UPDATE:

SPOKANE, Wash. -- Life-saving cells for alocal father of six are on their way to him from Poland. His family has been panicked after a travel ban was put in place by the Polish Government. They say they were told the status of the transport was stalled, and with time slipping away, they needed immediate action.

Jared Weeks was diagnosed withAcute Myeloid Leukemia back in October. His wife Janet contacted 'Help Me Hayley' on Saturday. On Sunday morning, Janet got word that the cells were on their way. She reached out to many government officials and is still trying to sort how and who helped make this happen for her husband.

"I heard that relief in (my husband's) voice and that's all I needed," she said. "I'm so thankful to everyone who shared the story, sent us prayers. I felt it. I really did. People are so overwhelmingly beautiful."

Janet says her husband will have the stem-cell transplant on Tuesday.

"I will be traveling over to Seattle on Monday evening to be there for his 're-birthday,'" she said of the procedure. "I'm so grateful."

SPOKANE, Wash. -- A local father of six desperately needs help receiving life-saving cells provided by an overseas donor. His family says his life depends on it.

His wife Janet sent our Hayley Guenthner this 'Help Me Hayley' request:

"Dear Help Me Hayley,

My children and I are desperate to save my husband. He was diagnosed with Acute Myeloid Leukemia on 10/15/2019 (on his 42nd birthday of all days) since then he has been in the hospital. At the beginning of February we started our journey to the west side of the state to be under the care of Seattle Cancer Care Alliance and to make a long story short, we are now in the transplant stage of his disease.

My husband, Jared Weeks, went inpatient to the University of Washington Medical Center (UWMC) on behalf of the Seattle Cancer Care Alliance. He started his myeloablative chemo regimen on March 10th with the expectation of receiving an Unrelated Allogeneic Peripheral Blood Stem Cell transplant. He had the highest dose of chemotherapy to eliminate his disease and replace his immune system with a 38-year-old female peripheral blood stem cell donation from Poland. Because of the travel ban put in place by the Polish Government in response to the outbreak of the Novel COVID-19 virus, it is becoming impossible to transport these LIFE-SAVING cells that have been extracted from my husband's donor and brought back to the United States. I have left messages for Senator Cathy McMorris-Rodgers, Governor Jay Inslee, Mayor Woodward and Senator Maria Cantwell. I was able to speak personally with State Senator Shelly Short who is passing on this to some of her contacts in the cabinet. I reached out to the Polish Government agency handling the travel ban restrictions and have spoken with an Overseas Citizen Services Safety Officer out of Krakow Poland at the US Embassy-State Department. The travel ban has been put in place but I have been told that roads are still open as well as trains and planes, but as of midnight tonight (not sure if our time or their time) the borders will be closed until March 25th, and maybe extended depending on the COVID-19 outbreak. The cells have been collected from the donor and we are desperate to get them here. Please help us!! God help us.

My husband, Jared Weeks, was diagnosed with Acute Myeloid Leukemia on October 15, 2019 and is in DIRE need of these stem cells to survive.

We need some assistance from the "powers that be" to get these life-saving stem cells to my husband in Washington State ASAP.

His life depnds on it."

There have many people offering to test to see if they are a local match for Jared. Unfortunately, the family doesn't have the kind of time required to find a new donor.

"They would need to go to bethematch.org , however, it is too late in the game to be a donor for Jared but there are hundreds of others that need this life-saving donation as well," Janet said. "The HLA TYPING that is done can take weeks to complete and for Jared, we don't have that kind of time."

Janet is currently in Spokane with their children. She said she is doing everything she can to stay strong for her husband.

"(Jared) is one heck of a dad," Janet said. "He is hardworking, loves the outdoors, fishing, boating and taking his kids on adventures. He is amazing to us and is the center of gravity for our rather large family. He has been through hell and back with this cancer, and is still trusting God completely."

Seattle Cancer Cancer Care Alliance sent KHQ a statement on Jared and other cancer patients relying on life-saving bone marrow transplants during the COVID-19 outbreak.

"The COVID-19 outbreak is an evolving and fluid situation, and the global medical community is collaborating to address the needs of people who are relying on bone marrow transplants for their treatment and survival.

"Seattle Cancer Care Alliance is evaluating every patient who is currently connected with an international or USA-based donor to ensure we have an alternative solution for their treatment should the need arise.

"We are committed to continuing to coordinate with the National Marrow Donor Program and the World Marrow Donor Association, along with donor representatives in various countries, to prevent potential disruptions of critical medical transport so that every cancer patient has access to the life-saving treatment they need.

"SCCA is dedicated to providing the highest-quality cancer care, and we take that responsibility very seriously. We continue to work very closely with our alliance partners -Fred Hutch, UW Medicine and Seattle Childrens- and sharing our approach and best practices with other transplant centers around the country who may face similar unprecedented challenges."

An HIV patient recovered with a stem cell transplant. He became the second patient in the world to recover from this disease.

an HIV patient who received a stem cell transplant is now cured. He has become the second patient in the world to recover from the disease, his doctors announced Tuesday, March 10.

Almost ten years after the first confirmed case of an HIV patient who managed to get rid of it, this second case, known as the London patient, has shown no signs of the virus for 30 months, according to the results published in the journal The Lancet HIV.

In March 2019, Professor Ravindra Gupta, of the University of Cambridge, announced that this man diagnosed with HIV in 2003 was in remission, having shown no sign of the virus for 18 months. The doctor had however called for caution, insisting on the term of remission and not healing, asking for more time.

We suggest that our results represent a cure for HIV

A year later, his team took this step. We suggest that our results represent a cure for HIV, they write, after testing samples of blood, tissue, sperm. We tested a fairly considerable number of places where the virus likes to hide and practically everything was negative, apart from a few fossil remains of non-active virus, Pr Gupta told AFP. It is hard to imagine that all traces of a virus that infects billions of cells have been eliminated, he said.

Like the Berlin patient, the American Timothy Ray Brown considered cured in 2011, this London patient underwent a bone marrow transplant to treat blood cancer, and thus received stem cells from donors carrying a rare genetic mutation that prevents HIV from taking hold, CCR5.

Scientists point out that the procedure used for the two recovered patients is very cumbersome and risky, asking ethical questions, as Professor Gupta points out.

Is the London patient really healed? Asked Sharon Lewin of the University of Melbourne. The data () is of course exciting and encouraging, but in the end, only time will tell, she noted, saying it would take more than a handful of HIV-cured patients to assess the likelihood of a late and unexpected resumption of virus replication .

Almost 38 million people are living with HIV worldwide, but only 62% are receiving triple therapy. Nearly 800,000 people died in 2018 from HIV-related conditions. The emergence of drug-resistant forms of HIV is also a growing concern.

Friend of Owner//Driver and owner of the iconic Filthy White 4000 we covered last year, Mick Moo Lake, was diagnosed with cancer on Christmas Eve.

Mick and Mel Lake, with 'Filthy'

Since the devastating news, Mick and his wife Mel have been struggling to balance treatment and operating their business Truckin Stainless setting up a GoFundMe page to help cover the costs of hospital care.

Mick has Double Myeloma, a form of cancer that develops from plasma cells in the bone marrow, and has been receiving ongoing treatment since New Years Eve.

In 10 weeks Mick is having a Stem Cell Blood Transfusion, which will put him out of work for at least a month and will put significant strain on his business and familys livelihood.

At the time of writing, the GoFundMe page has raised $3,195 and Mick and Mel say the money will go towards covering the cost of treatment and help keep their business afloat.

Mick has been working through the treatment, where possible, to keep Truckin Stainless kicking along with the help of his good mate Steve who travelled down from Mackay to help lighten the load.

"He heard about what was going on when he was down here at the time, and he decided to stay and help while I was getting treatment," Mick says.

"Ive been working through it, going to hospital for treatments then back to the workshop - i havent stopped.

"In respect of all the wonderful people that have had to endure this terrible disease, we understand that asking for donations seems a bit steep, but if you would like to donate please do so, or think to donate to any cancer foundation," he says.

SEATTLE--(BUSINESS WIRE)--NanoSurface Biomedical announced today that it has executed an exclusive IP license agreement related to innovative heart-on-chip technology developed by researchers at the University of Washington (UW). An experimental system built from the same heart-on-chip technology was launched into space on Friday, March 6, 2020 at 11:50 PM EST aboard SpaceX's 20th resupply mission to the International Space Station (ISS) as part of the Tissue Chips in Space initiative conducted in partnership between the National Center for Advancing Translational Sciences (NCATS) and the ISS U.S. National Laboratory (ISS National Lab). NanoSurface will commercialize the heart-on-chip platform for use by pharmaceutical companies in preclinical drug development.

The heart-on-chip system will spend 30 days aboard the ISS as part of a series of experiments intended to study the effects of microgravity on human cells and tissues. In space we are using the heart-on-chip system in microgravity conditions to help improve our understanding of the aging process and cardiac biology, but this heart-on-chip system also has enormous potential for accelerating the discovery of new medicines back here on Earth, said Deok-Ho Kim, an Associate Professor of biomedical engineering and medicine at Johns Hopkins University, the principal investigator for the heart-on-chip experiment aboard the ISS, and the scientific founder of NanoSurface Bio.

The heart-on-chip platform uses three-dimensional engineered cardiac tissues (3D ECTs) grown from human cardiomyocytes, or beating heart cells, derived from induced pluripotent stem cells (iPSCs). As the 3D ECTs beat, researchers can measure the amount of force generated by each contraction, and then evaluate how that force changes after treating the tissues with candidate drugs. 3D ECTs can be made from cells from either healthy individuals or individuals with diseases, offering great promise in predictive preclinical testing of candidate drugs for safety and efficacy.

I am incredibly excited that the talented team at NanoSurface will be carrying this technology forward for use in the drug development industry, said Nathan Sniadecki, one of the inventors of the heart-on-chip technology and a professor of mechanical engineering at UW. Last year, Professor Sniadecki joined NanoSurfaces board of scientific advisors to guide the commercial development of the technology.

NanoSurface Bios execution of this exclusive license adds significant value to the portfolio of IP it has already licensed from researchers at UW. It is well recognized that the drug development process is extremely slow and expensive. At NanoSurface we are eager to develop technologies that enable the use of human iPSC-derived cells and tissues in preclinical drug development, ultimately leading to better prediction of how drugs will affect patients in the clinic, lowering costs, and speeding life-saving medicines to market, said NanoSurface CEO Michael Cho.

About NanoSurface Biomedical

NanoSurface Biomedical is a biotechnology company based in Seattle, WA that develops stem cell-based assay technologies to accelerate drug development. NanoSurfaces structurally matured cardiac tissue models, assay instruments, and discovery services leverage human stem cell technology to help pharmaceutical companies predictively assess the safety and efficacy of candidate drugs early during preclinical development. NanoSurfaces mission is to help bring life-saving medicines to market in less time and at lower cost. To learn more, visit http://www.nanosurfacebio.com.

Immune cells by fluorescence microscopy: Blood stem cells remember a previous attack and produce more immune cells like these macrophages to fight a new infection. Credit: Sieweke lab/CIML

These findings should have a significant impact on future vaccination strategies and pave the way for new treatments of an underperforming or over-reacting immune system. The results of this research are published in Cell Stem Cell on March 12, 2020.

Stem cells in our bodies act as reservoirs of cells that divide to produce new stem cells, as well as a myriad of different types of specialized cells, required to secure tissue renewal and function. Commonly called blood stem cells, the hematopoietic stem cells (HSC) are nestled in the bone marrow, the soft tissue that is in the center of large bones such as the hips or thighs. Their role is to renew the repertoire of blood cells, including cells of the immune system which are crucial to fight infections and other diseases.

Until a decade ago, the dogma was that HSCs were unspecialized cells, blind to external signals such as infections. Only their specialized daughter cells would sense these signals and activate an immune response. But work from Prof. Michael Siewekes laboratory and others over the past years has proven this dogma wrong and shown that HSCs can actually sense external factors to specifically produce subtypes of immune cells on demand to fight an infection. Beyond their role in an emergency immune response, the question remained as to the function of HSCs in responding to repeated infectious episodes. The immune system is known to have a memory that allows it to better respond to returning infectious agents. The present study now establishes a central role for blood stem cells in this memory.

We discovered that HSCs could drive a more rapid and efficient immune response if they had previously been exposed to LPS, a bacterial molecule that mimics infection, said Dr. Sandrine Sarrazin, Inserm researcher and senior-author of the publication. Prof. Michael Sieweke, Humboldt Professor at TU Dresden, CNRS Research Director and last author of the publication, explained how they found the memory was stored within the cells: The first exposure to LPS causes marks to be deposited on the DNA of the stem cells, right around genes that are important for an immune response. Much like bookmarks, the marks on the DNA ensure that these genes are easily found, accessible and activated for a rapid response if a second infection by a similar agent was to come.

The authors further explored how the memory was inscribed on the DNA, and found C/EBP? to be the major actor, describing a new function for this factor, which is also important for emergency immune responses. Together, these findings should lead to improvements in tuning the immune system or better vaccination strategies.

The ability of the immune system to keep track of previous infections and respond more efficiently the second time they are encountered is the founding principle of vaccines. Now that we understand how blood stem cells bookmark immune response circuits, we should be able to optimize immunization strategies to broaden the protection to infectious agents. It could also more generally lead to new ways to boost the immune response when it underperforms or turn it off when it overreacts, concluded Prof. Michael Sieweke.

The research group of Prof. Michael Sieweke works at the interface of immunology and stem cell research. The scientists focus on the study of hematopoietic stem cells and macrophages, long-lived mature cells of the immune system that fulfil an important role in tissue regeneration. In 2018, Prof. Michael Sieweke received the most valuable research award in Germany: the Alexander von Humboldt Professorship, which brings top international researchers to German universities. In addition to his position as Research Director at the Centre for Immunology at the University of Marseille Luminy, he now acts as Deputy Director at the Center for Regenerative Therapies at TU Dresden (CRTD). CRTD is academic home for scientists from more than 30 nations. Their mission is to discover the principles of cell and tissue regeneration and leveraging this for recognition, treatment and reversal of diseases. The CRTD links the bench to the clinic, scientists to clinicians to pool expertise in stem cells, developmental biology, gene-editing and regeneration towards innovative therapies for neurodegenerative diseases such as Alzheimers and Parkinsons disease, hematological diseases such as leukaemia, metabolic diseases such as diabetes, retina and bone diseases.

Revolutionary Gene-Editing Tool

Cardiovascular or heart disease (CVDs) is the leading cause of death across the world. Heart attacks resulting due to CVDs can cause death, and severe damage to cardiac muscle a muscle that forms the wall of the heart in survivors. However, researchers claim that they have discovered stem-cell activated mechanisms that promote healing after a heart attack.

According to the study by researchers from Mayo Clinic, stem cells were found to reverse the damage and restore cardiac muscle back to its condition before a heart attack. Human cardiopoietic cells obtained from stem cells within the bone marrow were found to hone in on damaged proteins and reverse intricate changes that a heart attack caused.

"The response of the diseased heart to cardiopoietic stem cell treatment revealed development and growth of new blood vessels, along with new heart tissue," said Dr. Kent Arrell, first author of the study, in a statement.

For the study, the researchers examined the diseased hearts of mice. The hearts of mice that received human cardiopoietic stem cell therapy were compared with those of that did not. Nearly 4,000 cardiac proteins were identified using a data science technique to map proteins found in the cardiac muscle. Over 10 per cent of the discovered proteins were found to suffer damage as a result of a heart attack.

"While we anticipated that the stem cell treatment would produce a beneficial outcome, we were surprised how far it shifted the state of diseased hearts away from disease and back toward a healthy, pre-disease state," said Dr. Arrell.

While the organs in the human body have the ability to repair their damaged cells, they may be unable to restore the loss entirely, and this holds good for cardiac cells as well. Dr. Andre Terzic, senior author of the study, said: "The extent of change caused by a heart attack is too great for the heart to repair itself or to prevent further damage from occurring."

He explained that upon the administration of cardiopoietic stem cell therapy to mice, a partial or complete reversal of nearly two-thirds of the damage caused by a heart attack was noted. Around 85 per cent of all cellular functional categories struck by the disease responded favorably to the treatment.

According to the World Health Organisation (WHO), CVDs claim nearly 18 million lives every year, which translates to 31 per cent of all deaths. The findings of the study provide an improved understanding of the restoration of heart health using stem cells and provide a framework for wider utilization of stem cell therapy for the treatment of various conditions.

Stressing that the actual mechanism behind the repair of diseased organs by stem cells is poorly understood, Dr. Terzic added: "This study sheds light on the most intimate, yet comprehensive, regenerative mechanisms paving a road map for responsible and increasingly informed stem cell application."

The novel coronavirus disease 2019 (COVID-19) has grown to become a global public health emergency. Currently, no specific drugs or vaccines are available to cure the patients with COVID-19 infection. Hence, there is a large unmet need for a safe and effective treatment for COVID-19 infected patients, especially the severe cases. A new study offers a promising pathway for developing such a treatment.

The new approach involves intravenous transplantation of mesenchymal stem cells (MSCs) into the patients. It was successfully tested in 7 COVID-19 patients, in Beijing YouAn Hospital, Capital Medical University, China. The results are published in the scientific journal Aging and Disease, entitled "Transplantation of ACE2- Mesenchymal Stem Cells Improves the Outcome of Patients with COVID-19 Pneumonia".

http://www.aginganddisease.org/article/0000/2152-5250/ad-0-0-216.shtml

The study was conducted by a team led by Dr. Robert Chunhua Zhao, with Shanghai University and Chinese Academy of Medical Sciences & Peking Union Medical College, China.

Moreover the study was reviewed by a scientific committee of the International Society on Aging and Disease (ISOAD) and the recently established UNESCO-affiliated committee on Anti-Aging and Disease Prevention http://www.aginganddisease.org/article/2020/2152-5250/ad-11-1-212.shtml

Based on the 14 days observation, MSCs could cure or significantly improve the functional outcomes of all the seven tested patients without observed adverse effects, contrary to 3 controls. The pulmonary function and symptoms of these seven patients were significantly improved after MSC transplantation. Among them, one severe and two common patients recovered and were discharged in 10 days after the treatment. The improvement was particularly dramatic for an elderly (65 y.o.) male patient in severe critical condition. All of his primary and secondary outcomes improved: the inflammation status, the oxygen saturation, and the functional biochemical indicators returned to normal reference values in 2~4 days after the treatment.

The presented evidence suggests that the therapeutic effects are based on the immunomodulatory capacity of mesenchymal stem cells (restoring the balance of the immune system). The coronavirus infection can stimulate a terrible cytokine storm in the lung, disrupting the balance of cytokines (signaling molecules of the immune system) such as IL-2, IL-6, IL-7, GSCF, IP10, MCP1, MIP1A and TNF cytokines, followed by the edema, dysfunction of the air exchange, acute respiratory distress syndrome, acute cardiac injury and the secondary infection, which may lead to death. The bone-marrow derived MSCs could inhibit the over-activation of the immune system and promote endogenous repair by improving the microenvironment, thus they could represent a safe and effective treatment for patients with COVID-19 pneumonia, especially for the patients in critically severe conditions. A larger validation study is required and is already underway, yet the initial results are encouraging.

Notably, the coronavirus-infected pneumonia is more likely to affect older individuals, especially older males, with comorbidities, resulting in their severe and even fatal respiratory diseases such as acute respiratory distress syndrome. In other words, aging appears to be the main risk factor for bad outcomes. However, the cure essentially depends on the patient's own immune system. When the overactivated immune system kills the virus, it produces a large number of inflammatory factors, leading to the severe cytokine storms. This suggests that the main reason for the organs damage may be the virus-induced cytokine storm. Older subjects may be much easier to be affected due to immunosenescence. The study showed remarkable recovery of the elderly patients thanks to restoring their immune function.

Thus, the study may have a broader significance, even beyond the treatment of the severe coronavirus disease. This study exemplifies that the general therapeutic improvement of the immune system in the elderly can improve outcome and survival, which may have more general relevance for other aging-related communicable diseases. Thus, this study may inspire and pave the way for further promising directions to investigate the connection between aging and disease, and to treat both communicable and non-communicable aging-related diseases.

The Romanian journalist Laura tefnu spoke with Dr. Ilia Stambler about the broader implications of this research. Ilia Stambler is a co-author in this study who was involved in the study review, interpretation and discussion. He serves as the Outreach Coordinator of the International Society on Aging and Disease (ISOAD) and Director of Research and Development at Shmuel Harofe Geriatric Medical Center in Israel.

Q: How does it feel to be part of the team which discovered a groundbreaking treatment for what is currently considered one of the biggest global challenges?

A: I feel very honored to be included in this extended international team. I hope this team continues its work that will also involve additional collaborations.

Q: As a researcher, what did you find most interesting about this novel coronavirus? What seems most threatening about this new virus?

A: The spreading ability of this virus is relatively high and it has the capacity to affect the entire global population. This is what makes this virus a particularly strong concern for global public health. The social effects of this epidemic are also of great importance. In a sense, this virus is testing the strength of our public health systems. Will the immunity of our public healthcare be strong enough to contain it? I hope it is.

Q: Did the discovery of this groundbreaking new therapeutic approach make you more optimistic (when it comes to containing and limiting the damage of Covid-19)? In which sense (where was your optimism before the discovery)?

A: I was optimistic before, as I believe that, same as for many infectious diseases in the past, also for this disease, effective therapeutic and preventive measures will be found and used. This work further increased my optimism. Of course, this is an initial study, and this is only one of the potential means in the therapeutic, preventive and hygienic arsenal. More research and confirmation will be needed. Yet, even at this stage, the clear positive result of this study shows that it is indeed possible to improve the outcomes for COVID-19 patients even in severe conditions. Moreover, it gives more hope that effective treatments can be sought and found also for other aging-related infectious diseases and conditions.

Q: Is there an explanation regarding the reasons why Covid-19 seems to pardon children and affects the most elder individuals, especially men?

A: There is yet no clear or fully agreed explanation. But a plausible cause may be due to the so called immuno-senescence phenomenon, or the inability of the aging immune system to cope with new threats and restore the immune balance following the infection. In men the immuno-senescence effects are often more strongly present than in women. Thus, aging appears to be the main risk factor for this disease and if we really wish to defeat this epidemic, we need to address this main risk factor, in other words, we need to therapeutically intervene and ameliorate the degenerative aging process. The proposed mesenchymal stem cell therapy shows the so-called immuno-modulation effects or the ability to generally improve the immune system, help restore the immune balance after disturbances, especially for the elderly. And this can be the more general explanation for its effects against the aging-related COVID-19 pneumonia, as well as potentially other aging-related diseases.

Q: How did you manage to find so fast a treatment that is responding so well?

A: The mesenchymal stem cell treatment has been researched and developed by Dr. Zhao and his team for many years, and indicated positive effects for multiple health conditions. It is exactly because of the common and critical role of the immune system impairment in all these conditions, that the treatment developed by Dr. Zhaos team was already in place and could be immediately used also for this condition dependent on the immune function. Moreover, the success of this therapy against COVID-19 can further boost the research and therapy of other immunity-dependent health conditions and diseases, especially aging-related diseases, due to the common mechanisms of action.

Q: How may this discovery change the game?

A: Unlike other public health measures, like quarantine and hygiene, that can be very quickly applied, the research, development, regulatory approval and application of new therapies is a much slower process. So we should first of all apply the public health measures to contain the epidemic. But the hope is that this therapy will undergo further research and validation as soon as possible, and in case of validated efficacy and safety, will be used in as many patients who need it as possible, as soon as possible. That is exactly why we need to accelerate the research, development and application of promising new therapies. When the new therapy enters wide clinical practice, there are grounds to believe it can improve the health and even save the lives of many patients, not only suffering from COVID-19, but also other conditions.

Q: Which was the response/reaction of authorities after you published the results of your research?

A: The outreach to the authorities in several countries has only started. Moreover, the study is only initial and it is too early to make policy recommendations. A larger validation study is required. Yet, if there is even a slight possibility this could become a life-saving therapy for COVID-19 patients and others, this opportunity should not be missed by the decision makers.

Q: Some treatments are more expensive than others. Will the treatment you discovered be accessible to people, or the cost for producing it will limit its accessibility?

A: The cells for this treatment can be mass produced and can be rather affordable. Of course, the actual price will depend both on the scale of production and pricing policies. And this is already a question that goes beyond pure technology, but becomes a question about the social means to make new therapies available to all. This should also be a crucial part of the public discussion about the social need to promote the rapid research and development as well as broad application of new therapies that are proven to be safe and effective.

Q: Which are the best measures a country can take to limit the spread and the consequences of the novel coronavirus?

The usual quarantine and public hygiene measures are the most feasible and effective: minimization of large gatherings, minimization of travel, cleanliness. We should hope and work for new effective therapies to arrive as soon as possible. But so far public health measures are the most effective and feasible.

In a talk at UAB on March 6, the NIH director shared his thoughts on exceptional opportunities for science and young scientists and highlighted several exciting UAB projects.

NIH Director Francis Collins, M.D., Ph.D., visited UAB on March 6. In addition to his public talk, Collins had breakfast with UAB medical students and met with groups of young researchers and other investigators across campus.Speaking to a packed University of Alabama at Birmingham audience March 6, Francis Collins, M.D., Ph.D., director of the National Institutes of Health, shared his picks of 10 areas of particular excitement and promise in biomedical research.

In nearly every area, UAB scientists are helping to lead the way as Collins himself noted in several cases. At the conclusion of his talk, Collins addedhis advice for young scientists. Here is Collins top 10 list, annotated with some of the UAB work ongoing in each area and ways that faculty, staff and students can get involved.

I am so jazzed with what has become possible with the ability to study single cells and see what they are doing, Collins said. They have been out of our reach now we have reached in. Whether you are studying rheumatoid arthritis, diabetes or the brain, you have the chance to ask each cell what it is doing.

Single-cell sequencing and UAB:Collins noted that Robert Carter, M.D., the acting director of the National Institute of Arthritis and Musculoskeletal and Skin Diseases, was a longtime faculty member at UAB (serving as director of the Division of Clinical Immunology and Rheumatology). For the past several years, UAB researchers have been studying gene expression in subpopulations of immune cells inpatients with rheumatoid arthritis.

Join in:Researchers can take advantage of the single-cell sequencing core facility in UABsComprehensive Flow Cytometry Core, directed by John Mountz, M.D., Ph.D., Goodwin-Blackburn Research Chair in Immunology and professor in the Department of Medicine Division of Clinical Immunology and Rheumatology.

Learn more:Mountz and other heavy users of single-cell sequencing explain how the techniqueslet them travel back in time and morein this UAB Reporter story.

The NIHsBRAIN Initiativeis making this the era where we are going to figure out how the brain works all 86 billion neurons between your ears, Collins said. The linchpin of this advance will be the development of tools to identify new brain cell types and circuits that will improve diagnosis, treatment and prevention of autism, schizophrenia, Parkinsons and other neurological conditions, he said.

Brain tech and UAB:Collins highlighted thework of BRAIN Initiative granteeHarrison Walker, M.D., an associate professor in the Department of Neurology, whose lab has been developing a more sophisticated way to understand the benefits of deep brain stimulation for people with Parkinsons and maybe other conditions, Collins said.

Join in:UABs planned new doctoral program in neuroengineering would be the first of its kind in the country.

Learn more:Find out why neuroengineering is asmart career choicein this UAB Reporter story.

Researchers can now take a blood cell or skin cell and, by adding four magic genes, Collins explained, induce the cells to become stem cells. These induced pluripotent stem (iPS) cells can then in turn be differentiated into any number of different cell types, including nerve cells, heart muscle cells or pancreatic beta cells. The NIH has invested in technology to put iPS-derived cells on specialized tissue chips. Youve got you on a chip, Collins explained. Some of us dream of a day where this might be the best way to figure out whether a drug intervention is going to work for you or youre going to be one of those people that has a bad consequence.

iPS cells at UAB:Collins displayed images of thecutting-edge cardiac tissue chipdeveloped by a UAB team led by Palaniappan Sethu, Ph.D., an associate professor in the Department of Biomedical Engineering and the Division of Cardiovascular Disease. The work allows the development of cardiomyocytes that can be used to study heart failure and other conditions, Collins said.

We have kind of ignored the fact that we have all these microbes living on us and in us until fairly recently, Collins said. But now it is clear that we are not an organism we are a superorganism formed with the trillions of microbes present in and on our bodies, he said. This microbiome plays a significant role not just in skin and intestinal diseases but much more broadly.

Microbiome at UAB:Collins explained that work led by Casey Morrow, Ph.D., and Casey Weaver, M.D., co-directors of theMicrobiome/Gnotobiotics Shared Facility, has revealed intriguing information abouthow antibiotics affect the gut microbiome. Their approach has potential implications for understanding, preserving and improving health, Collins said.

Join in:Several ongoing clinical trials at UAB are studying the microbiome, including a studymodifying diet to improve gut microbiotaand an investigation of the microbiomes ofpostmenopausal women looking for outcomes and response to estrogen therapy.

Learn more:This UAB News storyexplains the UAB researchthat Collins highlighted.

Another deadly influenza outbreak is likely in the future, Collins said. What we need is not an influenza vaccine that you have to redesign every year, but something that would actually block influenza viruses, he said. Is that even possible? It just might be.

Influenza research at UAB:Were probably at least a decade away from a universal influenza vaccine. But work ongoing at UAB in the NIH-fundedAntiviral Drug Discovery and Development Center(AD3C), led by Distinguished Professor Richard Whitley, M.D., is focused on such an influenza breakthrough.

Join in:For now, the most important thing you can do to stop the flu is to get a flu vaccination. Employees can schedule afree flu vaccination here.

Learn more:Why get the flu shot? What is it like? How can you disinfect your home after the flu? Get all the information atthis comprehensive sitefrom UAB News.

The NIH has a role to play in tackling the crisis of opioid addiction and deaths, Collins said. The NIHs Helping to End Addiction Long-term (HEAL) initiative is an all-hands-on-deck effort, he said, involving almost every NIH institute and center, with the goal of uncovering new targets for preventing addiction and improving pain treatment by developing non-addictive pain medicines.

Addiction prevention at UAB:A big part of this initiative involves education to help professionals and the public understand what to do, Collins said. The NIH Centers of Excellence in Pain Education (CoEPE), including one at UAB, are hubs for the development, evaluation and distribution of pain-management curriculum resources to enhance pain education for health care professionals.

We are all pretty darn jazzed about whats happened in the past few years in terms of developing a new modality for treating cancer we had surgery, we had radiation, we had chemotherapy, but now weve got immunotherapy, Collins said.

Educating immune system cells to go after cancer in therapies such as CAR-T cell therapy is the hottest science in cancer, he said. I would argue this is a really exciting moment where the oncologists and the immunologists together are doing amazing things.

Immunotherapy at UAB:I had to say something about immunology since Im at UAB given that Max Cooper, whojust got the Lasker Awardfor [his] B and T cell discoveries, was here, Collins said. This is a place I would hope where lots of interesting ideas are going to continue to emerge.

Assistant Professor Ben Larimer, Ph.D., is pursuing a new kind of PET imaging test that could give clinicians afast, accurate picture of whether immunotherapy is workingfor a patient in this UAB Reporter article.

The All of Us Research Program from NIH aims to enroll a million Americans to move away from the one-size-fits-all approach to medicine and really understand individual differences, Collins said. The program, which launched in 2018 and is already one-third of the way to its enrollment goal, has a prevention rather than a disease treatment approach; it is collecting information on environmental exposures, health practices, diet, exercise and more, in addition to genetics, from those participants.

All of Us at UAB:UAB has been doing a fantastic job of enrolling participants, Collins noted. In fact, the Southern Network of the All of Us Research Program, led by UAB, has consistently been at the top in terms of nationwide enrollment, as School of Medicine Dean Selwyn Vickers, M.D., noted in introducing Collins.

Join in:Sign up forAll of Usat UAB today.

Learn more:UABs success in enrolling participants has led to anew pilot study aimed at increasing participant retention rates.

Rare Disease Day, on Feb. 29, brought together hundreds of rare disease research advocates at the NIH, Collins said. NIH needs to play a special role because many diseases are so rare that pharmaceutical companies will not focus on them, he said. We need to find answers that are scalable, so you dont have to come up with a strategy for all 6,500 rare diseases.

Rare diseases at UAB: The Undiagnosed Diseases Network, which includes aUAB siteled by Chief Genomics Officer Bruce Korf, M.D., Ph.D., is a national network that brings together experts in a wide range of conditions to help patients, Collins said.

Participants in theAlabama Genomic Health Initiative, also led by Korf, donate a small blood sample that is tested for the presence of specific genetic variants. Individuals with indications of genetic disease receive whole-genome sequencing. Collins noted that lessons from the AGHI helped guide development of the All of Us Research Program.

Collins also credited UABs Tim Townes, Ph.D., professor emeritus in the Department of Biochemistry and Molecular Genetics, for developing the most significantly accurate model of sickle cell disease in a mouse which has been a great service to the [research] community. UAB is now participating in anexciting clinical trial of a gene-editing technique to treat sickle cellalong with other new targeted therapies for the devastating blood disease.

Join in:In addition to UABs Undiagnosed Diseases Program (which requires a physician referral) and the AGHI, patients and providers can contact theUAB Precision Medicine Institute, led by Director Matt Might, Ph.D. The institute develops precisely targeted treatments based on a patients unique genetic makeup.

We know that science, like everything else, is more productive when teams are diverse than if they are all looking the same, Collins said. My number one priority as NIH director is to be sure we are doing everything we can to nurture and encourage the best and brightest to join this effort.

Research diversity at UAB:TheNeuroscience Roadmap Scholars Programat UAB, supported by an NIH R25 grant, is designed to enhance engagement and retention of under-represented graduate trainees in the neuroscience workforce. This is one of several UAB initiatives to increased under-represented groups and celebrate diversity. These include several programs from theMinority Health and Health Disparities Research Centerthat support minority students from the undergraduate level to postdocs; thePartnership Research Summer Training Program, which provides undergraduates and especially minority students with the opportunity to work in UAB cancer research labs; theDeans Excellence Award in Diversityin the School of Medicine; and the newly announcedUnderrepresented in Medicine Senior Scholarship Programfor fourth-year medical students.

In answer to a students question, Collins also shared his advice to young scientists. One suggestion: Every investigator needs to be pretty comfortable with some of the computational approaches to science, Collins said. Big data is here artificial intelligence, machine-learning. We can all get into that space. But its going to take some training, and it will be really helpful to have those skills.

Looking to the future with Dr. Francis Collins - UAB News

Skin Stem Cells Comments Off on Looking to the future with Dr. Francis Collins – UAB News | March 13th, 2020

Boston Children's Hospital researchers used an investigational gene therapy to treat heart failure in a mouse model of Barth syndrome. Barth syndrome is a rare genetic disorder in boys that results in life-threatening heart failure. It also causes weakness of the skeletal muscles and the immune system. The disease is caused by a mutation of a gene known as tafazzin or TAZ.

In 2014, William Pu and researchers at Boston Childrens Hospital collaborated with the Wyss Institute to develop a beating heart on a chip model of Barth syndrome. It used heart-muscle cells with the TAZ mutation that came from patients own skin cells. This was able to prove that TAZ was the cause of the cardiac problems. The heart muscle cells did not organize normally and the mitochondria, the cells energy engines, were disorganized, resulting in the heart muscle contracting weakly. By adding healthy TAZ genes, the cells behaved more normally.

The next step was an animal model. The results of the research were published in the journal Circulation Research.

The animal model was a hurdle in the field for a long time, Pu said. Pu is director of Basic and Translational Cardiovascular Research at Boston Childrens and a member of the Harvard Stem Cell Institute. Efforts to make a mouse model using traditional methods had been unsuccessful.

Douglas Strathdees research team at the Beatson Institute for Cancer Research in the UK recently developed animal models of Barth syndrome. Pu, research fellow Suya Wang, and colleagues characterized the knockout mice into two types. One had the TAZ gene deleted throughout the body; the other had the TAZ gene deleted just in the heart.

Most of the mice that had TAZ deleted throughout their whole bodies died before birth, likely from skeletal muscle weakness. Of those that survived, they developed progressive cardiomyopathy, where the heart muscle enlarges and is less able to pump blood. The heart also showed signs of scarring similar to humans with dilated cardiomyopathy, where the hearts left ventricle is dilated and thin-walled.

The mice that lacked TAZ only in their heart tissue that survived to birth had the same features. Electron microscopy indicated that the heart muscle cells and mitochondria were poorly organized.

Pu and Wang and their team then used gene therapy to replace TAZ in the newborn mice and in older mice, using slightly different techniques. In the newborn mice the engineered virus was injected under the skin; in the older mice it was injected intravenously. The mice who had no TAZ in their bodies and received the gene therapy survived to adulthood.

In the newborn mice receiving the gene therapy, the therapy prevented cardiac dysfunction and scarring. In the older mice receiving the therapy, it reversed the cardiac dysfunction.

The study also showed that TAZ gene therapy offered durable treatment of the cardiomyocytes and skeletal muscle cells, but only when at least 70% of the heart muscle cells had taken up the gene via the therapy. Which the researchers point out that when the therapy is developed for humans, that will be the most challenging problem. You cant just scale up the dose because of inflammatory immune responses, and multiple doses wont work either because the body develops an immune response. Maintaining the gene-corrected cell is also a problem. In the heart muscles of the treated mice, the corrected TAZ gene stayed relatively stable, but slowly dropped in skeletal muscles.

The biggest takeaway was that the gene therapy was highly effective, Pu said. We have some things to think about to maximize the percentage of muscle cell transduction, and to make sure the gene therapy is durable, particularly in skeletal muscle.

Gene Therapy Reverses Heart Failure in Animal Model of Barth Syndrome - BioSpace

Skin Stem Cells Comments Off on Gene Therapy Reverses Heart Failure in Animal Model of Barth Syndrome – BioSpace | March 13th, 2020

Barth syndromeis a rare metabolic disease caused by mutation of a gene calledtafazzinorTAZ. It can cause life-threatening heart failure and also weakens the skeletal muscles, undercuts the immune response, and impairs overall growth. Because Barth syndrome is X-linked, it almost always occurs in boys. There is no cure or specific treatment.

In 2014, to get a better understanding of the disease,William Pu, MD, and colleagues at Boston Childrens Hospital collaborated with the Wyss Institute to create a beatingheart on a chip model of Barth syndrome. The model used heart-muscle cells with theTAZmutation, derived from patients own skin cells.It showedthatTAZis truly at the heart of cardiac dysfunction: the heart muscle cells did not assemble normally, mitochondria inside the cells were disorganized, and heart tissue contracted weakly. Adding a healthyTAZgene normalized these features, suggesting that gene replacement therapy could be a viable treatment.

But to fully capture Barth syndrome and its whole-body effects, Pu and colleagues needed an animal model. The animal model was a hurdle in the field for a long time, says Pu, director of Basic and Translational Cardiovascular Research at Boston Childrens and a member of the Harvard Stem Cell Institute. Efforts to make a mouse model using traditional methods had been unsuccessful.

As described in the journalCirculation Research, most mice with the whole-bodyTAZdeletion died before birth, apparently because of skeletal muscle weakness. But some survived, and these mice developed progressive cardiomyopathy, in which the heart muscle enlarges and loses pumping capacity. Their hearts also showed scarring, and, similar to human patients with dilatedcardiomyopathy, the hearts left ventricle was dilated and thin-walled.

Mice lackingTAZjust in their cardiac tissue, which all survived to birth, showed the same features. Electron microscopy showed heart muscle tissue to be poorly organized, as were the mitochondria within the cells.

Pu, Wang, and colleagues then used gene therapy to replaceTAZ, injecting an engineered virus under the skin (in newborn mice) or intravenously (in older mice). Treated mice with whole-bodyTAZdeletions were able to survive to adulthood.TAZgene therapy also prevented cardiac dysfunction and scarring when given to newborn mice, and reversed established cardiac dysfunction in older mice whether the mice had whole-body or heart-onlyTAZdeletions.

Thats where the challenge will lie in translating the results to humans. Simply scaling up the dose of gene therapy wont work: In large animals like us, large doses risk a dangerous inflammatory immune response. Giving multiple doses of gene therapy wont work either.

The problem is that neutralizing antibodies to the virus develop after the first dose, says Pu. Getting enough of the muscle cells corrected in humans may be a challenge.

Another challenge is maintaining populations of gene-corrected cells. While levels of the correctedTAZgene remained fairly stable in the hearts of the treated mice, they gradually declined in skeletal muscles.

The biggest takeaway was that the gene therapy was highly effective, says Pu. We have some things to think about to maximize the percentage of muscle cell transduction, and to make sure the gene therapy is durable, particularly in skeletal muscle."

A 40-year-old HIV patient has been declared cured after a promising treatment has left him with no active virus. The man, Adam Castillejo, was the subject of extensive research in early 2019 after doctors failed to find HIV in his body over an 18-month period after previously being diagnosed in 2003.

Castillejo, known by the nickname London Patient lived with the disease for many years, taking medicine to manage it since 2012. That same year he was diagnosed with Hodgkins Lymphoma and later endured a bone marrow transplant. That operation may have ultimately cured him of HIV and appears to have made him only the second person to ever be cured of the disease that causes AIDS.

As ScienceAlert reports, the bone marrow transplant that doctors performed on Castillejo used cells from a donor with a very special genetic quirk. The cells are thought to work against HIV in the body, but there was no guarantee that the transplant would provide any concrete benefits beyond treating the cancer.

However, it appears as though the decision to treat Castillejo with the unique stem cells worked in more ways than one and last year doctors announced they couldnt find the virus in his body after 18 months. At the time, they were hesitant to declare the London Patient cured, but after a new round of testing returned the same results, they are more confident that the active form of the virus has indeed been defeated.

This is a unique position to be in, a unique and very humbling position, Castillejo told the New York Times. I want to be an ambassador of hope.

While this sounds like incredible news and for Castillejo, it certainly is the treatment is not an option for everyone. With cancer limiting their options, doctors used the stem cell transplant as a last resort to keep him alive. Its a serious operation and one that was only performed because Castillejos condition was so dire.

Castillejo and the other HIV patient who had similar results, known as the Berlin Patient, may be uniquely fortunate. The doctors note that there are others who have had the same transplant performed but did not improve as rapidly as the others. There are obviously many factors at work here and as exciting as it is to see a second person cured of this terrible disease, theres a lot more work to be done before we can say HIV has been truly beaten.

HIV patient appears to be cured after stem cell treatment - New York Post

Bone Marrow Stem Cells Comments Off on HIV patient appears to be cured after stem cell treatment – New York Post | March 13th, 2020

Although most of the news from the world of health and medicine has been quite bleak lately, there are still major strides being made in the sector in an effort to combat the worst illnesses that plague humankind. One such stride was just announced, and its certainly worth celebrating: A second person has been cured of HIV.

In a study published in the medical journal, The Lancet, which comes via Medical News Daily, researchers in London say theyve been able to cure a patient of HIV; meaning the patient tested negative for HIV for an extended period of time (30 months as of March, 2020) despite the lack of antiretroviral therapy.

The person whos been cured, Adam Castillejo, was formerly known only as the London patient in order to protect his identity. But Castillejo, who lives in London, came forward recently, and said that he aims to be an ambassador of hope.

The first person to be cured of HIV, Timothy Ray Brown, an American known originally as the Berlin patient, revealed his identity in 2010, saying that I wanted to do what I could to make [a cure] possible. My first step was releasing my name and image to the public. Brown lived and was treated in Berlin. Incidentally, he is technically the second Berlin patient because the results from treatment of the first one are debatable.

AIDS Policy Project with Timothy Ray Brown (third from left with sunglasses). Griffin Boyce.

Castillejo, as well as Brown, were cured of HIV not by antiretroviral medications, which are often able to drastically mitigate the effects, and transmission rate of, HIV, but rather by stem cell transplants from donor bone marrow. Both Castillejo and Brown hadand may still have, that is unclearcancer along with HIV, and were treated with the stem cell transplants primarily to tackle the former disease. (It seems in Castillejos case doctors and researchers were hoping to cure both simultaneously.)

Both Brown and Castillejo underwent a procedure known as a Hematopoietic stem cell transplantation (or HSCT), which involves injecting bone marrow stem cells from a donor, whos often times a parent or sibling, into the recipients bloodstream. Castillejos HSCT treatment was different from Browns, as well as many others, because it was performed with cells that expressed the CCR5 gene.

A video from the MD Anderson Cancer Center that gives a brief outline of how bone marrow stem cell transplants work.

In Castillejos case, stem cells with genomes that express the CCR5 gene were selected because of the fact that it allows for the production of the CCR5 protein: a protein that makes people far more resistant to HIV-1, which accounts for the vast majority of global HIV infections.

While Castillejo received stem cells that did express the CCR5 gene, Brown did notat least according to the study in The Lancet. In fact, according to a 2017 article in New Scientist (which says that Brown received cells with a mutated CCR5 gene, rather than an unexpressed CCR5 gene), some experts believe the curing of Browns HIV was actually due to a potential side effect of his procedure, known as graft-versus-host disease. According to New Scientist, these experts believe that the donor cells attacked Browns native, HIV-infected immune cells, subsequently killing off the virus.

In Castillejos case, on the other hand, it seems there was no graft-versus-host issue that could account for his diminishment of HIV infection levels beyond whats expected to be detectable. Instead, the authors of the study say that one of the implications here is that the Long-term remission of HIV-1 can be achieved utilizing these kinds of cells. The authors also say this method does not require total body irradiation, which would usually be required in cases like these to weaken a recipients immune system in order to allow them to accept donor cells.

Unfortunately, it seems the treatment that cured Castillejo of HIV is a nonstarter when it comes to mass deployment. There are fatal side effects associated with HSCT, with host-versus-graft chief among them, and doctors say that it should only be performed when there are no other options left.

Prof. Ravindra Kumar Gupta from the University of Cambridge in the U.K., the lead author of the study, told Medical News Daily that [Its] important to note that this curative treatment is high risk and only used as a last resort for patients with HIV who also have life threatening hematological [blood] malignancies.

But Gupta and the other authors of the study still appear to be optimistic that this stands as a proof-of-concept for the idea of using CCR5 gene editing to cure HIV on a larger scale. They warn in their study, however, that several barriers, including the need for increased gene editing efficiency and a lack of robust safety data, still stand in the way of something that could be used as a scalable strategy for tackling HIV.

What do you think about this method of treating HIV? Do you think gene editing will play a big role in curing HIV, or do you think there are other, more promising treatments worth pursuing instead? Let us know your thoughts in the comments.

A Second Person Has Been Cured of HIV - Nerdist

Bone Marrow Stem Cells Comments Off on A Second Person Has Been Cured of HIV – Nerdist | March 13th, 2020

Newswise The number of COVID-19 cases are expected to continue to grow across the globe in the upcoming months and that means more people will have to take extra measures to help protect themselves and reduce the transmission of the disease. This is particularly important for people with cancer, whose immune systems have often been weakened by their cancer treatments.

But does that mean people with cancer should stockpile hand sanitizer and face masks?

Oncologists Gary Schiller, MD, and Joshua Sasine, MD, PhD, help explain what cancer patients need to know about COVID-19.

Dr. Schiller is a professor of hematology/oncology at the David Geffen School of Medicine at UCLA and director of the hematological malignancies/stem cell transplantation unit, and Dr. Sasine is an assistant professor of medicine and director of the CAR T cell program at the UCLA Jonsson Comprehensive Cancer Center.

Which cancer patients should be concerned about coronavirus?

Sasine: The patients most at risk are those with bone marrow cancers or who have had a bone marrow transplant within the last 12 months. If patients have cancer and are on active chemotherapy, they are also at a higher risk than the general population. This is especially true if they are over the age of 60.

Schiller: Bone marrow transplant recipients who received bone marrow from other people are the most immunocompromised patients we take care of and the group at greatest risk for sustaining a life-threatening complication from an infection.

What does it mean to have a compromised immune system?

Sasine: The body's white blood cells normally clear out infections, like bacteria, viruses, and fungi. When the cells have either decreased in number, function, or both, the immune system is compromised. This can be due to having cancer, HIV, getting chemotherapy, and many other situations. This means that a person is more likely than others to contract an infection and the infection is likely to do more harm than average. It might also last longer.

Are there precautions cancer patients should be taking?

Schiller: Patients who are immunocompromised need to be wary of going into crowds, should maintain good hand washing techniques and should stay away from individuals who have a cough.

Sasine: For most events, canceling plans is ideal. However, sometimes one must weigh the risks and benefits. If there is a very important event (son or daughter is getting married, etc.) this might be a risk worth taking.

Should cancer patients delay travel plans?

Schiller: For patients with malignancies of the blood and bone marrow, and patients who had bone marrow transplants, I absolutely tell them to delay travel. Dont travel right now.

Is it safe for patients to come to the hospital and clinics for treatment?

Schiller: Yes. Weve been working to develop better isolation procedures and policies to isolate the potentially sick patients from our immunocompromised patients. For example, bringing the potentially sick patients in through a different entrance to isolate them in the waiting room and put them in an isolation room for evaluation.

Should patients be wearing a mask or stockpile hand sanitizer?

Schiller: A mask is not sufficient protection and were concerned that if you wear a mask, especially one that is insufficiently protective, then you have a false sense of security and you may put yourself in a position that might compromise your safety. In regards to hand sanitizer, I would like my patients to stockpile on soap and water. That would be more effective than using hand sanitizer repeatedly.

Cancer and COVID-19: What you should know - Newswise

Bone Marrow Stem Cells Comments Off on Cancer and COVID-19: What you should know – Newswise | March 13th, 2020

NEW YORK, March 10, 2020 (GLOBE NEWSWIRE) -- Mesoblast Limited(Nasdaq: MESO; ASX:MSB) today announced that it plans to evaluate its allogeneic mesenchymal stem cell (MSC) product candidate remestemcel-L in patients with acute respiratory distress syndrome (ARDS) caused by coronavirus (COVID-19) in the United States, Australia, China and Europe. The Company is in active discussions with various government and regulatory authorities, medical institutions and pharmaceutical companies to implement these activities.

Mortality in COVID-19 infected patients with the inflammatory lung condition acute respiratory distress syndrome (ARDS) is reported to approach 50%, and is associated with older age, co-morbidities such as diabetes, higher disease severity, and elevated markers of inflammation.1 Current therapeutic interventions do not appear to be improving in-hospital survival.1

Remestemcel-L has potential for use in the treatment of ARDS, which is the principal cause of death in COVID-19 infection.1 This is supported by recently published results from an investigator-initiated clinical study conducted in China which reported that allogeneic MSCs cured or significantly improved functional outcomes in all seven treated patients with severe COVID-19 pneumonia.2

Additionally, in post-hoc analyses of a 60-patient randomized controlled study in chronic obstructive pulmonary disease (COPD), remestemcel-L infusions were well tolerated, significantly reduced inflammatory biomarkers, and significantly improved pulmonary function in those patients with elevated inflammatory biomarkers. Since the same inflammatory biomarkers are also elevated in COVID-19, these data suggest that remestemcel-L could be useful in the treatment of patients with ARDS due to COVID-19.The COPD study results have been submitted for presentation at an international conference, with full results to be submitted for publication shortly.

Remestemcel-L is being studied in numerous clinical trials across several inflammatory conditions, including in elderly patients with lung disease and adults and children with steroid-refractory acute graft versus host disease (aGVHD).3-5 This product candidate is currently being reviewed by the United States Food and Drug Administration (FDA) for potential approval in the treatment of children with steroid-refractory aGVHD.

Remestemcel-L Remestemcel-L is being developed for rare pediatric and adult inflammatory conditions. It is an investigational therapy comprising culture-expanded MSCs derived from the bone marrow of an unrelated donor and is administered in a series of intravenous infusions. Remestemcel-L is believed to have immunomodulatory properties to counteract the inflammatory processes that are implicated in several diseases by down-regulating the production of pro-inflammatory cytokines, increasing production of anti-inflammatory cytokines, and enabling recruitment of naturally occurring anti-inflammatory cells to involved tissues.

Intellectual PropertyMesoblasts intellectual property (IP) portfolio encompasses over 1,000 patents or patent applications in all major markets and includes the use of MSCs obtained from any source for patients with acute respiratory distress syndrome (ARDS),and for inflammatory lung disease due to coronavirus (COVID-19), influenza and other viruses. Additionally, these patents cover Mesoblasts manufacturing processes that yield industrial-scale cellular medicines.This IP position is expected to provide Mesoblast with substantial commercial advantages as it develops its product candidates for these conditions.

Mesoblast To Evaluate Anti-Inflammatory Cell Therapy Remestemcel-L For Treatment Of COVID-19 Lung Disease - BioSpace

Bone Marrow Stem Cells Comments Off on Mesoblast To Evaluate Anti-Inflammatory Cell Therapy Remestemcel-L For Treatment Of COVID-19 Lung Disease – BioSpace | March 13th, 2020

Genes may determine what characteristics are passed down from parent to offspring, but each cell expresses these genes differently based on external epigenetic modifications. Epigenetics dont alter the gene sequence (genotype), but they do influence cell behavior and function (phenotype). The study of epigenetics helps us understand how phenotypic changes lead to disease, stem cell differentiation, and essentially, what drives the fate of every cell in the human body.The epigenome is not consistent between cells, or even between cells of the same type. Individual modifications come and go throughout a cells lifetime. Therefore, scientists are faced with the steep challenge as they try to decipher the role of epigenetics in disease and development.[i] Understanding intercellular heterogeneity is key here. The epigenome must be examined at single-cell resolution.

Now, with the advancement of single-cell sequencing methods like the single-cell assay for transposase accessible chromatin (scATAC-seq), researchers have access to sophisticated techniques to map large cell populations, one cell at a time. The resulting epigenomic information provides unprecedented insight into the different cell types that come together to form organs and organ systems, as well as pathogenic modifications associated with disease.

Every single cell has unique epigenomic instructions that guide how it expresses its genes and these instructions are subject to change. A map locating epigenetic modifications in the genome would help scientists understand how epigenetics drives cellular differentiation. But until recently, epigenetic assays mainly focused on select regions of DNA or gave bulk results across an entire sample of cells.[ii] These assays were not designed to detect epigenetic patterns in individual cells.

Single-cell tools like scATAC-seq help us get a grasp on intracellular heterogeneity, differentiate between cell populations and map the role of epigenetics in the larger context of an organism. By building a collection of scATAC-seq data, scientists have begun generating a cell atlas to provide insight into the role of epigenetics during the intricate biological processes that occur throughout the human lifetime.

During ATAC-seq, a hyperactive transposase mutant, Tn5, binds to open chromatin (euchromatin) regions. Wherever Tn5 binds, it cleaves the DNA and attaches sequencing adapters. Then, after PCR amplification, ATAC fragments are sequenced to identify open chromatin regions. ATAC results indicate where nucleosomes are typically positioned in the cell sample and which regions of the genome are open for transcription factors to bind. As such, scientists use ATAC-Seq as a first-pass screening approach to identify changes in chromatin accessibility between samples.

ATAC-seq has many practical applications, but it cant account for the cell-to-cell variability thats often an important aspect of developmental processes and disease. So, researchers developed a new assay in which microfluidic technology is used to isolate individual cells before ATAC-seq.[iv] This assay provides epigenomic information at single cell resolution, earning it the name scATAC-seq.

The key to the scATAC-seq method is that it isolates genomes of individual cells early on to perform a separate ATAC-seq reaction on each individual cell. Then, open regions of the genome are cleaved by the Tn5 transposase, tagged with sequencing adapters and amplified with barcoded cell-identifying primers. Subsequently, the barcoded libraries of ATAC fragments, (each representing an individual cell) are pooled together and sequenced to reveal open chromatin regions of thousands of individual cells.

The first droplet-based iteration of the scATAC-seq method (dscATAC-seq) uses a single cell isolator to encapsulate thousands of individual nuclei in nanoliter-sized droplets for ATAC sequencing. It uses a custom Tn5 transposase to enhance library complexity and signal resolution. Compared to the original microfluidic method, the new workflow is faster and yields greater biological insight with less time and effort spent on sequencing. To demonstrate its power and potential, this technique has been used to conduct an unbiased analysis of the many different cell types and regulatory elements in a mouse brain. [v]

To capture single cell data on a truly massive scale, combinatorial indexing was next introduced into the dscATAC-seq workflow. This new method, called dsciATAC-seq, enables researchers to assess up to 50,000 cells in a single assay. Assaying a large volume of cells is possible because, in dsciATAC-seq, the hyperactive mutant transposase integrates a first set of barcodes as it cleaves open regions of chromatin in each nucleus. Because every cells DNA already carries a barcode, multiple cells can be loaded into a single droplet. Then, as usual, ATAC fragments are amplified with a second set of barcoded primers. After sequencing these fragments, the two sets of barcodes are used to derive epigenomic profiles for tens of thousands of cells.

Putting the dsciATAC-seq method to the test, researchers have studied immune cell clusters from human bone marrow derived cells to illustrate how the chromatin accessibility landscape in these cells changes according to different stimulants at the single cell level.5Although the number of cells that a single scATAC-seq experiment can evaluate has grown dramatically, it will take a continued concerted effort from scientists across many disciplines to create a comprehensive map of the human epigenome, encompassing data from trillions of cells.[vi] Furthermore, to help decode the patterns we find in the human epigenome, it may be valuable to gather information about the epigenomes of animals commonly used as research models. As each of these maps become increasingly detailed, scientists will gain a more thorough understanding of how biological process work and may apply this knowledge towards developing better treatments for complex diseases.

Global Stem Cell Therapy Market: Overview

Also called regenerative medicine, stem cell therapy encourages the reparative response of damaged, diseased, or dysfunctional tissue via the use of stem cells and their derivatives. Replacing the practice of organ transplantations, stem cell therapies have eliminated the dependence on availability of donors. Bone marrow transplant is perhaps the most commonly employed stem cell therapy.

Osteoarthritis, cerebral palsy, heart failure, multiple sclerosis and even hearing loss could be treated using stem cell therapies. Doctors have successfully performed stem cell transplants that significantly aid patients fight cancers such as leukemia and other blood-related diseases.

Global Stem Cell Therapy Market: Key Trends

The key factors influencing the growth of the global stem cell therapy market are increasing funds in the development of new stem lines, the advent of advanced genomic procedures used in stem cell analysis, and greater emphasis on human embryonic stem cells. As the traditional organ transplantations are associated with limitations such as infection, rejection, and immunosuppression along with high reliance on organ donors, the demand for stem cell therapy is likely to soar. The growing deployment of stem cells in the treatment of wounds and damaged skin, scarring, and grafts is another prominent catalyst of the market.

On the contrary, inadequate infrastructural facilities coupled with ethical issues related to embryonic stem cells might impede the growth of the market. However, the ongoing research for the manipulation of stem cells from cord blood cells, bone marrow, and skin for the treatment of ailments including cardiovascular and diabetes will open up new doors for the advancement of the market.

Global Stem Cell Therapy Market: Market Potential

A number of new studies, research projects, and development of novel therapies have come forth in the global market for stem cell therapy. Several of these treatments are in the pipeline, while many others have received approvals by regulatory bodies.

Subsequently, it has been approved by the U.S. FDA. If this therapy is well- received by the market, nearly 1.9 million AMI patients could be treated through this stem cell therapy.

Another significant development is the granting of a patent to Israel-based Kadimastem Ltd. for its novel stem-cell based technology to be used in the treatment of multiple sclerosis (MS) and other similar conditions of the nervous system. The companys technology used for producing supporting cells in the central nervous system, taken from human stem cells such as myelin-producing cells is also covered in the patent.

Stem Cell Therapy Market Report on Recent Adoption 2025 - 3rd Watch News

Bone Marrow Stem Cells Comments Off on Stem Cell Therapy Market Report on Recent Adoption 2025 – 3rd Watch News | March 13th, 2020

A second patient has been cured of HIV after undergoing stem cell transplant treatment, doctors said Tuesday, after finding no trace of infection 30 months after he stopped traditional treatment.

The so-called "London Patient", a cancer sufferer originally from Venezuela, made headlines last year when researchers at the University of Cambridge reported they had found no trace of the AIDS-causing virus in his blood for 18 months.

Ravindra Gupta, lead author of the study published in The Lancet HIV, said the new test results were "even more remarkable" and likely demonstrated the patient was cured.

"We've tested a sizeable set of sites that HIV likes to hide in and they are all pretty much negative for an active virus," Gupta told AFP.

The patient, who revealed his identity this week as Adam Castillejo, 40, was diagnosed with HIV in 2003 and had been on medication to keep the disease in check since 2012.

Later that year, he was diagnosed with advanced Hodgkin's Lymphoma, a deadly cancer.

In 2016 he underwent a bone marrow transplant to treat blood cancer, receiving stem cells from donors with a genetic mutation present in less than one percent of Europeans that prevents HIV from taking hold.

He becomes only the second person to be cured of HIV after American Timothy Brown, known as the "Berlin Patient", recovered from HIV in 2011 following similar treatment.

Viral tests of Castillejo's cerebral fluid, intestinal tissue and lymphoid tissue more than two years after stopping antiretroviral treatment showed no active infection.

Gupta said the tests uncovered HIV "fossils" - fragments of the virus that were now incapable of reproducing, and were therefore safe.

"We'd expect that," he said.

"It's quite hard to imagine that all trace of a virus that infects billions of cells was eliminated from the body."

Researchers cautioned that the breakthrough did not constitute a generalised cure for HIV, which leads to nearly one million deaths every year.

Castillejo's treatment was a "last resort" as his blood cancer would likely have killed him without intervention, according to Gupta.

The Cambridge doctor said that there were "several other" patients who had undergone similar treatment but who were less far along in their remission.

"There will probably be more but they will take time," he said.

Researchers are currently weighing up whether or not patients suffering from drug-resistant forms of HIV might be eligible for stem cell transplants in future, something Gupta said would require careful ethical consideration.

"You'd have to weigh up the fact that there's a 10-percent mortality rate from doing a stem-cell transplant against what the risk of death would be if we did nothing," he said.

Castillejo himself said that the experience had prompted him to come forward and identify himself in order to help spread awareness of HIV.

This is a unique position to be in, a unique and very humbling position," he told The New York Times.

Sharon Lewin, an infectious disease expert at the University of Melbourne and member of the International AIDS Society, said Castillejo's case was "exciting".

"But we need to also place it in context - curing people of HIV via a bone marrow transplant is just not a viable option on any kind of scale," she said.

"We need to constantly reiterate the importance of, prevention, early testing and treatment adherence as the pillars of the current global response to HIV/AIDS."
