121 In a methodological study, lipidoid NPs were used to successfully deliver pseudouridine-modified mRNA, encoding enhanced green fluorescent protein.122

MiRNAs act as essential regulators of cellular processes through post-transcriptional suppression; increasing evidence reveals miRNAs play critical roles in cardiovascular diseases. An miRNA-transferring platform with self-accelerating nucleic acid release, containing a heparin core and an ethanolamine-modified poly(glycidyl methacrylate) shell, has been constructed and used as an efficient vector of miR-499, which inhibits cardiomyocyte apoptosis.123 Intravenous administration of anionic hyaluronan-sulfate NPs (mean diameter 130 nm) enable the stable delivery of miR-21 mimics, thus modulating the expression of TNF, transforming growth factor (TGF), and suppressor of cytokine signaling 1 (SOCS1). Consequently, these NPs switch the phenotype of macrophages from pro-inflammatory to reparative, promote neovascularization and reduced collagen deposition.124 Interestingly, silencing miR-21 using antagomiR-21a-5p in a nanoparticle formulation has also been shown to reduce expression of pro-inflammatory cytokines in vitro, and attenuate inflammation and fibrosis in mice with autoimmune myocarditis.125 A number of other potentially therapeutic miRNAs have also been successfully transferred to CMs in recent works, including miR-146a, miR-146b-5p, miR-181b, miR-199-3p, miR-214-3p, miR-194-5p and miR-122-5p.126128 Evaluation of angiogenesis, cardiac function, and scar size in these studies indicated that injectable miRNANPs can deliver miRNA to restore injured myocardium efficiently and safely. Yang and colleagues developed an in vivo miRNA delivery system incorporating a shear-thinning hydrogel and NPs characterized by surface presence of miRNA and cell-penetrating peptide (CPP).126 Additionally, angiotensin II type 1 receptor-targeting peptide-modified NPs serve as targeted carriers for anti-miR-1 antisense oligonucleotide, significantly reducing apoptosis and infarct size.129

SiRNAs inhibit gene expression by mediating mRNA cleavage in a sequence-specific manner, highlighting NP-based RNA interference as another viable approach to modulate cellular phenotype and attenuate cardiac failure. Dosta and colleagues demonstrated that poly(-amino ester) particles modified by adding lysine-/histidine-oligopeptides could represent a system for the transfer of siRNA.130 Studies have now revealed that chemokine CC motif ligand 2 (CCL2) and its cognate receptor CC chemokine receptor 2 (CCR2) promoted excessive Ly6Chigh inflammatory monocyte infiltration in infarcted area and aggravate myocardial injury.131 Photoluminescent mesoporous silicon nanoparticles (MSNPs) carrying siCCR2 have been reported to improve the effectiveness of transplanted mesenchymal stem cells (MSCs) in reducing myocardial remodeling after acute MI.131 Targeted transportation and enhanced uptake with minimum leakage improved the efficiency of delivery via NPs, significantly outperforming the control group. Taken together, these studies demonstrate that NPs act as promising drug delivery systems in the treatment of MI.

Myocardial patches and scaffolds, consisting of either bioactive hydrogels or nanofibers, are minimally invasive, relatively localized, and targeted approaches to repair the heart after IHD. Those biomaterials must have an anisotropic structure, mechanical elasticity, electrical conductivity, and the ability to promote ischemic heart repair.132 A variety of NPs have been applied in this field, among which inorganic NPs have been the focus of most research efforts.42 These investigations of inorganic NPs can be divided into four categories based on their effects and the mechanisms involved, which are described in this section.

NPs enhance physical properties and electroconductivity, which is essential for the biomaterials to properly accommodate cardiac cells and subsequently resulted in cell retention, cell-cell coupling and robust synchronized beating behavior. CNTs are able to increase the required physical properties of scaffolds, such as maximum load, elastic modulus, and toughness.133,134 Gelatin methacrylate (GelMA) also has decreased impedance, hydrogel swelling ratio, and pore diameter, as well as increased Youngs modulus when combined with gold nanorods (AuNRs).135 Given this insight, highly electroconductive NPs have been increasingly investigated.34,99 Specifically, Ahadian and colleagues revealed that a higher integrated CNT concentration in gels resulted in greater conductivity.136 Zhou and colleagues verified the therapeutic effects of patches incorporating single-walled CNT for myocardial ischemia, which halted progressive cardiac dysfunction and regenerated the infarcted myocardium.137 Spherical AuNPs have also been shown to increase the conductivity of chitosan hydrogels in a concentration-dependent manner.138 Interestingly, silicon NPs mimic the effects of AuNRs without affecting conductivity or stiffness, as reported by Navaei and colleagues.139

Several studies demonstrate the effects of CNT on CM functions. When CMs are cultured on multi-walled CNT substrates or treated with CNT-integrated patches, these cells show spontaneous electrical activity.34,99,140 Brisa and colleagues functionalized reverse thermal gels with AuNPs, investigating the phenotype of CMs in vitro; the growth of cells with a CM phenotype was observed, along with gap junction formation.141 CMs exposed to AuNR-containing GelMa show higher affinity, leading to packed and uniform tissue structure.135 These conductive scaffolds also facilitate the robustness and synchrony of spontaneous beating in CMs without damaging their viability and metabolic activity.

Combined incorporation of inorganic NPs and cells represents a feasible strategy to promote therapeutic effects. Despite some reports on the cytotoxicity of Au,89,90 no significant loss of viability, metabolism, migration, or proliferation of MSCs in scaffolds containing AuNP is reported. A CNT-embedded, electrospun chitosan/polyvinyl alcohol mesh is reported to promote the differentiation of MSCs to CMs.142 In another approach, Baei and colleagues added AuNPs to chitosan thermosensitive hydrogels seeded with MSCs.138 There was a significant increase in expression of early and mature cardiac markers, indicating enhanced cardiomyogenic differentiation of MSCs compared to the matrix alone, while no difference in growth was observed. Gao et al created a fibrin scaffold, in which cells and AuNPs were suspended simultaneously; these bioactive patches were shown to promote left ventricular function and decrease infarct size and apoptosis in the periscar boarder zone myocardium in swine models of acute MI.97 These studies of AuNP-containing scaffolds demonstrated reduced infarct and fibrotic size, as well as facilitated angiogenesis and cardiac function, which can be attributed at least in part to the enhanced expression of connexin 43 and atrial natriuretic peptide, and activation of the integrin-linked kinase(ILK)/serine-threonine kinase (p-AKT)/GATA4 pathway.49,143,144 Scaffolds containing Ag NPs evoke M2 polarization of macrophages in vitro;145 which may also play a role in cardioprotective action because M2 macrophages are capable of promoting cardiac recovery via the secretion of anti-inflammatory cytokines, collagen deposition, and neovascularization.146

Similarly, CNT also act synergically with poly(N-isopropylacrylamide) scaffolds containing adipose-derived stem cells;147 significant improvement of cardiac function and increased implantation and proliferation of stem cells has been observed with these scaffolds, compared with scaffolds without CNT.147 Selenium NPs148 and titania NPs53 have been shown to improve the mechanical and conductive properties of chitosan patches, promoting their ability to support proliferation and the synchronous activity of cells growing on these patches.

Mounting evidence demonstrates the unique benefits of using cardiac scaffolds with magnetic NPs such as SPIONs; these benefits include, but are not limited to, significant improvements in cell proliferation149 and assembly of electrochemical junctions.150 Given that magnetic manipulation enhances the therapeutic efficacy of iron oxide NPs in cardiac scaffolds, Chouhan and colleagues designed a magnetic actuator device by incorporating magnetic iron oxide NPs (MIONs) in silk nanofibers; this resulted in more controlled drug release properties, as well as the promotion of proliferation and maturation in CMs.151 Magnetic NPs can be used to label induced pluripotent stem cell (iPSC)-derived CMs via conjugation with antibodies against signal-regulatory protein . Zwi-Dantsis and colleagues reported the construction of tailored cardiac tissue microstructures, achieved by orienting MION-labelled cells along the applied field to impart different shapes without any mechanical support.152 However, the interactions between and effects of NPs and cells in scaffolds, and the cardioprotective efficacy of patches in which NP-labelled cells are suspended, require further elucidation.

Polymeric nanomaterials have also been investigated in the context of cardiac bioengineering materials; for instance, water-swollen polymer NPs have been used to prepare nanogels. With a 3D structure containing cross-linked biopolymer networks, nanogels can encapsulate, protect, and deliver various agents.83,153 PDA-coated tanshinone IIA NPs suspended in a ROS-sensitive, injectable hydrogel via PDA-thiol bonds significantly improved cardiac performance, accompanied by inhibition of the expression of inflammation factors in rat model.73 After implanting cryogel patches consisting of GelMa and linked conductive polypyrrole NPs154 or scaffolds of electrospun GelMA/polycaprolactone with GelMA-polypyrrole NPs,155 left ventricular (LV) ejection fraction (EF) has been shown to increase, with a concurrent decrease in infarct size, in MI animal models.

Progenitor or stem cell-based therapy in the form of injections and engineered cardiac patches, discussed in the previous section, has been recognized as a promising strategy to improve the cardiac niche and ameliorate adverse remodeling processes and fibrosis after acute MI.56,156,157 However, poor survival and low engraftment rates for transplanted cells are still major challenges in this field.157 Among possible optimization strategies, combining NPs with stem cell therapy is of great interest (Table 3).

Table 3 Studies Combining NPs and Cell Therapy Reported in the Last 7 Years

Accumulating evidence has shown two main mechanisms for NP-loaded cell therapy in the context of MI treatment. Firstly, various NP types could efficiently improve survival and cell proliferation, modulating differentiation of implanted cells in the ischemic microenvironment.62,158 Specifically, electrically driven nanomanipulators could guide cardiomyogenic differentiation of MSCs: in a previous study, electroactuated gold NPs were administrated with pulsed electric field stimulation, and tube-like morphological alterations were observed, along with upregulation of cardiac specific markers.143 Adipose-derived stem cells that load PLGA-simvastatin NPs promoted differentiation of these cells into SMCs and ECs, and had cardioprotective effects in a mouse model of MI induced by left anterior descending ligation.17 Secondly, engraftment rate is another important factor affecting treatment efficacy in this context.159 Zhang and colleagues designed silica-coated, MION-labelled endothelial progenitor cells; intravenous administration of these cells in a rat model of MI significantly improved cardiac performance, as indicated by echocardiogram, morphological, and histological evidence, and neovascularization. This indicates magnetic guidance may potentially address the problem of low levels of stem cell retention, which has typically been observed.51 In particular, NPs can link the therapeutic cells to injured CMs, thereby promoting cell anchorage and engraftment. To this end, Cheng and colleagues established a magnetic, bifunctional cell connector by conjugating NPs with two antibodies: one against cell determinant (CD)45, which is expressed on bone marrow-derived stem cells, and one against MLC. The magnetic core of this NP also enabled physical enrichment in ischemic heart tissue using external magnets.160 More than one mechanism may be involved in a study. Chen and colleagues fabricated a sustained release carrier of insulin-like growth factor (IGF), a pro-survival agent, via in situ growth of Fe3O4 NPs on MSNPs. In this study, the NPs promoted both the survival and retention of MSCs, and intramyocardial injection of the NP-labeled MSCs was able to ameliorate functional and histological damage without any obvious toxicity in vivo.161 However, SPION labeling does not seem to improve therapeutic efficiency, as demonstrated by Wang and colleagues in a study using hypoxia-preconditioned SPION-labeled adipose-derived stem cells (ASCs).162

Primary criticisms of cell-based therapies include their potential immunogenicity, arrhythmogenicity and tumorigenicity. It is widely accepted that the beneficial effects of cell-based therapy are mainly attributable to paracrine effects rather than directly replenishing lost CMs;56 researchers are therefore investigating of cell-free approaches. Exosomes have attractive properties including stable transport, homing to target tissues or cells, and penetration of biological barriers, as well as being more biocompatible with lower immunogenicity than cell-based approaches. Interestingly, post-MI circulating exosomes serve as important cardioprotective messengers.163,164 Manipulating their biodistribution has proven to be a viable strategy to reduce infarct size, promoting angiogenesis and ejection functions.21 However, from a therapeutic standpoint, the lack of control over endogenous exosome production and cargo encapsulation limits the use of this naturally-present mechanism for therapeutic enhancement. The low purity and weak targeting of natural exosomes are two further obstacles to overcome before clinical application. Strategies to address these include finding robust sources; optimized isolation methods for higher yields, efficiency and purity; and improving therapeutic payloads. These have been systematically summarized in other reviews.165167

AS is considered a low-grade, chronic inflammatory disease, characterized by accumulation and deposition of cholesterol in arteries, as well as remodeling of the extracellular matrix in the intima and inner media.12,168 Inflammation of ECs, proliferation of SMCs, and recruitment of monocytes and macrophages play a critical role in the development of AS. NPs allow for the packaging of large amounts of therapeutic compounds in a compact nanostructure, specifically targeting pathological mechanisms and attenuating atherogenesis. Optimization of the loaded drug and NP target together lead to enhanced efficacy while minimizing side effects.169 In this section, we summarize recent breakthroughs in the order of pathological progression, as shown in Table 4.

Primary prevention refers to control of the risk factors of AS, one of which is hypertension.170 PLA NPs have been shown to improve the efficacy of aliskiren, the first oral direct renin inhibitor and the first in a new class of antihypertensive agents.29 Encapsulation in nanocarriers also renders the application of anandamide viable, which was once limited; recent research revealed that this new therapy could lower blood pressure and LV mass index in rats.171 Similar results were observed in a study in which angiotensinogen was silenced using small hairpin RNA.172 NPs may also help to make more anti-hypertensive drugs available, reduce side effects such as asthma, and lessen the effective dosage by providing sustained drug release over time. The link between AS and diabetes mellitus, which describes a group of metabolic disorders, has also been investigated in numerous studies.173 Possible mechanisms include oxidative stress, altered protein kinase signaling, and epigenetic modifications. Cetin and colleagues successfully constructed NP-based drug delivery systems for the administration of metformin, an oral antihyperglycemic agent with low oral bioavailability and short biological half-life.174 NPs are also promising tools for improving the oral bioavailability of insulin, which is of great interest because oral insulin will significantly increase patients compliance.175,176

The inflammatory hypothesis of AS is now widely established, making selective targeting and accumulation of NPs in inflammatory lesions attractive therapeutic strategies. Targeting macrophages in apoE-/- mice has been shown to result in decreased phagocytosis and suppression of inflammatory genes in lesional macrophages, thus lessening burden of atherosclerotic plaques.177 Tom and colleagues used NPs consisting of high-density lipoprotein (HDL), a known atheroprotective bionanomaterial, as carriers for TNF receptor-associated factor in mice, and observed reductions in both leukocyte recruitment and macrophage activation.178 Both single-walled CNT and HDL-NPs have a favorable safety profile. In a pathological context, activated endothelial tissue expresses more adhesion molecules, such as selectins, than usual. These molecules are thus potential targets for cardiovascular nanomedicine. Glycoprotein Ib (GPIb)179 and biotinylated Sialyl Lewis A (sLeA)69 specifically bind to selectins, leading to the accumulation of conjugated NPs in injured vessels; an in vitro study demonstrated that GPIb-conjugated NPs could bind to target surfaces, where they were taken up by activated ECs under shear stress conditions. In another study, Sager and colleagues simultaneously inhibited five adhesion molecules associated with leukocyte recruitment in post-MI apoE-/- mice. Inflammation in plaque and ischemic heart, rendering acute coronary events and post-MI complications less likely to occur.180 However, targeting inflammatory process may have heterogeneous effects in humans because the targeting moieties and target receptors may be overexpressed in several different pathologic conditions in addition to AS. Oxidation is another factor involved in the development of AS. Upregulation of endothelial nitric oxide synthase (eNOS) leads to vascular construction and other AS-promoting effects. Pechanova and colleagues observed that the application of PLA NPs resulted in larger decreases in NOS than direct administration.29

Aside from these processes, avoiding plaque rupture and thrombosis could be another therapeutic aim. Nakashiro and colleagues showed that delivering pioglitazone via NPs inhibited plaque rupture in apoE-/- mice.181 The integrin 3 is upregulated in angiogenic vasculature, which is ubiquitous in plaque ruptures, which may lead to MI.182 3 integrin-targeted NPs provide a site-specific drug delivery platform that has been shown to successfully stabilize plaques in rabbits.182 Ji and colleagues used NPs composed of albumin with an average diameter of 225.6 nm to deliver a plasmid containing the tissue-type plasminogen activator gene (t-PA); this system plays a role in preventing thrombosis in addition to attenuating intimal thickness and proliferation of vascular SMCs.183 NPs consisting of engineered amphipathic cationic peptide and serine/threonine protein kinase JNK2 siRNA also reduces thrombotic risk, plaque necrotic area, and vascular barrier disorder in mice given the equivalent of a 14-week western diet.184

Innovation and development of therapies based on NPs in recent years has led to significant advances towards complete repair of the injured myocardium following acute MI. Nevertheless, developing clinically relevant solutions remains difficult for several reasons. Firstly, as shown in tables, there is little consistency among studies regarding the characteristics of NPs, their payloads, and their methods of administration, as well as methods used for evaluating cardiac repair. It can be difficult to control characteristics such as the size of the synthesized particles in a narrow range, even within single studies. Such significant heterogeneity can lead to differences in observed results in repeated experiments, or under different conditions. Secondly, although many studies have focused on the health effects of unintentional exposure to NPs by inhalation or ingestion,185,186 most of the studies on medical applications of NPs have not reported on toxicity of NP systems until recently.73 Remarkably, there has not been a consensus on NP-associated adverse effects in existing reports, making assessments of biocompatibility a priority for NP characterization.

NPs have emerged as a powerful tool for controlling cell signaling pathways in regenerative strategies using novel therapeutics and drugs that are unsuitable for direct administration. One advantage of the application of NP systems is the ability to release the drug payload or regulate gene expression in a stable and controlled manner. Therefore, many otherwise serious side effects, such as sudden arrhythmic deaths resulting from persistent and uncontrolled expression of miRNA by viral vectors, may be completely avoided.187 More research is required to develop stable and efficient methods of NP production, improve encapsulation efficiency of drugs, and achieve satisfactory targeting. In particular, a greater focus on investigating NP-based switches, including optical, electrical and magnetic methods, has enabled the regulation of cell signaling, exemplified by the development of a CuS NP-based photothermal switch.52 Optimizing tissue engineering scaffolds containing conductive NPs is a promising strategy for the protection of the myocardium after ischemia by mimicking the myocardial extracellular matrix. Improvements in understanding of cardiac repair mechanisms, and how these biomaterials may interfere with them, is therefore urgently needed. Furthermore, heart repair is complex and involves many processes, including apoptosis, angiogenesis, inflammatory infiltration, and fibrosis. Therefore, novel treatments should be designed using NP-based integrative strategies based on these multiple different mechanisms. However, its important to highlight that synergistic effects of different drug payloads, NPs, and NPcell combined strategies should be addressed, as not all may be compatible with one another. Future research should focus on these aspects to translate NP-based therapeutic strategies for MI into practical and effective clinical use.

Mantarray: Scalable Human-relevant 3D Engineered Cardiac and Skeletal Muscle Tissues for Therapeutics Discovery Upcoming Webinar Hosted by Xtalks -...

Today is International Heart Day, and Cosmos is looking back on the stories that make our hearts flutter.

Scientists have taken another step in the quest to create a Google map of the human body by putting together a detailed cellular and molecular map of the healthy heart.

An international team analysed almost half a million individual cells and cell nuclei from six different regions of the heart, obtained from 14 organ donors whose hearts were healthy but unsuitable for transplantation.

The result is theHeart Cell Atlas, which, shows the huge diversity of cells and reveals heart muscle cell types, cardiac protective immune cells and an intricate network of blood vessels. It also predicts how the cells communicate to keep the heart working.

Sometimes, the heart just stops for no perceivable reason. Sudden cardiac arrest (SCA) is a prevalent hidden killer, even for younger people: 40% of those who die from SCA are under 50 years old.

SCA is not as rare as we would like it to be, says cardiologist Elizabeth Paratz, whos undertaking her PhD at the Baker Heart and Diabetes Institute, Melbourne. In the last year in Victoria, 750 young people under 50 have suffered an SCA. This is almost exactly five times the road toll over the same time in this age group, yet we hear a lot more publicity about road fatalities in young people.

Paratz is researching the prevalence and causes of SCA, as well as looking at ways to diagnose it better. There are multiple causes of SCA, and theyre hard to pinpoint in young people.

The controversial use of stem cells to help patients recover from a heart attack may work, but not because it grows new heart muscle.

Research in mice has found that injecting stem cells into the heart triggers an immune response that makes the scar stronger and the heart beat more forcefully.

Thestudy, published in the journalNature, suggests the current practice of injecting stem cells into a patients blood may not be optimal: direct injection into the heart could be more effective.

In a preclinical trial on a beating human heart, researchers have found that a drug candidate developed from the venom of the worlds deadliest spider, the funnel web, may hold promise for heart attack treatment and transplants.

The researchers, led by Meredith Redd of the University of Queensland (UQ), and Sarah Scheuer of Victor Chang Cardiac Research Institute, tested a protein called Hi1a, found in the Fraser Island (Kgari) funnel web venom, on a beating heart that had been exposed to heart attack stresses.

After a heart attack, blood flow to the heart is reduced, resulting in a lack of oxygen to heart muscle, says Nathan Palpant of UQ, corresponding author of the paper.

The lack of oxygen causes the cell environment to become acidic, which combine to send a message for heart cells to die.

The Hi1a protein from spider venom blocks acid-sensing ion channels in the heart, so the death message is blocked, cell death is reduced, and we see improved heart cell survival.

The Chinese Finger Trap a tubular braided novelty beloved by kids and pranksters around the world provided the inspiration for a nifty bit of biotech that looks set to save sick kids a whole lot of heartache. Literally.

Pedro del Nido from Boston Childrens Hospital in the US heads a team that has designed a proof-of-concept device that promises to dramatically cut down on surgery for children with certain types of heart defects.

At present, kids with defective mitral and tricuspid heart valves must undergo surgery in which a corrective implant is installed. The problem, however, is that children grow: the heart increases in size, and requires at least one, and often several, further surgical interventions so that a correspondingly larger implant can be installed.

Needless to say, these repeated bouts of open-heart surgery are extremely traumatic and disruptive.

Now, however, Nido and Karp may have come up with an elegant and clever solution: an implant that grows with the organ.

Five Heart Stories For International Heart Day - Cosmos

SYDNEY, Oct. 5, 2021 /PRNewswire/ -- Clinical stage drug development company Pharmaxis Ltd (ASX: PXS) today announced further positive results of data analysis from a phase 1c clinical trial (MF-101) studying its drug PXS-5505 in patients with the bone marrow cancer myelofibrosis for 28 days at three dosage levels.

Assessment with Pharmaxis' proprietary assays of the highest dose has shown inhibition of the target enzymes, LOX and LOXL2, at greater than 90% over a 24-hour period at day 7 and day 28. The trial safety committee has reviewed the results and having identified no safety signals, has cleared the study to progress to the phase 2 dose expansion phase where 24 patients will be treated at the highest dose twice a day for 6 months.

Pharmaxis CEO Gary Phillips said, "We are very pleased to have completed the dose escalation phase of this study with such clear and positive findings.We will now immediately progress to the phase 2 dose expansion study where we aim to show PXS-5505 is safe to be taken longer term with the disease modifying effects that we have seen in the pre-clinical models. The trial infrastructure and funding is in place and we are on track to complete the study by the end of 2022."

Independent, peer-reviewed research has demonstrated the upregulation of several lysyl oxidase family members in myelofibrosis.The level of inhibition of LOX achieved in the current study at all three doses significantly exceeds levels that caused disease modifying effects with PXS-5505 in pre-clinical models of myelofibrosis with improvements in blood cell count, diminished spleen size and reduced bone marrow fibrosis. LOXL2 was inhibited to a similar degree and based on pre-clinical work such high inhibition is likely replicated for other LOX family members (LOXL1, 3 and 4).[1] Study data can be viewed in the full announcement.

Commenting on the results of the trial, Dr Gabriela Hobbs, Assistant Professor, Medicine, Harvard Medical School & Clinical Director, Leukaemia, Massachusetts General Hospital said, "Despite improvements in the treatment of myelofibrosis, the only curative therapy remains an allogeneic stem cell transplantation, a therapy that many patients are not eligible for due to its morbidity and mortality. None of the drugs approved to date consistently or meaningfully alter the fibrosis that defines this disease. PXS-5505 has a novel mechanism of action by fully inhibiting all LOX enzymes. An attractive aspect of this drug is that so far in healthy controls and in this phase 1c study in myelofibrosis patients, the drug appears to be very well tolerated. This is meaningful as approved drugs and those that are undergoing study, are associated with abnormal low blood cell counts. Preliminary data thus far, demonstrate that PXS-5505 leads to a dramatic, >90% inhibition of LOX and LOXL2 at one week and 28 days. This confirms what's been shown in healthy controls as well as mouse models, that this drug can inhibit the LOX enzymes in patients. Inhibiting these enzymes is a novel approach to the treatment of myelofibrosis by preventing the deposition of fibrosis and ultimately reversing the fibrosis that characterizes this disease."

The phase 1c/2a trial MF-101 cleared by the FDA under the Investigational New Drug (IND) scheme aims to demonstrate that PXS-5505, the lead asset in Pharmaxis' drug discovery pipeline, is safe and effective as a monotherapy in myelofibrosis patients who are intolerant, unresponsive or ineligible for treatment with approved JAK inhibitor drugs. Trial sites will now open to recruit myelofibrosis patients into the 6-month phase 2 study in Australia, South Korea, Taiwan and the USA.

An effective pan-LOX inhibitor for myelofibrosis would open a market that is conservatively estimated at US$1 billion per annum.

While Pharmaxis' primary focus is the development of PXS-5505 for myelofibrosis, the drug also has potential in several other cancers including liver and pancreatic cancer where it aims to breakdown the fibrotic tissue in the tumour and enhance the effect of chemotherapy treatment.

About PXS-5505

PXS-5505 is an orally taken drug that inhibits the lysyl oxidase family of enzymes, two members LOX and LOXL2 are strongly upregulated in human myelofibrosis. In pre-clinical models of myelofibrosis PXS-5505 reversed the bone marrow fibrosis that drives morbidity and mortality in myelofibrosis and reduced many of the abnormalities associated with this disease. It has already received IND approval and Orphan Drug Designation from the FDA.

Myelofibrosis is a disorder in which normal bone marrow tissue is gradually replaced with a fibrous scar-like material. Over time, this leads to progressive bone marrow failure. Under normal conditions, the bone marrow provides a fine network of fibres on which the stem cells can divide and grow. Specialised cells in the bone marrow known as fibroblasts make these fibres.

In myelofibrosis, chemicals released by high numbers of platelets and abnormal megakaryocytes (platelet forming cells) over-stimulate the fibroblasts. This results in the overgrowth of thick coarse fibres in the bone marrow, which gradually replace normal bone marrow tissue. Over time this destroys the normal bone marrow environment, preventing the production of adequate numbers of red cells, white cells and platelets. This results in anaemia, low platelet counts and the production of blood cells in areas outside the bone marrow for example in the spleen and liver, which become enlarged as a result.

Myelofibrosis can occur at any age but is usually diagnosed later in life, between the ages of 60 and 70 years. The cause of myelofibrosis remains largely unknown. It can be classified as either JAK2 mutation positive (having the JAK2 mutation) or negative (not having the JAK2 mutation).

Exosome therapeutic Market Report- Trends Key Programs Analysis and Competitive Landscape and Forecast 2028 Amite Tangy Digest - Amite Tangy Digest

Shahid Akhter, editor, ETHealthworld spoke to Dr. Dinesh Bhurani, Director, Department of Hemato-Oncology & Bone Marrow Transplant, Rajiv Gandhi Cancer Institute and Research Centre, to know about the progress of NPRD and the challenges associated with blood stem cell transplants.

How do you think the National Policy for Rare Diseases will impact the treatment of patients suffering from rare blood disorders? Will it help reduce the lag that we often see in policy and practice when it comes to healthcare systems?National Policy on Rare Diseases is a step-in right direction and must be welcomed by the Indian medical fraternity. It not only recognizes rare diseases for the first time in India but also has brought forward the possibility of affordable treatment for life-threatening rare diseases which were not previously covered under the national health program. The policy advocates access for treatment through center of excellences, crowd funding and financial assistance.

The NPRD in a bid to enable patients suffering from rare blood disorders has laid emphasis on the option of one-time curative treatment through hematopoietic stem cell transplant for diseases such as Severe Combined Immunodeficiency (SCID), Chronic Granulomatous disease, Wiskott Aldrich Syndrome, Osteopetrosis, and Fanconi Anaemia. By committing to provide a Rs. 20 lakhs cover for the one-time treatment cost of diseases falling under Group 1 through the umbrella scheme of Rashtriya Arogya Nidhi, the NPRD has attempted to provide coverage to almost 40 per cent of the population who are eligible under the Pradhan Mantri Jan Arogya Yojana. The NPRD as a policy that advocates affordable and accessible healthcare and has the potential to lead to the creation of a conducive healthcare ecosystem whereby multisectoral partnerships can collaboratively work towards reduction in the lag between policy and practice often seen otherwise, thereby leading people to live healthier and fuller lives.

Another reason for low number of donors in India is the misconception that stem cell donation comes with a cost to donor. This idea is completely misplaced and untrue as the cost of procedure starting from sample collection, donation and travel is free of cost, and covered under the cost of treatment of a patient for whom the donation is needed. Added to this is the fact that the number of organizations working in the country in the space of blood stem cell transplant is limited at best, thus awareness generation as compared to other health issues is nominal. However, the situation is gradually evolving and ICMR in its 2021 guidelines has gone on to recognize seven registries across the country as active stakeholders in this ecosystem. This recognition by ICMR will hopefully lead to greater awareness generation.

For blood stem cell transplant knowledge is key in establishing patient donor linkage, and by storing the requisite information with them, these registries do just that. Technology is a tool that has been successfully leveraged by stakeholders in the ecosystem to establish linkages. The Hap- E Search is one such tool that has been used by hospitals in the country to find donor matches for their patients. This software is perhaps one of the most enabling tools available to us in the ecosystem, as it helps find HLA matches not just in the country but across the world. This software is now being used by many government hospitals like AIIMS, Delhi and PGIMER Chandigarh. Once the matching donor is found via the HAP-E Search, the donor is encouraged to make the donation, provided counselling and support to donate blood stem cells, and post donation the stem cells are transported to the patients location.

The NPRD proposed crowdfunding and PPP models to ensure more patients availing treatment for rare diseases. How beneficial do you think such partnerships can be to enable blood stem cell transplant ecosystem?Treatment for rare diseases has been found to be expensive across the world. It is thus that despite stem cell transplants being a proven effective solution in the case of some blood disorders, affordability continues to be a challenge for patients and their families. With treatment costs ranging anywhere between Rs. 15-45 lakh, it remains out of reach for most patients in the country. Also, blood disorders, classified as rare, have limited infrastructure in health systems, networks, and subsidies for patients to access treatments are few. In such a scenario, crowdfunding is definitely a feasible option for patients that would ensure that they do not have to forego treatment due to a paucity of resources.

As per the NPRD, the money raised through crowdfunding would directly get credited to the treatment centre thus ensuring that there is adequate linkage. Further, the public private partnership model suggested by the government has enabled it to avail the support of non- governmental and not-for- profit agencies present in the country. This is truly commendable as not only will this ensure more patient donor linkage in the blood stem transplant ecosystem but will also lead to greater awareness generation and registrations of donors as well. One significant organization that has already partnered with the government in this arena is the DKMS BMST Foundation India. With over 50,000 blood stem cell donors registered with them, this organization has been steadily working towards enabling the ecosystem. In the case of rare diseases, it is imperative that stakeholders do not work in isolation and the government working alongside the private can lead to greater hope for many patients with greater amenities and facilities for treatment being made accessible to them.

Lack of awareness about blood stem cell donation is one of the leading causes for low number of donors in In.. - ETHealthworld.com

Trained as a chemist, biophysicist, internist, and cardiologist, Mark Yeager is eager to propel the Frost Institute for Chemistry and Molecular Science into a leading research center.

Even in his youth Mark Yeager could picture the door to his future. Scuffed, chipped, and almost black from layers of varnish, the old, wooden door had a frosted window with five words stenciled in glossy black: Laboratory of Dr. Mark Yeager.

Yet Yeager, the inaugural executive director of the University of Miamis Frost Institute for Chemistry and Molecular Science (FICMS), is quite happy that his new lab in the 94,000-square-foot building slated to open late next year wont even have a door. The $60 million facilitys open floor plan was designed to encourage the free flow of people and ideasand help transform the University into one of the worlds premier research centers for improving the health of humans and that of our planet.

That is the vision, but its not a fantastical vision, said Yeager, a distinguished biophysicist and cardiologist whose top priority is attracting a diverse and elite group of scientists as the institutes first faculty. It is achievable, and it will happen because the University has not wavered in its commitment to elevate STEM (science, technology, engineering, and mathematics) to advance scientific discovery. Theres something going on here thats organic and alive and excitingand Im thrilled to be part of it.

Yeager, whose own groundbreaking research focuses on the molecular causes of heart disease and viral infections, trained as a chemist at Carnegie-Mellon University, as a physician and biophysicist at Yale University and as an internist and cardiologist at Stanford University. He spent two decades at Scripps Research in California, where he established his first independent laboratory, served as the director of research in cardiology, and helped launch the Skaggs Clinical Scholars Program in Translational Research. He has also served as a consultant and scientific and clinical advisor to several biotech companies.

Now he is transitioning to the University from the University of Virginia School of Medicine (UVA), where he chaired the Department of Molecular Biophysics and Biochemistry for nearly a dozen years and helped establish the Sheridan G. Snyder Translational Research Building. At UVA, he also established one of the nations five regional centers for cryo-electron microscopy (cryoEM)the technique he advanced for flash-freezing, imaging, and studying proteins and other macromolecules in their near-natural state.

It is exciting to see the progress being made on the evolution of our Frost Institutes, starting with Data Science and Computing and now the emergence of Chemistry and Molecular Science. We are fortunate to have Mark overseeing our Frost Institute for Chemistry and Molecular Science and working across the entire institutionhis interdisciplinary knowledge and perspective on chemistry are essential for our success, said Jeffrey Duerk, executive vice president for academic affairs and provost. Mark brings a wealth of knowledge and experience to the University of Miami and we are looking forward to his impactful leadership continuing as we move forward.

Yeager said he knew he was making the right career move on his first visit to the University last November. Although the COVID-19 pandemic had curtailed in-person learning and suspended new construction, he heard the unmistakable sound of heavy equipment as he walked past the royal palms and fountain at the end of Memorial Drive, where the five-story FICMS now stands.

I could see an excavation area and heard a cacophony of construction noise where I had a hunch the institute should be, he recalled. That told me that the University was all in. They had made this commitment to fortify STEM and to do transformational science and nothing was going to stop them. In spite of the pandemic, it was all systems go.

The Universitys longtime benefactors, Phillip and Patricia Frost, enabled that commitment in 2017, when they announced their landmark $100 million gift to establish the Frost Institutes for Science and Engineering, now a key initiative of the Roadmap to Our New Centurythe strategic plan guiding the University toward its centennial mark. The umbrella organization for a group of multidisciplinary research centers patterned after the National Institutes of Health and its network of affiliated institutes, the Frost Institutes were envisioned to translate interdisciplinary research into solutions for real-world problems.

Though Yeager officially started his new role on June 1, he has been heavily involved in planning the FICMS' interior for months. He recently placed a $20 million order to equip the facility with five different electron microscopy instruments that chemists, molecular scientists, and engineers will use to explore the molecular structure of exquisitely beam-sensitive soft materials like proteins, hard materials such as metal alloys, as well as nanomaterials comprised of soft and hard components. Along with the buildings state-of-the-art technology and the Universitys research infrastructure, hes confident its location in the heart of the Coral Gables campus will help him recruit a diverse and elite group of scientists who are exploring challenging avenues of impactful researchsomething he has been driven to do almost his entire life.

An occasional songwriter, guitar player, and jogger who in his younger days ran 18 marathons, Yeager was always fascinated by scientific discoveries that illuminated unknown and unseen worlds. A child of the Sputnik era who began entering science fairs in junior high, he began forging his own career as a physician-scientist while in high school in Colorado Springs, Colorado, where his father, an agricultural economist, settled his family after a number of job-related moves.

Inspired by an experiment in Scientific American magazine, he convinced physicians in the therapeutic radiology department at Penrose Hospital to irradiate his fruit flies so he could compare the effects of administering different doses of radiation on their eye pigments. Delivered in Styrofoam cups, his experiments on what is now called dose fractionationand used to reduce tissue damage during cancer treatmentswon him first place in the U.S. Department of Agricultures 1967 International Science Fair and a research stint in an insect toxicology lab in Berkeley, California.

The following summer, when Yeager returned to Penrose Hospital to work as an orderly, he realized that he loved patient care as much as laboratory research and began plotting how he could pursue both careers.

I just got incredible satisfaction from helping patients get out of bed and into a wheelchair, transfer to a gurney, learn to use crutches, recalled Yeager, who joins the University as one of its 100 Talents for 100 Years, a Roadmap initiative to add 100 new endowed chairs to the faculty by the Universitys 2025 centennial. But I also loved chemistry. I loved physics. I loved too many things.

After earning his undergraduate degree in chemistry from Carnegie-Mellon, he was accepted to the Medical Scientist Training Program at Yale University, where, along with his medical degree, he earned his masters degree and doctorate in molecular biophysics and biochemistry. There, he encountered the first of many trailblazing scientists, including two future Nobel laureates, who would influence his lifes work. His Ph.D. advisor, Lubert Stryer, was particularly influential. Stryer authored a premier textbook of biochemistry, pioneered fluorescence-based techniques to explore the motions of biological macromolecules, and made fundamental discoveries on the molecular basis of vision. Yeagers graduate work on rhodopsin, a photoreceptor membrane protein, triggered his fascination with elucidating the molecular bases for such diseases as sudden cardiac death, heart attacks, HIV-1, and other viral infections.

Yeager completed his medical residency and specialized fellowship training in cardiovascular medicine at Stanford University Medical Center, where he managed the pre- and post-operative care of heart transplant patients and wrote 13 chapters in the book Handbook of Difficult Diagnoses.

He also continued exploring cellular biology in the laboratory of Nigel Unwin, who had collaborated with future Nobel laureate Richard Henderson to pioneer the use of cryoEM to determine the molecular structure of membrane proteinsand inspired Yeagers groundbreaking research on gap junction channels. The electrical conduits that connect every cell in the body to its neighbor, gap junction channels play a critical role in maintaining the normal heartbeat.

That research, which Yeager continued at Scripps and at UVA, explained how gap junction channels behave in their normal state, and during an injured state, such as a heart attack. His quest to answer another question particularly relevant todayhow viruses enter host cells, replicate, and assemble infectious particlesis exemplified by his breakthrough research on the assembly, structure, and maturation of HIV-1, the virus that causes AIDS.

Today, those insights, which Yeager humbly calls a few bricks in the edifice of science, hold important clues for developing new, more effective therapies to prevent HIV-1 infection, repair injured tissue, and treat cancer and cardiovascular diseasethe kind of impactful research that the FICMS was designed to advance with collaborative partners across the University, and beyond.

As a pioneer in the field of cryo-transmission electron microscopy, a forefront technology in materials and biological research, Marks expertise and knowledge will position the University as aleader in these cutting-edge fields, said Leonidas Bachas, dean of the College of Arts and Sciences who served as the initial interim director of the FICMS. We look forward to having him lead the Frost Institute for Chemistry and Molecular Science as we continue to advance the sciences, innovate, and expand research collaborations with our faculty and industry partners.
