African Ancestry May Influence Immune Response to Prostate Cancer

IRP Study Could Help Explain Racial Disparities in Disease Outcomes

Tuesday, July 19, 2022

Even as advances in therapy are extending the lives of many cancer patients, there are still stark differences in how likely patients of different races and ethnicities are to die from the disease. A recent IRP study suggests that a weaker immune response against cancer could explain the worse clinical outcomes for Black men with prostate cancer, pointing to potential strategies that could help close this gap.

Three-Minute Talks Showcase Smooth-Talking Scientists

IRP Researchers Engage and Educate at Competition Finals

Wednesday, July 13, 2022

Three-Minute Talks poster

English is generally considered the ‘international language of science,’ since nearly all scientific papers are published in English. Yet, even to a native English speaker, scientists seem to be using another language entirely to talk about their research. Most Americans, after all, don’t know an ‘autophagosome’ from a ‘lysosome’ and would be hard-pressed to explain the difference between an ‘oocyst’ and a ’sporozoite.’

Fortunately, efforts like NIH’s annual Three-Minute Talks (TmT) competition are helping scientists learn how to communicate about their research in a manner that is much easier to understand. On June 30, after months spent whittling down dozens of competitors from across the IRP, 10 finalists raced against the clock to explain their work and its importance in a clear and compelling way.

Mining Medical Data to Improve COVID-19 Treatment

Study Reveals Medications Associated With Lower Odds of Severe Infection

Tuesday, June 28, 2022

Many researchers studying COVID-19 have spent the past two years poring over test tubes and isolated cells. However, large troves of data about people’s interactions with the healthcare system can also be a rich source of useful insights. Using one such database, IRP researchers found that older adults taking certain medications were less likely to catch COVID or experience severe repercussions from the virus.

Postdoc Profile: From Bench to Bedside and Back Again

Dr. Stefan Barisic Turns Laboratory Discoveries into Kidney Cancer Treatments

Wednesday, June 22, 2022

Dr. Stefan Barisic

The Laboratory of Transplantation Immunotherapy sits at the heart of the NIH Clinical Center, just down the hallway from the Southeast inpatient unit. Here, IRP postdoctoral research fellow Stefan Barisic, M.D., labors at the bench with the goal of creating practical treatments for kidney cancer patients. Having such proximity to his patients was one of the chief attractions of working at NIH for Dr. Barisic.

“The NIH Clinical Center is an amazing place because it has all the resources you need to go from the bench to the bedside and back to the bench all in one building,” says Dr. Barisic.

Treating Parkinson’s Disease with Pinpoint Precision

Drug Candidate Could Slow Progression and Reduce Side Effects

Wednesday, June 15, 2022

If you know someone with Parkinson’s disease, you’re probably familiar with the progressive tremors and movement difficulties it causes. Unfortunately, the most common treatment for the disease — a drug called levodopa, or L-DOPA for short — can make some movement problems worse when taken for long periods of time. That’s why IRP senior investigator David R. Sibley, Ph.D., and postdoctoral fellow Amy Moritz, Ph.D., have taken on the challenge of discovering new drugs that could be given to patients in conjunction with existing treatments to more effectively slow the disease’s progression while reducing side effects.

Therapeutic Strategy Protects Heart From Diabetic Damage

Mouse Study Points to Approach for Preventing Diabetes-Related Heart Failure

Tuesday, June 7, 2022

Our cells love to lap up sugar from our blood, but as is often the case, too much of a good thing can cause problems. In people with diabetes, chronically high blood sugar can harm organs, including the heart. In an effort to combat this life-threatening problem, IRP researchers demonstrated in mice that activating a specific biological pathway in heart cells can reduce diabetes’ damaging effects on the vital organ.

Leveraging Turncoat Immune Cells to Combat Cancer

IRP Researchers Develop Drug to Recapture Immune Cells Hijacked by Tumors

Friday, June 3, 2022

macrophage

In the 1958 cult classic The Blob, a giant gelatinous creature from outer space lands on Earth and begins engulfing a small town and everything in it. While that may sound far out, a similar entity within our bodies does much the same thing, but for good instead of ill. These Pac-Man-like blobs are called macrophages — Greek for ‘big eaters’ — and they serve a vital role in keeping us healthy by clearing away dead cells and digesting foreign invaders like bacteria and cancer cells.

However, cancer cells aren’t content to just let themselves be eaten. They have evolved ways to overwhelm and commandeer the immune system, redirecting immune cells to support tumor growth rather than suppress it. Although highly personalized ‘immunotherapies’ that reboot the immune response and harness it to fight cancer have made significant advances in treating some forms of the disease, most cancers do not respond to these treatments. Fortunately, reinforcements are on the way: IRP senior investigators Udo Rudloff, M.D., Ph.D., and Juan Marugan, Ph.D., have identified a way to reclaim the loyalty of macrophages that are aiding and abetting tumors, turning them back into the cancer-consuming gluttons they were meant to be. Importantly, this approach may be effective on a broader array of cancers than other immunotherapies.

Poster Days Spotlight Young Researchers

Budding Scientists Showcase Research at Annual Event

Wednesday, May 25, 2022

Any scientist who wants to make game-changing discoveries has to start somewhere — even Albert Einstein worked in a patent office before landing his first job in academia. Through its Postbaccalaureate IRTA program, NIH hopes to give aspiring scientists more of a leg up than Einstein had by bringing them into IRP labs after they complete their undergraduate studies.

On April 26, 27, and 28, more than 900 recent college graduates participating in the program presented at this year’s virtual Postbac Poster Days. Read on to learn about a few of these young researchers and their contributions to the groundbreaking work being done at NIH.

Award Honors Promising Female Scientists

Women Scientists Advisors Select Three Young Researchers for Recognition

Thursday, May 19, 2022

Dr. Sally Chang

While women have now overtaken men in terms of admission and enrollment in undergraduate education, they remain underrepresented in the sciences. This includes at NIH, where 74 percent of senior investigators and 54 percent of tenure-track investigators are male, according to the most recent statistics available. Consequently, NIH is putting considerable effort into supporting women scientists at all stages of their careers.

One NIH entity dedicated to this important work is the NIH Women Scientists Advisors (WSA), a group of women elected to represent the interests of women scientists in the IRP. Among its many initiatives, each year the WSA chooses several female postdoctoral fellows or graduate students in the IRP to receive the WSA Scholar Award in recognition of their outstanding scientific achievements. The awardees present their research at the annual WSA Scholars Symposium, which this year was held on April 25 and recognized young women leading efforts to better understand how disease-related genes evolved, an investigation of how a fatty liver can give rise to liver cancer, and the evaluation of a way to deliver gene therapy for a rare genetic disease. Read on to learn more about this year’s WSA Scholars and the impressive discoveries they have made during their time in the IRP.

A Computational Approach to Curbing Chemotherapy’s Side Effects

Study Identifies Compounds That Could Aid Body’s Removal of Toxic Cancer Drugs

Tuesday, May 17, 2022

When it comes to cancer, the treatment can sometimes feel worse than the disease. Not only do chemotherapy drugs cause grueling side effects, but certain products made by otherwise benign bacteria living in our digestive system can interfere with the body’s ability to get rid of those toxic chemicals. A new IRP study used a cutting-edge computational approach to help identify compounds that inhibit one of those meddling bacterial molecules, which could eventually lead to the creation of medications that reduce some of chemotherapy’s side effects.
