Scientists Pinpoint Traitorous Immune Cells in Lupus

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.

IRP’s Michael Lenardo Elected to National Academy of Sciences

NIH Researcher Recognized for Enhancing the Molecular Understanding of Immune Responses

Dr. Michael Lenardo

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.

Research Symposium Celebrates Graduate Student Science

Event Spotlights Students Completing Their Ph.D. Research in IRP Labs

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.

Rare Disease Research Reveals Why Immune Cells Go Wild

Discovery Could Improve Therapy for Multiple Autoimmune Diseases

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

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.

Taming Immune Cells with a Molecular “Switch”

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.

How Asking a Very Basic Research Question Led Us to a Model For At Least 3 Diseases

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.
