Saving the Skin From a Renegade Immune Reaction

IRP Study Provides Insight into Cancer Treatment’s Skin-Thickening Side Effects

Tuesday, April 9, 2024

Scientists have long dreamt of leveraging information about our genes to personalize medical treatment. However, in working towards that effort, they have increasingly discovered the importance not just of what genetic variants are present in a person’s DNA, but how active each of those genes is. Now, new IRP research suggests the possibility of using that information to personalize medical treatment for patients who experience serious skin problems after receiving a transplant of the bone marrow’s blood-producing stem cells.

IRP Researchers Leave Jargon Behind for Three-Minute Talks Competition

Thursday, July 6, 2023

scientist speaking into a megaphone

Scientific research is often said to take place in an “ivory tower” — not exactly an image associated with accessibility, trust, or empathy. Yet it is essential that members of the public be able to understand the work that researchers devote their lives to.

In recognition of that need, dozens of IRP postbacs, graduate students, and postdocs participate each year in NIH’s Three Minute Talks (TmT) competition. On June 22, this year’s eleven finalists offered clear and concise descriptions of their efforts to unfold the mysteries of proteins’ shapes, discover the lethal role of inflammation in infections, repackage cancer therapies to enhance their effectiveness, and much more.

Mouse Study Supercharges Neurons to Detect Parkinson’s Disease

Pushing Cells to Their Limits Could Enable Earlier Diagnosis and Treatment

Tuesday, March 29, 2022

If the many stories of mothers lifting cars to save their trapped children prove anything, it’s that we cannot know the true capabilities of our bodies until they are put to the test. This concept, it turns out, could be the key to much earlier diagnosis for Parkinson’s disease. By stimulating specific neurons to push them to their limits, IRP researchers were able to detect Parkinson’s in mice in its very early stages, opening up the possibility that a similar test could one day allow human patients to begin treatment before the disease has caused too much damage.

IRP Grad Students Present a Scientific Smorgasbord

Virtual Symposium Showcases Scientists-in-Training

Monday, March 8, 2021

IRP graduate students Khalin Nisbett, Julia Gross, Luis Rivera García, and Temesgen Andargie

Even in the midst of a global pandemic, life at NIH goes on. IRP researchers continue to run experiments, publish scientific papers, and train the next generation of scientists, including the many graduate students performing research in IRP labs through the Graduate Partnership Program. On February 17 and 18, more than 100 of these scientists-in-training presented their work virtually at the NIH’s 17th annual Graduate Student Research Symposium. Like last year’s entirely online Postbac Poster Day, the event overcame the constraints of COVID-19 precautions to showcase a broad range of research, including several studies focused on the novel coronavirus.

Alzheimer’s Patients Show Traces of Cellular Batteries in Blood

Biomarker Discovery Could Aid Diagnosis and Therapeutic Development

Tuesday, February 16, 2021

Our cells can’t afford to be wasteful, so they prefer to recycle broken components. However, when the mitochondria that provide their energy are damaged beyond repair, cells may have no choice but to throw them out. New IRP research suggests that more of this mitochondrial debris floats in the blood of patients with Alzheimer’s disease, potentially providing an easy, cost-effective way to diagnose or even possibly predict the illness.

Blood Test Predicts Premature Labor

First-Trimester Blood Analysis Could Enable Earlier, More Effective Intervention

Tuesday, October 20, 2020

Imagine a world in which pregnant women routinely travel to places of healing and meet with wise sages who examine a bit of their blood to divine when their babies will be born. While this may sound like something out of Greek mythology, it may soon become a reality, as IRP researchers have developed a test that was able to use blood samples taken early in pregnancy to identify women who would later deliver their babies prematurely.

Cellular Garbage Aids Quest for Alzheimer’s Blood Test

Experimental Approach Predicts Future Alzheimer’s Diagnoses

Tuesday, October 15, 2019

If you looked through my garbage, you would probably find a litany of apple cores (my favorite fruit) and a couple fundraising requests from my alma mater. Similarly, scientists can learn a lot about what is going on in cells by examining their trash. IRP researchers recently developed a blood test that may be able to predict Alzheimer’s disease years before the onset of symptoms by examining packages of waste products from neurons.

Poster Day Showcases Summer Student Science

Annual Event Shares Research by IRP’s Summer Interns

Tuesday, August 13, 2019

IRP summer intern Enat Ayele

NIH’s Natcher Conference Center was packed once again last Thursday for the annual Summer Poster Day. This year, more than 1,200 college and high school students spent their summer performing research in an IRP lab through the NIH’s Summer Internship Program. 

I navigated through the more than 900 posters presented this year to get a taste of the impressive work done by these young men and women in less than three months. If they can make these kinds of discoveries in just one summer, imagine what they might one day accomplish as full-time scientists and clinicians!

On the Cusp of Customized Concussion Care

Five Questions With Dr. Jessica Gill

Wednesday, July 17, 2019

football players

Each year, millions of Americans suffer sports-related concussions, and the number of youth suffering from these traumatic brain injuries has been rising. Blows to the head are common in sports such as football and hockey, and when these forces are strong enough to cause a concussion, they can harm the brain and impair cognitive functioning. Although concussions occur in staggering numbers, scientists do not fully understand what happens to the brain at the time of concussion or during the recovery period. However, that doesn’t mean they’re not trying.

Cholesterol Molecule Yields Insights Into Distressed Lungs

Potential biomarker may contribute to personalized treatments

Tuesday, February 5, 2019

Until recently, medical treatment has largely been one-size-fits-all, with doctors unable to separate patients into distinct groups that might benefit more or less from a particular approach. However, researchers are increasingly finding that individuals with the same disease can differ markedly in ways that might one day influence their care. A recent IRP study has identified a particular molecule that may have just such an impact for patients with damaged lungs.
