Mouse Study Illuminates Potential Mechanism Behind Mood and Anxiety Disorders
Tuesday, July 14, 2020
Millions of Americans suffered from depression and anxiety even before COVID-19 began upending their lives. To make matters worse, the stresses of living through a pandemic might not only worsen mental health but could also wreak havoc on the brain itself. New IRP research has found that psychological stress damages blood vessels in the brains of mice and dramatically alters the behavior of genes in certain blood vessel cells.
IRP Research Examines Pandemic From All Angles
Tuesday, July 7, 2020
The sheer number of labs and wide variety of scientific perspectives in the IRP make it particularly well-suited to combating a disease like COVID-19, which is affecting patients’ health and the world around them in a huge number of ways. IRP researchers specializing in psychology, genetics, epidemiology, and many other disciplines are pursuing an array of strategies to learn more about the novel coronavirus.
IRP Investigators Begin Hundreds of New Coronavirus-Related Studies
Monday, June 15, 2020
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
Monday, June 8, 2020
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.

Our friend and former colleague Phil Leder, among the world's most accomplished molecular geneticists, died on Sunday, February 2, at age 85. His work with Marshall Nirenberg — namely, the famed Nirenberg and Leder experiments starting at the NIH in 1964, which definitively elucidated the triplet nature of the genetic code and culminated in its full deciphering — helped set the stage for the revolution in molecular genetic research that Phil himself would continue to lead for the next three decades.
Smoking While Pregnant Affects a Woman’s Genes Differently From Her Baby’s
Tuesday, January 7, 2020
Decades of public health campaigns have made the health consequences of smoking common knowledge. However, for the few women who smoke while pregnant, the habit can affect not only their own bodies but also those of their unborn children. Intriguingly, according to a new study led by IRP researchers, so-called ‘epigenetic’ changes to DNA that can alter the behavior of genes differ significantly in smoking mothers compared to their babies, suggesting that maternal smoking may have unique, long-lasting effects on the way a child’s body functions.
Scientific Team-Up Identifies Source of Tumor Drug Resistance
Tuesday, December 17, 2019
It’s an unfortunate reality that nearly everyone knows somebody whose life has been affected by cancer. However, a discovery by two researchers who met by chance years ago might one day help more cancer patients overcome their disease. Two scientific teams led by the IRP’s Craig Thomas, Ph.D., a group leader at the NIH’s National Center for Advancing Translational Sciences (NCATS), and Daniel Starczynowski, Ph.D., of Cincinnati Children’s Hospital Medical Center, recently published a study describing a possible breakthrough in the fight against acute myeloid leukemia (AML), a form of cancer responsible for nearly 11,000 deaths per year in the United States.
Understanding Social and Behavioral Research in the IRP
Tuesday, December 3, 2019
The NIH IRP is world-renowned for its high-risk, high-reward biomedical research. While the NIH may be best known for its clinical and biomedical research on topics from cancer to allergies to addiction, IRP investigators have also produced a rich body of work conducted in the area of social and behavioral research (SBR). In this post, I will describe how SBR furthers the NIH’s goals of improving human health with some examples of the excellent work done by SBR investigators in the IRP.
Reddit “Ask Me Anything” Commemorates Breast Cancer Awareness Month
Friday, October 11, 2019
Breast cancer touches the lives of millions of Americans every year. In 2019 alone, researchers expect more than 300,000 American women to be diagnosed with breast cancer, along with more than 2,600 men. Roughly one out of every eight American women will develop invasive breast cancer at some point in her lifetime, making it the second most commonly diagnosed cancer in American women.
On October 9, in recognition of National Breast Cancer Awareness Month, the NIH Intramural Research Program (IRP) partnered with the National Cancer Institute (NCI) to host a Reddit “Ask Me Anything” (AMA) with two prominent researchers in the NCI's Women's Malignancies Branch: Stanley Lipkowitz, M.D., Ph.D., and Alexandra Zimmer, M.D. Between Dr. Lipkowitz’s extensive knowledge of the cellular and molecular pathways involved in breast cancer and Dr. Zimmer’s expertise in the development of clinical trials for breast cancer treatments, the pair were able to offer intriguing insights on topics ranging from recent advances in breast cancer treatment to genetic and environmental factors that influence risk for the disease. Read on for some of the most interesting exchanges that took place, or check out the full AMA on Reddit.
5 Questions with Dr. Francis McMahon
Thursday, October 10, 2019
Depression is one of the most common mental health conditions in the U.S., affecting nearly seven percent of American adults each year. With the increasing social and economic pressures of the modern world likely contributing to depressive symptoms, it is more important now than ever to study depression and the factors that contribute to recovery.
A number of variables contribute to an individual’s overall mental health and response to treatment, including elements of nature and nurture that have long been studied at the NIH. In a 2013 study, researchers led by IRP senior investigator Francis McMahon, M.D., set out to understand the complex genetic factors that he believed might help explain why antidepressants are less effective for African Americans with depression than for other populations. His research revealed that differences in socioeconomics and health explained most of those differences in antidepressant response, and the remaining differences were explained by differences in genetic ancestry, rather than self-reported race. The discovery that genetics play a role in this health disparity could help close the gap and improve depression treatment for African Americans.
