Designer Drug Uses Double Whammy to Fight Heart Disease

Custom-Built Molecule May Improve On Its Natural Counterpart

Ten years ago, a young woman from Chicago came to the National Institutes of Health with a rare genetic condition. A mutation in her DNA was making her metabolic system malfunction, causing levels of fat molecules called triglycerides in her blood to skyrocket far out of the normal range. This triggered inflammation in her pancreas, a painful and potentially life-threatening condition known as pancreatitis. She couldn’t understand why there wasn’t any kind of treatment to help her.

IRP senior investigator Alan T. Remaley, M.D., Ph.D., took on the challenge with the help of Anna Wolska, Ph.D., a research fellow in his lab. Dr. Remaley leads the Lipoprotein Metabolism Section in the National Heart, Lung, and Blood Institute (NHLBI), where he and Dr. Wolska study lipoproteins, small particles that transport fats such as cholesterol and triglycerides through the bloodstream to be broken down and used by cells for energy. Their efforts to help that young woman ultimately led to the discovery — published last January — of a new strategy for reducing triglycerides in order to treat serious ailments like pancreatitis and heart disease.

Introducing NIH’s Newest Lasker Scholars

Program Gives Boost to Early Stage Investigators

If TV shows like The Voice and America’s Got Talent are any indication, there are many extremely talented people out there who could become huge successes if presented with the right opportunity. This is no less the case in science, with thousands of extremely bright individuals quietly toiling away in their mentors’ labs as they await the chance to establish research programs of their own.

Fortunately, initiatives like the NIH’s Lasker Clinical Research Scholars Program exist to boost promising young researchers on to the next stage of their careers. Every year, the Lasker program allows a small group of early stage physician-scientists to establish their own labs at the NIH and carry out independent clinical research there for at least five years.

The five talented investigators selected as 2020 Lasker Scholars are pursuing a wide range of research questions, from how the immune system influences blood clotting to the mechanisms driving a rare and devastating skeletal disorder. Read on to learn more about the latest crop of researchers ramping up IRP labs of their very own.

Psychological Stress Damages Brain’s Blood Vessels

Mouse Study Illuminates Potential Mechanism Behind Mood and Anxiety Disorders

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.
