Since losing her cousin to leukemia during childhood, Heather Lynn made it her mission to ensure others battling blood cancers get a second chance at life. Earlier this year, the St. Louis native fulfilled that life purpose: saving a stranger by donating her stem cells.

Five years ago, Lynn became the director of global special events for DKMS, the worlds largest bone marrow and blood stem cell donor center, and registered as a potential donor with the hope that someday she could give a blood cancer patient what her cousin didnt have a second chance at life and more time with the patients family.

Amid this years coronaviral pandemic, Lynn received the life-changing call from a colleague that she was a match for a 58-year-old man battling acute myeloid leukemia. I screamed with joy, Lynn recalls. I was a match for someone with blood cancer and was about to be the first employee at DKMS to donate and ultimately save someones life. After the call, Lynn realized she would be giving more than stem cells: I was giving something much bigger: hope.

Despite the uncertainty surrounding COVID-19, Lynn felt a strong sense of purpose to help this man and donated her stem cells to save his life. I have seen how much someones life can change with a blood cancer diagnosis, Lynn says. The fear, the pain, the loss it can be devastating. I have spent the past five years working to elevate the message about donating and how easy it is to sign up and give back it simply requires swabbing the inside of each cheek for 60 seconds.

Community Cord Blood Banking, a stem cell banking initiative introduced by LifeCell in 2017, has helped save the life of a seven-year-old girl from Nashik in Maharashtra who was suffering from aplastic anaemia, a rare and serious blood disorder.

In a major breakthrough, a team of senior doctors from LOTUS Institute of Haematology, Oncology and Bone Marrow Transplantation, recently conducted Indias first dual cord blood transplant through an unrelated donor using Community Stem Cell Banking. People familiar with the development said the transplant was challenging because no apt bone marrow donors were available and the cost of retrieval of matching units from public cord blood banks would have been high.

The girls parents, as members of LifeCell Community Bank, placed a request for two matching cord blood units after the childs sibling was found to be only a 50% (4/8) match. Two high-quality matches (7/8) were found in the registry, which fulfilled the requirement for umbilical cord blood transplantation. The parents could withdraw the matched units at no extra expense, which would have cost around 45 lakh per unit.

Mayur Abhaya, MD, LifeCell International said, The purpose of Community Cord Blood Banking is to ensure easy and rapid access to stem cells for every Indian without the hurdles of public and private banking models. While stem cells from the umbilical cord blood can be procured from global public banks, the probability of finding a match for a patient of Indian origin is less than 10% because of the low inventory of available units plus the big issue of donor dropouts.

Mr. Abhaya said, Luckily, since the family was a part of LifeCells community banking programme, they could gain quick, free access to the huge inventory of over 50,000 qualified and consented units available at LifeCell, which provides greater than 97% probability of finding a match.

In majority of blood-related disorders treatable by transplants, patients own stem cells are not suitable. Hence, the best donor is a close family member, usually a sibling. However, in this case, there was only a 50% match with the sibling, thus needing a match from an unrelated donor, LifeCell said in a statement. It said while a regular stem cell transplant requires a dose of 25 million cells per kg of the patients weight, for aplastic anaemia, the recommended minimum dose is 40 million cells per kg, which is not easy to find.

The community banking model made it possible and the child received a timely transplant with an encouraging prognosis. Just 18 days after the transplant, white blood cells were completely engrafted, and platelets and red blood cell production also increased drastically, the statement added.

Dr. Pritesh Junagade, director, LOTUS Hospital, expressed surprise that the retrieval process for two cord blood units was smooth and at no additional cost to the patient as compared to other banking models.

Tasneem Bohari, the childs father, said: It was two years ago that my daughter was diagnosed with aplastic anaemia. At the time of diagnosis, the doctors had suggested she would need a stem cell transplant eventually and it would be the best possible treatment in the future.

The family did research and made enquiries about which stem cell bank to opt for as they were expecting their second child. It was during this time that their friends and relatives suggested LifeCell to them. Their doctor also suggested that they could go ahead and preserve their babys stem cell with LifeCell.

At the time of preservation, we didnt have much idea about Community Stem Cell Banking and its benefits, but today we are happy to associate with LifeCell, who have helped my daughter lead a quality life through cord blood transplant, Mr. Bohari said.

Community Cord Blood Banking allows sharing of preserved umbilical cord stem cells from a common pool amongst the members of the community. The model offers greater and easier access to donor stem cells, unlimited retrievals at the cost of one enrolment, and a higher probability for finding a close match for potentially life-saving treatments.

This facility ensures complete protection to the child, siblings, parents, and maternal and paternal grandparents from more than 80 disorders treatable by stem cells.

Results from a phase 2 study demonstrated that treatment with Jakafi (ruxolitinib) and Dacogen (decitabine) was well tolerated and contributed to favorable overall survival (OS) in patients with myeloproliferative neoplasm (MPN) in the accelerated or blast phase.

MPN is a blood cancer that develops when a stem cell mutation in the bone marrow leads to an overproduction of white cells, red cells and/or platelets. The accelerated phase of MPN refers to when 10% to 19% of blasts, or immature blood cells, are in the blood circulating through the body or in the bone marrow, whereas the blast phase refers to 20% or greater blasts in the circulating blood or bone marrow, according to the study published in Blood Advances.

This study was important, as patients with an antecedent (pre-existing) myeloproliferative neoplasm that evolves into an acute myeloid leukemia have a dismal prognosis of several months, and induction chemotherapy alone does not improve outcome unless followed by consolidation hematopoietic stem cell transplantation, Dr. John O. Mascarenhas, director of the adult leukemia program and leader of the myeloproliferative neoplasm clinical research program at Tisch Cancer Institute at Icahn School of Medicine at Mount Sinai, said in an interview with CURE.

The study authors previously assessed this therapy in a multicenter, phase 1 trial.

We had previously shown that the epigenetic modifying agent decitabine can be administered (on) an outpatient (basis) and improve outcome with a median survival of nine to 10 months, Mascarenhas said. This prospective, phase 2, multicenter, investigated-initiated trial built on the phase 1 trial of combination decitabine and ruxolitinib based on supportive preclinical data from the laboratory of our collaborator, (Dr.) Ross Levine.

In this current trial, 25 patients (median age, 71 years; 56% women) with MPN either in the accelerated phase (10 patients; median age, 70.1 years; 70% women) or blast phase (15 patients; median age, 71.6 years; 46.7% women) were treated with Jakafi and Dacogen. A 25 mg dose of Jakafi was administered orally twice per day for 28 days in addition to a 20 mg/m2 dose of Dacogen intravenously during days 8 through 12. After that first cycle, the dose of Jakafi was reduced to 10 mg.

The prespecified primary endpoint, or goal, was best response by six months, and the predetermined secondary endpoint focused on the safety and tolerability of Jakafi and Dacogen. Study authors defined OS as the time from the first dose of Jakafi to death from any cause.

During follow-up, 19 patients died from causes including respiratory failure, disease progression, sepsis and pneumonia. Patients in this study had a median OS of 9.5 months. Overall response rate, which included complete remission, incomplete platelet recovery and partial remission, occurred in 44% of patients. Response to this treatment was not linked with improved survival.

This combination is well tolerated and can provide spleen symptom benefit and survival advantage compared to cytotoxic chemotherapy, Mascarenhas said. This study supports the use of this approach to maintain ambulatory care of these very advanced patients with a limited lifespan. This is one therapeutic approach that is now included in the (National Comprehensive Cancer Network) guidelines.

Mascarenhas added that more research is needed in this area. Ultimately, we need to identify active agents that can fully eliminate the malignant hematopoietic stem cell and attain molecular remissions that afford patients long-term survival, he said. This is an ongoing area of active translational research of our group.

Egg cells harvested from Mauritian cynomolgus macaques (top left) were fertilized (top right) and injected with CRISPR gene editing materials to insert a genetic mutation that cured two men of HIV in the last decade. The growing embryos (developing in the bottom images), if carried to maturity by surrogates, will help researchers study the mutation as a potential treatment for HIV. Courtesy of Golos and Slukvin labs

A gene that cured a man of HIV a decade ago has been successfully added to developing monkey embryos in an effort to study more potential treatments for the disease.

Timothy Brown, known for years as the Berlin Patient, received a transplant of bone marrow stem cells in 2007 to treat leukemia. The cells came from a donor with a rare genetic mutation that left the surfaces of their white blood cells without a protein called CCR5. When Browns immune system was wiped out and replaced by the donated cells, his new immune systems cells carried the altered gene.

This mutation cuts a chunk out of the genome so that it loses a functional gene, CCR5, that is a co-receptor for HIV, says Ted Golos, a University of WisconsinMadison reproductive scientist and professor of comparative biosciences and obstetrics and gynecology. Without CCR5, the virus cant attach to and enter cells to make more HIV. So, in Timothy Browns case, his infection was eliminated.

In 2019, a second cancer patient Adam Castillejo, initially identified as the London patient was cleared of his HIV by a stem cell transplant conferring the same mutation.

Thats very exciting, and there have been some follow up studies. But its been complicated, to say the least, Golos says.

Between the two transplants came a more infamous application of the mutation, when in 2018 Chinese biophysicist He Jiankui announced he had used the DNA-editing tool CRISPR to write the mutation into the DNA of a pair of human embryos. His work drew criticism from scientists concerned with the ethics of altering genes that can be passed down to human offspring, and he was jailed by the Chinese government for fraud.

The promise of the CCR5 mutation remains, but not without further study. The mutation occurs naturally in fewer than 1 percent of people, suggesting that it may not be associated only with positive health outcomes. An animal model for research can help answer open questions.

Given interest in moving forward gene-editing technologies for correcting genetic diseases, preclinical studies of embryo editing in nonhuman primates are very critical, says stem cell researcher Igor Slukvin, a UWMadison professor of pathology and laboratory medicine.

Golos, Slukvin and colleagues at UWMadisons Wisconsin National Primate Research Center and schools of Veterinary Medicine and Medicine and Public Health employed CRISPR to edit the DNA in newly fertilized embryos of cynomolgus macaque monkeys. They published their work recently in the journal Scientific Reports.

Slukvins lab had already established a method for slicing the CCR5-producing gene out of the DNA in human pluripotent stem cells, which can be used to generate immune cells resistant to HIV.

We used that same targeting construct that we already knew worked in cells, and delivered it to one-cell fertilized embryos, says Jenna Kropp Schmidt, a Wisconsin National Primate Research Center scientist. The thought is that if you make the genetic edit in the early embryo that it should propagate through all the cells as the embryo grows.

Primate Center scientist Nick Strelchenko found that as much as one-third of the time the gene edits successfully deleted the sections of DNA in CRISPRs crosshairs base pairs in both of the two copies of the CCR5 gene on a chromosome and were carried on into new cells as the embryos grew.

The goal now is to transfer these embryos into surrogates to produce live offspring who carry the mutation, Schmidt says.

Cynomolgus macaques are native to Southeast Asia, but a group of the monkeys has lived in isolation on the Indian Ocean island of Mauritius for about 500 years. Because the entire Mauritian monkey line descends from a small handful of founders, they have just seven variations of the major histocompatibility complex, the group of genes that must be matched between donor and recipient for a successful bone marrow transplant. There are hundreds of MHC variations in humans.

With MHC-matched monkeys carrying the CCR5 mutation, the researchers would have a reliable way to study how successful the transplants are against the simian immunodeficiency virus, which works in monkeys just like HIV does in humans.

Anti-retroviral drugs have really positively changed the expectation for HIV infection, but in some patients, they may not be as effective. And theyre certainly not without long-term consequences, says Golos, whose work is funded by the National Institutes of Health. So, this is potentially an alternative approach, which also allows us to expand our understanding of the immune system and how it might protect people from HIV infection.

The animal model could lead to the development of gene-edited human hematopoietic stem cells the type that work in bone marrow to produce many kinds of blood cells that Slukvin and Golos say could be used as an off-the-shelf treatment for HIV infection.

This research was supported by grants from the National Institutes of Health (R24OD021322, P51OD011106, K99 HD099154-01, RR15459-01 and RR020141-01).

During a Targeted Oncology Case Based Peer Perspective event, Usama Gergis, MD, MBA, professor of Oncology, director, Bone Marrow Transplant and Immune Cellular Therapy at Sidney Kimmel Cancer Center, at the Thomas Jefferson University Hospital, discussed the case of a 48-year-old male patient with acute graft-versus-host-disease (GVHD).

Targeted Oncology: For a patient such as this, what is the risk of developing acute (GVHD) following transplant?

GERGIS: The list of risk factors for GVHD is huge: donor HLA [human leukocyte antigen] disparities that are major/minor, sex matching, donor parity, donor age, blood typewhile its controversialdonor CMV seropositivity, gene polymorphism, and stemcell graft source. Obviously, peripheral mobilized stem cells have more T cells than bone marrow. Other factors include graft composition, the higher CD34 the higher lymphocytes, and conditioning intensities. There are a bunch of factors here, at least for our patient, who had a MAC. The fact that his donor is a multirisk, 50-year-old woman and a MUD [infers] similar higher risk.

How quickly do you determine whether a patient is steroid refractory or steroid dependent?

Basically, steroid refractoriness or resistance versus dependence versus intolerance [can be determined in] as early as 3 days. If there is progression of the grade of GVHD, this is considered steroid refractory. If by 4 weeks it does not go to grade 0, its considered refractory. However, I disagree with the 28-day [timeline]. I think its a long time to wait. Usually, I look at 2 weeks.

This has been the consensus among many of us. I think the trials REACH-1 [NCT02953678] and REACH-2 [NCT02435433] looked at 28 days; but if you go to the 2 papers, most responses took place in 7 to 14 days. Again, this is in the second-line setting.

Ive been doing this for 15 years. Ive been through most of this; so many lines [of therapy and] so many heartbreaks. I teach my fellows to look at any [research] paper in second-line GVHDthe overall response rate is 30%. Ive done it with MMF [mycophenolate mofetil], sirolimus [Rapamune], infliximab [Remicade], ATG [antithymocyte globulin], cyclophosphamide, Ontak [denileukin diftitox], and mesenchymal stem cells and overall response rate is 30%.

Which data support the use of ruxolitinib (Jakafi) in patients who are steroid refractory?

Based on a small trial of 49 patients, a phase 2 trial [INCB 18424-271; NCT02953678], ruxolitinib was approved as a second-line therapy for patients with acute steroid-refractory GVHD.1

Review the details of the REACH-2 trial.

The REACH-2 trial data were just published in 2020. Ruxolitinib was approved based on a small trial of 49 patients with steroid-refractory acute GVHD. They enrolled 70 but only 49 were available for efficacy. Obviously, it was a pilot phase 2 with no comparative arm, and the response rates across the board were [somewhere in the range of] 50% or so by day 28.

Then they were asked to run a phase 3 trial comparing ruxolitinib at 10 mg twice daily versus best available care. The best available care goes through the list that I just mentioned, including photopheresis, ATG, and others. After 4 weeks, patients who were not responders on the best available care were allowed to cross over to ruxolitinib.

By day 28, the responders on the ruxolitinib composed 60% of the cohort versus 40% on the control arm with a P value of less than .001. The durability of response at 8 weeks was 40% versus 20% [odds ratio, 2.38; 95% CI, 1.43 to 3.94; P < .001].

This tell us that ruxolitinib works in this group, that it does not work that great in one-third of patients who lose their response at 8 weeks, and that its just better than anything else [thats available]. A good thing about the ruxolitinib arm is that the response duration was much longer than best available treatment, as illustrated by the Kaplan-Meier curve for response duration.

Failure-free survival [in this trial] was 5.0 months versus 1.0 month [HR, 0.46; 95% CI, 0.35-0.60].

Do you apply this therapy to any of your patients?

We have a patient [at my institution] who has steroid-refractory GVHD. Last Friday in our weekly meeting, we were discussing his [case]. He has lower GI [gastrointestinal] GVHDgrade IV, steroid-refractory, as bad as it getsand I said lets start him on ruxolitinib. One of my colleagues said it doesnt work well in the lower GI. I asked the organizers to pull [data] from the supplemental figures on the New England Journal of Medicine paper of REACH-2 [indicating that these patients did have a benefit with ruxolitinib].2

Research may lead to identifying novel therapies for cardiac patients

(New York, NY November 19, 2020) Human placental stem cells may have the potential to regenerate heart tissue after a heart attack, according to Mount Sinai researchers who have received a $2.9 million grant from the National Institutes of Health to study them. Their findings could lead to new therapies for repairing the heart and other organs.

Hina W. Chaudhry, MD,Director of Cardiovascular Regenerative Medicine at the Icahn School of Medicine at Mount Sinai, is the Principal Investigator for this four-year award.

This is very exciting. These cells may represent the ideal cell type for heart repair, which has been very challenging because clinical trials of other cell types did not find much benefit, says Dr. Chaudhry. Weve never before seen a stem cell type that can be harvested from an adult organthe placentaand has the ability to travel through the circulation and not be attacked by the immune system.

Dr. Chaudhry and a team of investigators previously discovered thatmouse placental stem cells can help the hearts of mice recover from injury that could otherwise lead to heart failure. They identified a specific type of placental stem cells, called Cdx2 cells, as the most effective in making heart cells regenerate. They discovered this by inducing heart attacks in groups of male mice and then injecting the placental Cdx2 cells isolated from females into their bloodstream. Imaging showed that the mice with Cdx2 stem cell treatments had significant improvement in cardiac function and regeneration of healthy tissue in the heart. The mice without this stem cell therapy went into heart failure and their hearts had no evidence of regeneration.

This team also found that the mouse Cdx2 cells have all the proteins of embryonic stem cells, which are known to generate all organs of the body, but also additional proteins, giving them the ability to travel directly to the injury site, which is something embryonic stem cells cannot do, and the Cdx2 cells appear to avoid the host immune response.

The new grant allows the researchers to build upon this discovery by isolating human Cdx2 cells from human placentas and studying their ability to grow heart cells. They also plan to expand into other organs and tissues in the future.

This was a serendipitous discovery based on clinical observations of patients with peripartum cardiomyopathy. We surmised that stem cells originating from the placenta may be assisting in repair of the mothers heart and designed studies to identify the cell types involved. We then showed that they work very well in male mice also when isolated from female placentas and now we hope to design a human cell therapy strategy for heart regeneration with this grant. Given that these cells maintain all the stem properties of embryonic stem cells, we are hopeful to utilize them for other types of organ repair as well, adds Dr. Chaudhry.

The grant is being used in collaboration with the Departments of Obstetrics and Gynecology and Pathology at Cedars-Sinai Medical Center in Los Angeles.

Stem cells found in the lungs can be redirected to the heart using a new inhaled antibody therapy to help boost healing following a heart attack.

Image credit: Jesse Orrico on Unsplash

Cardiovascular diseases are one of the leading causes of death globally. Medical advancements have lowered a persons risk of dying from an episode, but cell death and scar tissue that form afterward drastically increase the risk of eventual heart failure.

Stem cell therapy is a promising strategy used to help minimize long-term damage by regenerating new, healthy heart cells at damaged sites. However, their clinical application is hampered by poor cell engraftment, which comes with trying to grow new cells on a constantly moving organ.

Solutions to this have been proposed in the past, such as using durable patches to help the cells adhere to the heart surface, but a team of researchers from North Carolina State University propose that redirecting easy-to-access stem cells already found in the body could help spur repair in an injured heart.

Stem cells have become [] important for cardiomyocyte regeneration over the last two decades, wrote the team in their paper published in Advanced Science. In fact, as [part of] the bodys own repair mechanism, endogenous stem cells from the bone marrow are recruited into the heart. The issue, they point out, is that these stem cells lack the ability to properly target the heart, which hinders their ability to accumulate where they are needed.

In previous studies, the team demonstrated that heart attack biomarkers can be used to guide infused or endogenous stem cells to the site of cardiac injury. They also took advantage of cells called platelets, which help form blood clots and have an exceptional ability to target and accumulate in injured tissue.

By taking advantage of the injuryhoming ability of platelets, we can target stem cells to the [damaged] area, said the authors. [However], this strategy has a caveat: most of the bodys endogenous stem cells are produced in the bone marrow, and these cells are difficult to access.

The lung has recently been recognized as a site where both stem cells and navigator cells, such as platelets, are found in high concentrations. The team therefore sought to develop a strategy to link those two types of cells to provide an in-house treatment for repairing damaged cardiac tissue following a heart attack.

In this way, platelets can piggyback on stem cells found in the lungs called hematopoietic stem cells (HSCs) and bring them to the damaged site for repair, they said. To do this, they designed what is called a bispecific antibody, which is an artificial protein that can simultaneously bind to two different types of molecules. They are commonly used in treating cancers and different autoimmune diseases, but in the current study, the researchers used them to bind HSCs as well as platelets, to help the stem cells accumulate where they are needed.

An interesting and advantageous aspect of this strategy is the fact that the bispecific antibodies can be delivered through inhalation since their desired location is the lungs. Unlike previous strategies, this provides a safe, non-invansive, and convenient way of administration.

In the study, the team tested whether the inhaled antibodies could effectively link HSCs with platelets and redirect them to the injured heart, and bench-marked this route of administration against an intravenous infusion. It was found that the antibody therapy effectively conjoined HSCs and platelets, and the redirected stem cells helped promote repair and minimized inflammation at the site of injury, which led to increased cardiac function compared to controls. In addition, inhalation of the platelet-antibody therapy was found to be more efficient and specific than the intravenous route.

While there are limitations that still need to be overcome before this can move into clinical trials, this work demonstrates an innovative and easy approach to help boost heart healing and limit the long-term damage of heart attacks. The team is hopeful that this work can be used as a jumping point to help bring this type of treatment closer to clinical application.

It dawned on Eian Kantor on a Saturday in early April as he brewed a cup of tea from fresh mint leaves: he had lost his sense of smell. The tea suspiciously smelled of nothing at all. Kantor proceeded to rifle through the fridge, sniffing jars of pickles, chili sauce and garlicnothing.

Ever since New York State went into lockdownin late March,Kantor, age 30, and his girlfriend had stayed isolated in their Queens, N.Y., apartment. So he did not suspect he had COVID-19 despite running a slight fever that he chalked up to seasonal allergies. When he was finally able to get tested weeks into his loss of smell, or anosmia, he tested negative. But months later, he says, several tests showed that his antibodies to the novel coronavirus were off the charts high, which affirmed that I had had it.

An estimated 80 percent of people with COVID-19 have smell disturbances, and many also have dysgeusia or ageusia (a disruption or loss of taste, respectively) or changes in chemesthesis (the ability to sense chemical irritants such as hot chilies). Smell loss is so common in people with the disease that some researchers have recommended its use as adiagnostic testbecause it may be a more reliable marker than fever or other symptoms.

One lingering mystery is how the novel coronavirus robs its victims of these senses. Early in the pandemic, physicians and researchers worried that COVID-related anosmia might signal that the virus makes its way into the brain through the nose, where it could do severe and lasting damage. A suspected route would be via the olfactory neurons that sense odors in the air and transmit these signals to the brain. But studies have shown that this isprobably not the case, says Sandeep Robert Datta, a neuroscientist at Harvard Medical School. My gestalt read of the data to date suggests that the primary source of insult is actually in the nose, in the nasal epithelium, the skinlike layer of cells responsible for registering odors. It looks like the virus attacks, predominantly, support cells and stem cells and not neurons directly, Datta says. But that fact does not mean that neurons cannot be affected, he emphasizes.

Olfactory neurons do not have angiotensin-converting enzyme 2 (ACE2) receptors, which allow the virus entry to cells, on their surface. But sustentacular cells, which support olfactory neurons in important ways, are studded with the receptors. These cells maintain the delicate balance of salt ions in the mucus that neurons depend on to send signals to the brain. If that balance is disrupted, it could lead to a shutdown of neuronal signalingand therefore of smell.

The sustentacular cells also provide the metabolic and physical support needed to sustain the fingerlike cilia on the olfactory neurons where receptors that detect odors are concentrated. If you physically disrupt those cilia, you lose the ability to smell, Datta says.

In astudyinBrain, Behavior and Immunity, Nicolas Meunier, a neuroscientist at the Paris-Saclay University in France, infected the noses of golden Syrian hamsters with SARS-CoV-2. Just two days later, about half of the hamsters sustentacular cells were infected. But olfactory neurons were not infected even after two weeks. And strikingly, the olfactory epithelia were completely detached, which, Meunier says, resembled skin peeling after a sunburn. Although olfactory neurons were not infected, their cilia were entirely gone. If you remove the cilia, you remove the olfactory receptors and the ability to detect odorants, he says.

Disruption of the olfactory epithelium could explain the loss of smell. Yet it remains unclear whether the damage is done by the virus itself or invading immune cells, which Meunier observed after infection. Widespread reports of anosmia with COVID are not typical of other diseases caused by viruses. We think its very specific to SARS-CoV-2, Meunier says. In aprevious studywith other respiratory viruses at his lab, he foundsustentacular cells infected only rarely, whereas with SARS-CoV-2, about half of cells contained the pathogen. With other viruses, smell is usually compromised by a stuffed-up nose, but COVID doesnt usually cause nasal congestion. This is very different, Meunier says.

Researchers have found a few clues about the loss of smell, but they are less certain about how the virus causes a loss of taste. Taste receptor cells, which detect chemicals in the saliva and send signals to the brain,do not contain ACE2, so they probably do not get infected by SARS-CoV-2. But other support cells in the tongue carry the receptor, perhaps providing some indication of why taste goes away. (Although taste can seem to disappear with anosmia because odors are such a key component of flavor, many people with COVID truly develop ageusia and cannot detect even sweet or salty taste.)

The loss of chemical sensingthe burn of hot chilies or the refreshing sensation of mintalso remains unexplained and largely unexplored. These sensations are not tastes. Instead their detection is conveyed by pain-sensing nervessome of whichcontain ACE2throughout the body, including the mouth.

More clues to how the virus obliterates smell come from people recovering from anosmia. The majority of patients lose smell like a light switch going off and recover it rapidly, Datta says. Theres a fraction of patients that have much more persistent anosmia and recover on longer time scales. The olfactory epithelium regularly regenerates. Thats the bodys way of protecting against the constant onslaught of toxins in the environment, Meunier says.

Still, more than seven months after he first experienced anosmia, Kantor falls in the second group of patients: he has yet to detect any odors at all. Its hard because you dont realize how much you relate to smell until you lose it, he says. If the house were on fire, I wouldnt know it. Its very concerning. And then there is what anosmia does to the joy of eating. Foods that used to be good now taste meh, Kantor says.

Carol Yan, a rhinologist at the University of California, San Diego, says that anosmia poses a real health risk. It actually increases mortality. If you cant smell and taste food, it can predispose you to harm, like rotten food or a gas leak, she says. It can also cause social withdrawal or nutritional deficits.

The variation on sensory themes extends to another symptom called parosmia, a possible sign of recovery in people with long-lasting anosmia. Freya Sawbridge, a 27-year-old New Zealand woman, is such an individual. She got COVID-19 in March. After several weeks of anosmia and ageusia, when everything tasted of ice cubes and cardboard, she says, Sawbridge began to regain the most basic tastessweet, salty, sourbut no nuance of flavor, which comes from foods aromas. Chocolate tastes like sweet rubber, she says.

Then, after about five months, some odors returned but not as expected. For a while, all foods smelled of artificial strawberry flavor. But now everything smells hideous and distorted, Sawbridge says. Nothing is accurate, and the odors are all unpleasant. The smell of onions, she says, is unbearable, and a strange chemical flavor permeates everything. All my food tastes like it was sprayed with window cleaner, Sawbridge adds.

Parosmia may occur when newly grown stem cells that develop into neurons in the nose attempt to extend their long fibers, called axons, through tiny holes in the base of the skull and connect with a structure in the brain called the olfactory bulb. Sometimes axons connect to the wrong place, causing erratic smell, but the miswiring can potentially correct itself, given enough time.

That news is welcome for people such as Sawbridge. But the question she wants answered is: How long will her anosmia last? We dont know the final time course of recovery for those with anosmia, Yan says, but it is usually from six months to a year. With long-term postviral smell loss from the flu, after six months, there is a 30 to 50 percent chance of spontaneous recovery without any treatment, she adds. There have been case reports of recovery after two years. But after that, we think the regenerative capability may be hindered. And the chances of recovery are quite slim, unfortunately.

Kantor has tried every avenue imaginable to regain his sense of smell: a course of high-dose steroids to reduce inflammation; a smell-training program with essential oils; beta-carotene supplements for nerve regeneration; acupuncture. Nothing has made a difference. Yan recommends irrigation of the sinuses with budesonide, a topical steroid shown to improve outcomesin a Stanford Universitystudy of people with postflu smell loss for more than six months. Another promising treatment Yan and others areinvestigating is platelet-rich plasma, an anti-inflammatory concoction isolated from blood that has been used to treat some types of nerve damage. But with any treatment, Yan says, the results are not amazing. Its not like youll wake up and say, Wow, I can smell again. But if you can smell soap again or enjoy the taste of some foods, thats a big gain.

There is one final worrying note about anosmia: it has beenidentified as a risk factorfor some neurodegenerative diseases. After the flu pandemic of 1919, we saw an increase in the prevalence of Parkinsons disease, Meunier says. It would be really concerning if something similar were happening here.

But Yan thinks that fear is overblown. There is certainly a link between anosmia and diseases, but we think that viral-induced anosmia is [working by] a totally different mechanism, she says. Having postviral anosmia doesnt put you at higher risk for disease. These are two completely separate phenomena. That should reassure Sawbridge and Kantorand the millions of others worldwide affected with COVID-related smell loss.

Mysteries of COVID smell loss finally yield some answers - Livescience.com

The new year is always a good time to 'reset' your life and implement new and improved health and fitness habits.

Maintaining new routines isnt easy, but here are four wellness retreats around the world that will help put the architecture in place that you need to live better.

Following the opening of Revivo in Bali in 2018, the brand will be launching a new wellness retreat in the Tarn region of France, in summer 2021.

Revivo Chteau de Fiac will take over a renovated castle on a three-hectare estate, and will feature 16 bedrooms, as well as a salt cave, a spa offering massages and hydrotherapy, bootcamp circuits, and the chance to eat freshly grown vegetables from the on-site garden.

Revivo is a proponent of teaching mind-body connectivity so always incorporates physical activity such as yoga with art classes and meditation, for example.

Also opening in spring/summer 2021, Qatars Zulal Wellness Resort will be the Middle Easts inaugural full-immersion wellness destination and the worlds first centre for traditional Arabic Islamic medicine.

Operated by wellness pioneer Chiva-Som, Zulal will have 120 rooms in a Family Wellness enclave, and 60 suites and villas in a separate zone for adults-only.

Just one hours drive away from Doha International airport, the extravagant hideaway will prescribe healing methods based on centuries of knowledge provided by Islamic medicinal historians and herbalists.

Situated in northern Goa, India, Kings Mansion will join Revivo and Zulal in making its debut in 2021.

Bringing together science and genomics with Ayurvedic medicine, the cutting-edge retreat will offer six wellbeing programmes, including areas such as:

Stays are a minimum of one week and both the Shodhana and Kshipra Shodhana detox programmes require a DNA test before arrival. These tests are to determine genetic pre-dispositions for certain health conditions, thereby allowing for highly personalised treatments.

Located on Lake Constance in southern Germany, Buchinger Wilhelmi is a hotel-clinic specialising in therapeutic fasting and integrative medicine.

In September it launched a new Immunity+ programme that is designed to boost wellbeing (with the specific aim of reducing the risk of getting Covid-19), and is bookable as a 110 add-on to its fasting packages.

After guests have been given a quick blood test on arrival to make sure they dont have Covid, they then get to relax in luxurious surroundings while embarking on a calorie-restricted regime (ten days costs 2,340 per person), which includes nurse checks, consultations with a doctor, daily activities, and a menu of freshly-made vegetable bouillon and pressed fruit juices.

Dr Francoise Wilhelmi de Toledo, scientific director at Buchinger Wilhelmi, explains, When you fast, all your digestive processes are in rest. Without needing the energy to digest, all stresses are diminished and you actually need less immunity.

"During this time, you change your microbiome. You stimulate the lungs, skin, kidneys, liver and the system itself triggers autophagy an extraordinary capacity of the body to eliminate damaged cellular structures. When you fast, you activate stem cells to rejuvenate immune cells.

Avrobio has shared data on the first Gaucher disease patient to receive its gene therapy AVR-RD-02. The patient, who was stable on enzyme replacement therapy at baseline, experienced a 22% drop in a toxic metabolite after receiving AVR-RD-02 and stopping taking the standard of care.

Gaucher, like the Fabry disease targeted by Avrobios lead prospect, is currently treated using enzyme replacement therapies sold by Sanofi and Takeda, which entered the market through its takeover of Shire. However, a significant minority of patients experience physical limitations despite treatment. Negative outcomes include bone pain and spleen enlargement. Johnson & Johnsons Zavesca offers an oral alternative, but there remain unmet medical needs.

Avrobio is developing AVR-RD-02 to address those needs. The data shared as part of Avrobios R&D day mark the start of the effort to show AVR-RD-02 performs as hoped in the clinic.

Start using real-world data to advance your clinical research

Much has been written about the promise of real-world data (RWD) in life sciences, but how does it work in practice? We address this question in a new whitepaper that demonstrates the potential benefits of new RWD technologies with a proof of concept study to show how RWD can be incorporated into clinical research.

The first patient to receive AVR-RD-02 discontinued enzyme replacement therapy one month before taking the gene therapy. Three months after receiving the gene therapy, levels of Gaucher biomarker lyso-Gb1 had fallen 22%. The patients level of plasma chitotriosidase, a biomarker of cells associated with severe organ damage, was down 17%. Hemoglobin and platelets were in the normal range.

AVR-RD-02 triggered those changes without causing serious adverse events. The data drop offers an early indication that Avrobio may be able to improve outcomes by harvesting hematopoietic stem cells, adding a gene that encodes for glucocerebrosidase and reinfusing the cells back into the same patient. With enzyme replacement therapies costing healthcare systems up to $400,000 a year per patient, there is scope for AVR-RD-02 to cut the cost of treating Gaucher disease.

Avrobio shared the early look at clinical data on AVR-RD-02 alongside updates about other assets. There is now more than three years of data on some Fabry patients treated with Avrobios lead asset, putting the company in a position to plot a path to accelerated approval. Avrobio plans to submit its briefing book to the FDA by the end of the year to align on an accelerated approval strategy.

The update also covered cystinosis candidate AVR-RD-04. The first patient to receive the candidate is off oral and eye drop cysteamine 12 months after receiving the gene therapy. The number of crystals in the patients skin are down 56%, leading Avrobio to posit they may have gained the ability to make their own functional cystinosin protein.

Voters in California have approved Proposition 14, which will pump billions of dollars into the state's stem cell research program. The Associated Press called the vote on Thursday, with 51 percent of ballots for and 49 percent against.

The result will allow the state to borrow $5.5 billion from investors for its stem cell agency, the California Institute for Regenerative Medicine (CIRM). The moneywhich taxpayers will repay with interest over the next 30 yearswill enable the institute to stay open, expand its research programs, and build new facilities.

Some $1.5 billion of the money will be spent researching conditions affecting the brain and central nervous system, such as Alzheimer's, Parkinson's, epilepsy, and stroke.

Unlike specialized cellssuch as blood cells or bone cellsstem cells do not have a specific job. Think of them as the raw materials of our bodies. When they divide, they can either renew and make new stem cells, or turn into specialized cells.

Despite making headlines for years, stem cell research is still in its early stages, with some treatments that have appeared to have worked in animals now going into clinical trials. These include treatments for macular degeneration, a common cause of blindness, as well as stroke, Lou Gehrig's disease, and spinal cord injuries.

It is hoped growing stem cells into specialized cells could also one day be used to replace damaged tissue and organs, for instance by helping the pancreas produce insulin in people with diabetes.

Currently, stem bone marrow transplantation is the most common form of stem cell therapy, used to treat blood cancer patients. Stem cell therapy has also been used for grafts of corneal stem cells, as well as skin grafts for burns victims.

As well as creating treatments, stem cell research can also help scientists understand diseases. Observing the cells in a lab as they turn into specialized cells, for instance, can provide clues on how we develop certain conditions.

There are a number of stem cells: embryonic stem cells, adult stem cells, adult stem cells tweaked to behave like embryonic stem cells, and stem cells found in the amniotic fluid and the umbilical cord of babies.

The controversy around stem cell research largely lies in the use of embryonic stem cells. These are taken from human embryos in their early stages of development. Opponents have likened this to abortion, although others disagree with this stance.

Embryonic stem cells used in research come from donations from IVF clinics, where an egg is fertilized with a sperm but not implanted into a patient because it is not needed. Embryonic stem cells are preferred over adult stem cells, as it may not be possible to specialize the latter and they are more likely to have abnormalities. But research suggests that it may be possible to turn adult stem cells into a wider range of specialized cells than previously thought, which may make them more useful.

In 2001, the Bush administration banned federal funding for stem cell research. This lead real estate developer Robert N. Klein II to initiate and help fund Proposition 71 in California. The aim was to enshrine the right to carry out stem cell research in the state's constitution, and establish CIRM. Klein was motivated by his son's experience with Type 1 diabetes, and his mother's Alzheimer's diagnosis. In 2004, Californians voted in favor of the proposition.

The institute has performed 64 clinical trials, and published over 3,000 scientific articles on the subject. But 16 years after Proposition 71 passed, CIRM started to run out of funds, and stopped accepting applications for new projects last year. This prompted the Californians for Stem Cell Research, Treatments and Cures political action committee (PAC) to lead the campaign for Proposition 14. Klein was among its supporters, as well as California governor Gavin Newsom, LA mayor Eric Garcetti, and the Michael J. Fox Foundation established by the Back to the Future actor and Parkison's disease patient who is its namesake.

On November 1, the foundation urged people via Twitter to vote in favor of Prop 14 to fund research on neurological disease. "Without this proposition vital research may come to a halt, delaying new treatments for people with," it said.
