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.
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.
Narrower Research Focus Could Aid Treatment for Autoimmune Diseases

Police pursuing a dangerous criminal rely on witness descriptions of the suspect’s specific traits — height, weight, hair color, tattoos — to pick out the perpetrator from a vast population of mostly innocent individuals. Scientists can likewise distinguish between highly similar cell types using cutting-edge laboratory procedures. Using such techniques, IRP researchers have identified a particular variety of cell in a specific stage of its life cycle as a primary culprit behind the autoimmune disease known as lupus.
NIH Researcher Recognized for Enhancing the Molecular Understanding of Immune Responses
Tuesday, March 3, 2020
The National Academy of Sciences (NAS), established in 1863, is comprised of the United States’ most distinguished scientific scholars, including nearly 500 Nobel Prize winners. Members of the NAS are elected by their peers and entrusted with the responsibility of providing independent, objective advice on national matters related to science and technology in an effort to advance innovations in the United States.
IRP senior investigator Michael Lenardo, M.D., is one of four IRP researchers elected to the NAS over the past two years. At the NIH, Dr. Lenardo serves as Chief of the Molecular Development of the Immune System Section at the NIH’s National Institute of Allergy and Infectious Diseases (NIAID), where he studies how the cells in the immune system mount protective responses to various pathogens, including viruses and bacteria. A major focus of Dr. Lenardo’s work is the investigation of genetic abnormalities in the immune system, which have the potential to cause life-threatening diseases.
Event Spotlights Students Completing Their Ph.D. Research in IRP Labs
Tuesday, February 25, 2020
The NIH provides an extraordinarily rich environment for learning and honing the skills needed to pursue a scientific career. It’s no wonder, then, that Ph.D. students from institutions all across the United States and the rest of the world come here to conduct their dissertation research under the mentorship of the IRP’s many renowned investigators.
Nearly 150 of those students presented the fruits of their scientific work at the NIH’s 16th annual Graduate Student Research Symposium on Thursday, February 20. The insights they have produced on topics from cancer to autoimmune disease to environmental contaminants were supremely impressive and will likely contribute to important improvements in medical care in the future. For anyone who missed this exciting event, read on to learn about a few of the many research projects that were on display.
Discovery Could Improve Therapy for Multiple Autoimmune Diseases
Tuesday, August 20, 2019
Hiding among YouTube’s vast collection of cooking demos and funny cat videos are clips of patients and their advocates designed to raise awareness of specific diseases. It was just such a video that led IRP Senior Investigator Peter Grayson, M.D., M.Sc., to begin studying an extremely rare illness called deficiency of adenosine deaminase 2, or DADA2 for short. The recently published findings of that research could help improve treatment not just for patients with DADA2 but also many more individuals with similar ailments.
Drug Candidate Calms Overzealous Immune Response in the Eye
Tuesday, April 30, 2019
Our immune cells don’t like strangers and attack many organisms and substances that they have never seen before, including harmless ones. In autoimmune diseases, this reaction gets out of hand and our own cells are caught in the crossfire. IRP scientists have found that a new therapeutic compound can curb this sort of autoimmune carnage in the eye.

The most important step to solving any problem is to choose the right tool for the job. Just like a heavy fur coat will keep you comfortable in the Arctic but slowly roast you in the Sahara, your immune system’s response can be helpful or harmful depending on the specific invader it’s fighting off. A new IRP study has identified a molecular “switch” that shifts an important type of immune cell between two different approaches to protecting the body.

When I started this project, it was not my objective to develop a model for any specific disease, nor did I even suspect that the ultimate result would be some insight into autoimmune disease. The basic research question I was asking was why there are sequences in the 3’ untranslated region of the interferon-gamma mRNA that are more highly conserved than the coding region of the gene.
