NIH Researcher Recognized for Investigation into Genomic Stability
The National Academy of Medicine (NAM), first established in 1970 by the National Academy of Sciences as the Institute of Medicine (IOM), is comprised of more than 2,000 elected members from around the world who provide scientific and policy guidance on important matters relating to human health. Election to the NAM is considered one of the highest honors in the fields of health and medicine and recognizes individuals who have not only made critical scientific discoveries but have also demonstrated a laudable commitment to public service.
IRP senior investigator Andre Nussenzweig, Ph.D., was one of four IRP researchers recently elected to the NAM. Dr. Nussenzweig leads the Laboratory of Genome Integrity at the National Cancer Institute (NCI), where he studies how cells repair a form of DNA damage called a double strand break (DSB). This type of insult, which severs both strands of the double-stranded DNA molecule, is one of the most dangerous. If not repaired properly, DSBs can kill cells or cause DNA to rearrange in ways that are associated with cancer. Moreover, while DSBs can be caused by chemotherapy drugs and radiation, they can also happen by random chance during the course of normal cellular processes. Intriguingly, not all parts of the DNA molecule are equally susceptible to this form of damage.
IRP Study Examines Overlooked Contributor to Racial Health Disparities
Recent news coverage of the deaths of George Floyd, Ahmaud Arbery, and Breonna Taylor, along with statistics reporting startlingly disproportionate death rates among black Americans infected with COVID-19, have made it clear that racial biases can be a matter of life and death. Meanwhile, it can be easy to overlook other, more subtle ways that discrimination can affect health, such as new IRP research that links instances of discrimination to poor sleep.
IRP Investigators Begin Hundreds of New Coronavirus-Related Studies
Within just a few months after COVID-19 began spreading in the United States, IRP researchers had already made numerous important contributions to the fight against the deadly virus. Scientific knowledge about the disease continues to expand at a unprecedented pace, and the IRP will continue to play a major role in this effort over the coming months and years. In fact, nearly 300 new intramural research projects related to the novel coronavirus are currently starting up or have already begun.
NIH Researcher Recognized for Insights into Genetic Immune System Diseases
The National Academy of Medicine (NAM), first established in 1970 by the National Academy of Sciences as the Institute of Medicine (IOM), is comprised of more than 2,000 elected members from around the world who provide scientific and policy guidance on important matters relating to human health. Election to the NAM is considered one of the highest honors in the fields of health and medicine and recognizes individuals who have not only made critical scientific discoveries but have also demonstrated a laudable commitment to public service.
IRP senior investigator Luigi Notarangelo, M.D., was one of four IRP researchers recently elected to the NAM. As the head of the Immune Deficiency Genetics Section and the Laboratory of Clinical Immunology and Microbiology at the National Institute of Allergy and Infectious Diseases (NIAID), Dr. Notarangelo investigates the cellular and molecular roots of genetic conditions called primary immune deficiencies that compromise the immune system. These illnesses leave patients — many of whom are children — highly vulnerable to infections and can also lead to autoimmune problems caused when the immune system attacks the body’s own tissues. Some of Dr. Notarangelo’s patients have known genetic mutations, while for others the source of their disease remains a mystery.
Mouse Study Supports Potential of Ketone-Elevating Treatment
Whether from candy, soda, or fruit, sugar is the preferred source of sustenance for many people, and also for their brains. However, in patients with Alzheimer's disease, brain cells are less capable of turning sugar into energy. New IRP research provides evidence that this problem and the cognitive symptoms it causes could be partially solved by providing the brain with an alternative fuel.
IRP Vaccine Research Stretches Back to the NIH’s Birth
Over the past few months, the world has gained a new appreciation for the long, difficult process of producing vaccines as it waits anxiously for one that will provide protection from the novel coronavirus. With the NIH Vaccine Research Center’s efforts to develop a COVID19 vaccine drawing a huge amount of media attention, it is easy to forget that the IRP has been making vital contributions to vaccine development for more than 100 years. These efforts have helped produce vaccinations for smallpox, rubella, hepatitis A, whooping cough, human papillomavirus (HPV), and several other diseases. Read on for a visual journey through the history of IRP vaccine research.
Scientists Parse Wide-Ranging Effects of Endometrial Cancer Mutation
The so-called ‘butterfly effect’ supposes that a butterfly flapping its wings in Brazil can cause a tornado in Texas. While the jury is still out on insect-induced natural disasters, it is clear that a single genetic mutation can have wide-ranging and unexpected consequences throughout a cell. By examining the ripple effects caused by changes in a particular gene, IRP researchers have identified a potential treatment target for a particularly deadly variety of cancer.
Hundreds of Young Researchers Present Their Work Online
The COVID-19 pandemic has dramatically altered the way scientists are doing their work. Nevertheless, scientific research is a highly collaborative and interactive enterprise, so it remains essential for researchers to share and discuss their ideas and discoveries.
Every spring, the NIH’s Postbac Poster Day offers recent college graduates participating in the NIH’s Postbaccalaureate IRTA program the chance to show off the fruits of their labors and talk about their projects with both their fellow postbacs and the NIH’s many seasoned scientific veterans. Due to the need to maintain social distancing, the NIH's Office of Intramural Training and Education (OITE) went through considerable effort to move this year’s Postbac Poster Day to an online forum. The OITE staff's hard work paid off handsomely, with more than 870 postbacs presenting their research via WebEx on April 28, 29, and 30. Keep reading for a few examples of the fascinating scientific questions NIH’s latest crop of postbacs has been investigating.
Cells From Bone Marrow Calm Damaging Immune Response
In patients with the inflammatory disease sarcoidosis, the body’s own immune cells rampage around the body like The Incredible Hulk set loose in a city, attacking both harmful pathogens and our own tissues. However, just like the Black Widow can calm The Hulk down and return him to human form in the Avengers films, cells isolated from our bone marrow may be able to change certain immune cells from a damaging state to a benign one, according to new IRP research.
New Studies Will Help Efforts to Contain and Treat COVID-19
Most of the time, science is a slow process, with many experiments taking years to yield results. However, as endeavors like the Manhattan Project have shown, scientists can dramatically accelerate the pace of discovery when necessary. Over the past few months, the novel coronavirus pandemic has spurred a burst of research from scientists around the world, including numerous IRP studies. Read on for a round-up of the latest IRP COVID-19 research and learn how IRP investigators are assisting in the fight against the novel coronavirus.
