A Sweet Treatment for Diabetes

Sugar Molecule Protects Mice Against Type 1 Diabetes

a spoonful of sugar

Avoiding too much sugar is one of the cardinal rules for those who have or are at risk for diabetes. In fact, diabetes is characterized by having too much glucose, a form of sugar, in the blood. As a result, it came as quite a surprise to IRP researchers led by senior investigator Wanjun Chen, M.D., when they discovered that a particular form of sugar that they expected to have no effect on diabetes-prone mice actually protected them from developing type 1 diabetes.

Medical Research Scholars Reflect on Their NIH Journeys

Future Physician-Scientists Spent a Year in IRP Labs

Many doctors not only treat patients directly, but also make valuable contributions to research that will improve medical care in the future. Each one of these talented ‘physician-scientists’ began his or her research career under the guidance of a more senior scientist. At the NIH, the Medical Research Scholars Program (MRSP) provides just such an experience to promising young medical students from all across the United States.

Innovation Awards Spark New Intramural Collaborations

Program Boosts Initiatives Supporting Researchers Across NIH

From Superbowl-winning football teams to comic book cohorts like The Avengers, combining the efforts of multiple talented individuals is a proven strategy for achieving remarkable results. It may come as no surprise, then, that the NIH’s Intramural Research Program (IRP) strongly encourages collaborations that breach the boundaries of its 24 Institutes and Centers. One example of these efforts is the Director’s Challenge Innovation Awards Program, which since 2009 has funded high-impact scientific projects that bring together researchers from across the IRP.

Immune Cells Produce Potent Packages of Anti-Inflammatory Molecule

Experimental Treatment Curbs Autoimmune Eye Disease in Mice

B cell

Our cells produce a wide range of chemicals necessary for good health, but when they cannot manufacture enough of these substances, scientists can use cells cultivated in their labs to pick up the slack. In a promising example of this approach, IRP scientists stimulated lab-grown immune cells to produce tiny bundles of an important anti-inflammatory molecule and used those packages to successfully treat a potentially blinding autoimmune disease in mice.

IRP’s Luigi Notarangelo Elected to National Academy of Medicine

NIH Researcher Recognized for Insights into Genetic Immune System Diseases

Dr. Luigi Notarangelo

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.

Cellular Therapy Could Soothe Sarcoidosis

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.

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

NIH graduate student John Fenimore

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.
