In Greenland in January 2021, a child just under two years old was sickvery sick. And his doctors couldnt figure out why. He was feverish, vomiting, having seizures. Meningitis was suspected to be the cause; a tuberculosis diagnosis was also being tossed around. The child was transferred to Copenhagento Rigshospitalet, the largest hospital in Denmarkfor further evaluation.

By March, the childs doctors were no closer to figuring out why he wasnt getting better. So they reached out to Trine Mogensen, a professor of immunology at Aarhus University in Denmark. It was really unclear what this infection was. And there was no evidence of bacterial infection or tuberculosis, Mogensen says. Stumped, she and her team sequenced the childs genome to see if this uncovered any clues. It came out, surprisingly, that there was a genetic mutation, she says.

What they had found was a mutation in the gene that codes for IFNAR2, a protein that binds to type I interferons. Interferons are a family of proteins that play an essential role in fighting off viral infections. Without type I interferons working well, the child would be unable to mount any kind of immune response to viruses such as Covid-19 and the flu.

Yet what virus the child was facing was still unclear. So Mogensen got in contact with Christopher Duncan, a clinician-scientist who studies viral immunity and interferons at Newcastle University in the United Kingdom. Duncan had been researching the very same genetic mutation for several years, first documenting it in a 2015 paper in the journal Science Translational Medicine. In that paper, he and his colleagues had found the genetic variant in a family from Ireland. A 13-month-old infant had suffered a severe case of encephalitisinflammation of the brainafter receiving the MMR vaccine, which contains live (but weakened) forms of the measles, mumps, and rubella viruses. The childs illness ultimately proved to be fatal.

Following the publication of that paper, Duncan and his colleagues had been contacted by researchers in Alaska, who had identified a couple of childrenunrelatedwho had run into major problems with multiple viruses and had the same genetic variant. He was also alerted to two children in northern Canada with a similar condition.

Knowing this, Mogensen and Duncan went back to the child from Greenlandand finally uncovered the root of his condition. They discovered that three weeks before falling ill, he had also been vaccinated with the live MMR vaccine. (The child survived and is now healthy.) Duncan and Mogensen published their findings in April in the Journal of Experimental Medicine.

But now the team wanted to know if there were more people carrying this uncatalogued genetic mutation. They had noted that the boy from Greenland and the children from Alaska were all of Inuit or Alaska Native heritage. They trawled through the genetic records of 5,000 Inuit and found the variant was surprisingly common: In fact, 1 in 1,500 people in the Inuit population were carrying it. That was hugely surprising, Duncan says.

This Gene Mutation Breaks the Immune System. Why Has It Survived? - WIRED

When it comes to unlocking the secrets of DNA repair, Ranjit Bindra, MD, PhD, doesnt think in terms of just resources. The Harvey and Kate Cushing Professor of Therapeutic Radiology and professor of pathology favors a far mightier word: armamentarium. Based on the Latin word for armory, it describes the collection of medicines, equipment, and techniques utilized by a medical practitioner for a field of study.

Yale Cancer Center has an especially impressive armamentarium in the study of BRCA1 and BRCA2, proteins involved with DNA repair that, when mutated, can cause breast, ovarian, prostate, and pancreatic cancers. So when a $1 million grant became available for BRCA gene research from the Gray Foundation in 2018, a diverse team of Yale experts whose perspectives on BRCA gene-driven malignancies provide a 360-degree view from bench to bedside combined their collective skills to secure the sizable gift.

In the three years since, Yales team has made significant advances in targeting the BRCA gene-dependent DNA repair axis for cancer therapy.

Both the BRCA1 and BRCA2 protein are involved in DNA repair, said Megan King, PhD, associate professor of cell biology and of molecular, cellular and development biology, and co-leader of the Radiobiology and Genome Integrity Research Program at Yale Cancer Center. However, the work weve done has shown us that they have fundamentally different mechanisms. Thats important, because typically in clinical trials we lump together patients with BRCA1 and BRCA2 mutations. We need to think about these patient populations differently.

Those mechanisms affect which kind of therapies might work once cancer patients relapse on PARP inhibitors, a treatment that stops PARP proteins from repairing DNA damage in cancer cells and leads to cell death. For example, King has identified that if BRCA1 tumors stop expressing the 53BP1 or REV7 proteinboth of which play a role in repairing DNA double-strand breaksthey become resistant to PARP inhibitors. Thats because the absence of those proteins allows a third enzyme, called the Bloom syndrome protein (BLM), to not only resume the resection of DNA double-strand breaks, but go into repair overdrive, called hyper-resection.

Kings research identified BLM as a novel therapeutic target. She already has a candidate in mind for the job: a new class of drugs called ATR kinase inhibitors. The ATR kinase communicates DNA damage to the cell and activates DNA damage checkpoints, which arrest the cell cycle to provide time for repairs.

BLMs hyper-resection is a vulnerability that makes it sensitive to ATR inhibitors, King explained. She is working to design a clinical trial for ATR inhibitors in BRCA1 patients with fellow Gray Foundation team member Patricia LoRusso, DO, professor of medicine and associate cancer center director of experimental therapeutics.

The teams expertand a world experton BRCA2 is Ryan Jensen, PhD, associate professor of therapeutic radiology and pathology. He was the first scientist to purify and study the properties of the full-length BRCA2 protein. In collaboration with AstraZeneca, Jensen has focused on three BRCA2 reversion alleles, containing deletions in the BRCA2 gene that reactivate DNA repair functions, in tumor cell DNA from ovarian cancer patients who relapsed on a PARP inhibitor.

Hes currently researching whether these alleles alone cause resistance to PARP inhibitors and other cancer treatmentsand therefore, these studies could impact clinical management of patients harboring BRCA2 mutations. Furthermore, by leveraging genetic changes in BRCA2 directly from patients, Jensens team hopes this reverse translation approach will accelerate our understanding of why BRCA2 plays such a crucial role in responding to PARP inhibitors.

Enter Bindra, whose expertise in drug development drives the translation of these laboratory targets into patient therapies. His high-throughput testing capabilities enable him to conduct 96- and 384-well plate-based screening assays in PARP-nave and resistant cell lines. Where it used to take one day to analyze one well of a microplate, Bindra can now look at 384 tiny wells overnight and analyze the images and discover patterns automatically.

Of even greater excitement is Bindras comprehensive library of DNA repair inhibitor and damaging agents. He mixes and matches them in new therapeutic combinations to create novel compounds that can synergize or replace current PARP inhibitors.

When we do this testing in an academic setting instead of a pharmaceutical one, were able to profile all drug candidates out there and focus in an unbiased manner on the best combinations to move forward, Bindra said. This is not pie-in-the-sky scientific inquiry. Because they are clinical focused, these new combinations can be tested in clinics in a matter of one to two years.

Bindras cell lines have proven invaluable in Yales DNA repair research beyond the bounds of the Gray Foundation grant.

Faye Rogers, PhD, associate professor of therapeutic radiology, contributes her knowledge in DNA damage repair to the Gray Foundation team but is also pursuing numerous other research endeavors. She tapped the library for a cell line in her research on the use of endophytes to develop novel cancer-fighting compounds. Endophytes are fungi or bacteria that live symbiotically with plants and can produce the same natural products as their plant host. Theyre known as an untapped source for finding novel bioactive natural products.

An undergraduate student in Rogers lab collected endophytes for study while in Ecuador with Yales Rainforest Expedition and Laboratory Course. Rogers has identified one that produces a compound that inhibits DNA double-strand break repair in cancers with repair deficiencies, such as PTEN-deficient glioblastomas. Were now moving forward to come up with a synthetic version of this compound and conducting some medicinal chemistry to improve its efficacy, she said.

Rogers has returned the favor to the Bindra library. She has advised Bindas students in how to synthesize new classes of DNA repair inhibitors and damaging agents that will further expand Bindras testing capabilities of new compounds. Their teamwork is an example of the cross-disciplinary collaboration exemplified by the Gray Foundation team.

When you bring together people with different skills and perspectives, Bindra said, it adds so much more value to the conversation. And adds yet more invaluable tools to Yales DNA repair armamentarium.

Finding therapies for fragile X may depend on understanding the many ways proteins loss affects brain

Researchers at Washington University School of Medicine in St. Louis have identified a previously unknown function for the fragile X protein, the loss of which is the leading inherited cause of intellectual disability. The researchers showed that the protein modulates how neurons in the brains memory center process information, a central part of learning and memory.

Fragile X syndrome, the leading inherited cause of intellectual disability, is due to a genetic mutation that largely eliminates the fragile X protein, a critical element of normal brain development and function.

The fragile X protein modulates neuronal functions, including neurons within the so-called GABAergic system that regulates the activity of neural circuits. The proteins absence throws that system off kilter, and so far, experimental therapies designed to reset the system by compensating for the missing proteins functions have not been effective in clinical trials.

Now, researchers at Washington University School of Medicine in St. Louis have identified a previously unknown role for the fragile X protein in the GABAergic system. They have shown that the protein regulates the opening and closing of the GABA-A receptor in neurons from the brains memory center, thereby influencing how such neurons process information, a central part of learning and memory.

The findings, published May 17 in Cell Reports, indicate that the fragile X proteins role is more complex than previously thought, and that finding effective therapies may depend on a more nuanced understanding of the myriad ways loss of this protein affects the brain.

People think that since fragile X is related to the loss of a single protein, it is a simple disease that we can quickly understand and fix, said senior author Vitaly A. Klyachko, PhD, a professor of cell biology & physiology. But the reality is that the more we study, the more we understand its not simple at all. I think part of the reason why clinical trials fail may be because we dont really understand whats going on very well. It is possible that we need to fix more than one mechanism at the same time for patients to see any meaningful improvement.

People with fragile X syndrome have intellectual or learning disabilities, social and behavioral problems, and characteristic physical features such as large ears and long faces. They also often are noted for their friendly dispositions. The condition affects about 1 in 7,000 males and 1 in 11,000 females, with males typically more severely affected. The fragile X gene is located on the X chromosome, so females inherit one good and one bad copy of the gene, but males have only the bad copy. There are no treatments that address the underlying cause.

The GABAergic system is based on the transmission of gamma aminobutyric acid (GABA) from one neuron to another. When it arrives, GABA binds to a receptor molecule and triggers a cascade of events in the receiving neuron that results in suppression of the activity of that neuron. An overactive GABAergic system puts people to sleep; an underactive one is linked to depression, anxiety and epileptic seizures.

To better understand the role of fragile X protein in the GABAergic system, Klyachko and first author Pan-Yue Deng, MD, PhD, an associate professor of cell biology & physiology, studied neurons from the brains of mice with and without the fragile X protein. Specifically, they recorded the activity of key information-processing neurons controlled by the GABAergic system in the hippocampus, the brains learning and memory center. Such neurons sense the presence of GABA primarily by using the so-called GABA-A receptor.

The receptor is a channel that can open to allow negatively charged chloride ions to flow into the cell to modulate its activity. The researchers found that fragile X protein influences how much time the GABA-A receptor spends open and how much chloride it allows into the cell, thereby setting the baseline electrical charge inside the neuron. This baseline charge, in turn, affects the neurons ability to distinguish between multiple signals that arrive at nearly the same time, a critical mechanism of pattern separation essential for learning and memory formation.

The fragile X protein directly interacts with receptors that play a major role in the way neurons process information, Klyachko said. This is an additional function for the fragile X protein, and it may be an important one. These neuronal receptors are everywhere, and they control many critical brain functions.

But Klyachko cautions against assuming that these findings can be easily translated into therapies for people living with fragile X syndrome. The GABAergic system is complex, and small tweaks can have unexpected and far-reaching effects on brain function, he said.

I think there is a very strong desire an understandable one to immediately translate each discovery into a clinical trial, Klyachko said. But if we dont understand all of the functions this protein has and we try to go after one specific mechanism, it may destabilize the other ones, and the end result is that people dont get better. An entirely different approach to treating this disease may be possible, but I think we need to first understand much more about how it works. This is just the first stepping stone in a new direction.

NEW YORK--(BUSINESS WIRE)--Emendo Biotherapeutics presented the results of its next generation CRISPR-based gene editing approaches for several indications in an oral presentation and three posters at the 25th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT) held May 16-19, 2022, in Washington, D.C.

Emendo presented pre-clinical data for the treatment of ELANE-related Severe Congenital Neutropenia using an allele-specific editing approach, demonstrating the power of Emendos dual technology platforms that enable the development of a highly specific editing composition that demonstrates no off-targets and complete allele specificity. Significantly, the lack of off-target achieved by Emendos engineered and optimized OMNI nuclease also eliminated any translocations. Edited patient derived CD34+ cells differentiated normally into neutrophils both in-vitro and in-vivo, showing full engraftment and reconstitution of all blood lineages, as required for the desired therapeutic effect.

ELANE-based Severe Congenital Neutropenia, Emendos lead indication, is a devastating disease affecting pediatric patients that until now has been incurable, said David Baram, Ph.D., President & CEO of Emendo Biotherapeutics. We are excited by the potentially curative treatment developed by our team and were pleased to present our pre-clinical results for this program and other diverse applications of our dual gene editing technology platforms at this years ASGCT meeting. And of course, we look forward to the discussion generated by our discoveries around Type II CRISPR nuclease classifications that promise to be ground-breaking in the field.

Senior members of the Emendo Biotherapeutics R&D team including Chief Technology Officer Lior Izhar, Ph.D. and Executive Vice-President Research & Development Rafi Emmanuel, Ph.D. presented Emendos research on-site at the conference.

Researchers at theUniversity of Colorado School of Medicine have discovered an enzyme that regulates heart stiffness, setting the stage for developing novel treatments for heart failure.

The enzyme,histone deacetylase 6 (HDAC6), has been studied in the context of many diseases, including heart disease, but CU School of Medicine researchersTimothy McKinsey, PhD, professor of medicine in theDivision of Cardiology, andKathleen Woulfe, PhD, assistant professor of medicine in the Division of Cardiology, recently discovered a new role for HDAC6 in the regulation of myofibrils, the contractile units of the heart. The research was published May 16 in The Journal of Clinical Investigation.

When your heart is pumping and relaxing optimally, it's at a certain stiffness, McKinsey says. Stresses including aging, hypertension, and obesity can cause the heart to become too stiff, preventing it from relaxing and filling with blood efficiently,which leads to something called diastolic dysfunction. In other instances, the heart is not stiff enough, so it can't pump effectively, which leads to systolic dysfunction. Both conditions are life-threatening.

The CU researchers found evidence that HDAC6 acts on titin, a massive myofibril protein that contributes to heart stiffness. HDAC6 appears to remove a chemical modification known as acetylation fromtitin.When HDAC6 is inhibited, titin causes the heart to become stiffer; when HDAC6 is activated, the heart becomes less stiff. In the future, once cardiologists determine which type of dysfunction a patient has, it might be possible to therapeutically adjust HDAC6 enzymatic activity or levels to help the heart to pump and relax at an optimal stiffness.

Heart failure is still a huge problem that affects millions of people worldwide, McKinsey says. Even though there are medications to treat heart failure, people with the condition still often have poor quality of life and die at an alarming rate. We think this discovery could provide a novel avenue for treating heart failure through a distinct mechanism.

The progress of therapeutically manipulating HDAC6 to treat heart failure is helped along by the fact that HDAC6 inhibitors are actively being developed to treat other conditions, including neurodegeneration and cancer, though McKinsey cautionsthat the heart needs to be monitored more carefully in people receiving HDAC6 inhibitors.

"Our data suggest that in some cases, if you inhibit this enzyme, the heart might get too stiff, McKinsey says. Nevertheless, we firmly support continued clinical development of HDAC6 inhibitors, since this class of compounds holds great promise for treating a variety of devastating diseases, including certain forms of heart failure.

The CU researchers plan to continue to study the role of HDAC6 in heart stiffness, including testing HDAC6 inhibitors in preclinical models of systolic heart failure where titin is too compliant, and developing gene therapy to provide activated HDAC6 to hearts that are too stiff. Much of their work takes place in Woulfes laboratory, which is one of a handful of labs in the world that can isolate and study myofibril mechanics.

We are able to isolate proteins that direct contraction and relaxation in the heart in a way that preserves the mechanical function, Woulfe says. We can do this from tissue that's frozen, from our human heart bank, or from animals. We take away everything else except for those proteins that contract and relax. They are the fundamental basis of the function of the heart.This system enabled us to discover that HDAC6 directly regulates myofibril stiffness, most likely by deacetylating titin.

We think this is a major finding, and there's still a lot more to do, McKinsey adds. Scientific discovery is a series of building blocks, and we believe this is a key building block that allows us to understand the mechanics of the heart better at a molecular level, and also suggests therapeutic potential. We're going to keep vigorously working on the details of HDAC6 action in the heart.

This work was partially supported by theConsortium for Fibrosis Research & Translation, a program funded by the CU School of Medicine and co-directed by McKinsey. It aims to improve understanding of fibrotic diseases across various organ systems.

In addition to Woulfe and McKinsey, the other researchers on the study areYing-Hsi Lin, Jennifer Major, Joshua Travers, Sara Wennersten, Cortney Wilson, Korey Haefner, Maria Cavasin, Mark Jeong, Yu Han, Amrut Ambardekar, and Maggie Lam from the CU School of Medicine Division of Cardiology; Scott Ferguson from the Cardiovascular and Pulmonary Research Laboratory in the CU Department of Medicine; Tim Liebner and Chunaram Choudhary from the University of Copenhagen, Denmark; Zaynab Hourani and Henk Granzier from the University of Arizona; and Michael Gotthardt from the Max Delbruck Center for Molecular Medicine in Germany.

In the latest version of the Human Cells Atlas, 2,000 researchers in 83 countries have defined, one by one, some 60 million cells.

Our mission is to create a map of all human cells, says Israeli biologist Aviv Regev, who began the project in 2016 and leads the international consortium together with the German biologist Sarah Teichmann, from the Wellcome Sanger Institute in Cambridge (UK).

Regev, who is on leave from the Massachusetts Institute of Technology (MIT) and has a management position at US biotech company Genentech, says she believes the cross-continental team is halfway to its goal.

While children study some examples of cells at school such as neurons, red blood cells, white blood cells, and platelets, nobody knows how many types there really are, explains the scientist.

We didnt know how many genes we had until the Human Genome Project. This is a similar case, she says.

The Human Cells Atlas aims to catalog all cell types and their multiple subtypes, but also to locate them precisely in the human body and have a picture of the exact composition of each organ: what we are made of and why diseases arise.

Spanish immunologist Cecilia Domnguez Conde is among the main authors of the latest version, which was reported last week in the journal Science. The researchers describe the detailed profile of more than a million cells; presenting cross-referenced data from 33 organs of the human body, such as the heart, skin and lungs.

Domnguez Condes team is based at the Wellcome Sanger Institute, and has focused on the cells of the immune system.

We have discovered how cells adapt to different environments, says the immunologist, who will begin leading her own laboratory at the Human Technopole, a new research center in Milan (Italy), in June.

The diversity of cell types within the immune system is absolutely incredible, says Domnguez Conde, adding that the work had previously focused on the blood circulating in the body, while now, we study the cells in different tissues and we see new mechanisms.

The immunologist notes that there is a new generation of cancer treatments, the so-called CAR-T, in which white T lymphocyte blood cells are extracted from the patient. Then, using genetic engineering, they are redesigned in the laboratory to increase their ability to destroy cancer cells.

Biology textbooks have traditionally spoken of about 300 cell types in the human body, but the authors of the atlas have found 500 types in the last million cells analyzed. Understanding this astonishing diversity will make it possible to improve vaccines, increase the efficacy of antitumor therapies, facilitate regenerative medicine and develop new treatments for rare and common diseases, according to Regev, who now has a management position at the US biotech company Genentech.

While biology textbooks usually teach that there are about 300 cell types in the human body, the authors of the Human Cell Atlas have now found some 500 types. This new understanding, says Aviv Regev, will contribute to improving vaccines and antitumor therapies as well as regenerative medicine and new treatments for both rare and common diseases.

A mutation in a gene can cause a disease, but although all cells share the same DNA, the problem will only appear in cells that have that particular gene activated.

We have found many unexpected cells that have active disease-associated genes, says Regev.

For example, we have observed non-muscle cells in muscle tissue expressing genes that cause rare muscle diseases.

This is important, because if we want to develop treatments we need to know the cells in order to target them, explains the biologist.

Regev also highlights possible applications of these findings to regenerative medicine, a specialization that tries to rebuild damaged organs using new cells.

To get it right, we need to generate cells with the right properties. The atlas is a reference to ensure that the cells generated in the laboratory have the desired characteristics, he says.

Neuroscientist Rafael Yuste, a professor at Columbia University in New York, applauds the latest version of the atlas.

This batch of results is historic. It is one of the first salvos of what will be a torrent of studies in the next decade that will classify all cell types in the body, says Yuste, who has not participated in the investigation. The Spanish neuroscientist was the founder of BRAIN, a billion-dollar project sponsored in 2013 by then-US president, Barack Obama, to obtain a map of the human brain.

Yuste is optimistic. The new technologies, called transcriptomics, allow cells to be placed in narrow channels and trapped one by one in oily droplets, analyzing their active genes in a manner that is fast, automated and cheap.

The first steps of this strategy have been spectacular. For example, in the United States, the Allen Institute of Brain Sciences has classified all the cells in a part of the cerebral cortex of the mouse, generating for the first time a list of all the types of neurons in an area of the brain, says Yuste, who has collaborated on that project.

Yuste recalls how the father of neuroscience, Santiago Ramn y Cajal, discovered in 1888, using a rudimentary microscope, that neurons were individual cells. Now, says Yuste, it is giant consortia like his BRAIN initiative and the Human Cell Atlas doing this work.

It is a huge effort, says the professor. It will have a fundamental impact on science and medicine, since, in the end, everything that the brain, or the body, does, is cooked up between cell types.
