Poster Sessions Celebrate Summer Science

Annual Event Brandishes the Next Generation of Clinicians and Scientists

Wednesday, August 24, 2022

A year after hundreds of high school, undergraduate, and graduate students were only able to participate from afar in NIH’s 2021 Summer Internship Program, IRP researchers were excited to welcome some of the program’s 2022 participants to campus. Regardless of whether they were working in the lab or remotely, these budding scientists received a full-time immersion into the world of IRP science and, surely, learned a great deal from the mentorship of NIH’s many world-renowned researchers.

To celebrate the interns’ hard work, NIH’s Summer Poster Days on August 3 and 4 gave more than 600 of them the opportunity to virtually present posters explaining their projects. With so many bright young men and women displaying the fruits of their scientific labors, it was difficult to select just a handful to highlight in this blog. Read on to learn about how five of NIH’s 2022 summer interns shed light on topics from the microbes living on our skin to the blood-clotting platelets that flow through our veins.

Designer Drug Uses Double Whammy to Fight Heart Disease

Custom-Built Molecule May Improve On Its Natural Counterpart

Monday, February 22, 2021

plaque buildup in an artery

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.

Modified Hormone Protects Damaged Hearts

Alteration Helps Prospective Drug Persist Longer in Rodents’ Bodies

Even the best construction crew cannot repair a building if it is called away from the site before it can begin its work. Similarly, while the body’s ability to cleanse itself of chemicals can prevent the buildup of toxins, it can also stymie the therapeutic effects of medications. IRP researchers recently found that modifying a prospective treatment for heart failure to help it persist longer in the body boosted its beneficial effects in mice.
