Every kid’s first gift from their mom is half of her DNA, but nearly a third of children born nowadays miss out on a bonus present. That’s because babies born via vaginal delivery are exposed to the microorganisms that live in the vagina, but infants born via Cesarian section are not. A new IRP mouse study suggests that an intervention designed to make up for this missed opportunity could reduce the risk of certain health problems that are more common in babies born via C-section.

IRP’s Giorgio Trinchieri Elected to National Academy of Sciences

IRP Scientist Has Found New Ways to Wield the Immune System Against Cancer

Dr. Giorgio Trinchieri

Over the past twenty or so years, we’ve seen a sea change in many cancer therapies resulting from advances in immunotherapy. Rather than trying to poison cancer cells with chemotherapy or rip apart their DNA with radiation, these treatments help our own bodies attack the disease. As a result, we’ve seen a remarkable reduction in cancer deaths from many types of tumors. 

NIH Distinguished Investigator Giorgio Trinchieri, M.D., has long stood at the forefront of these discoveries. This year, he was elected to the National Academy of Sciences (NAS) for his achievements in identifying the mechanisms regulating the activity of certain classes of immune cells and how the environment around a tumor interacts with the immune system to suppress an immune response to the disease. This includes searching for ways to expand the benefits of immunotherapy to more patients.

IRP Scientists Sound Off in Three-Minute Talks

Annual Competition Tests Researchers’ Communication Skills

Many scientists say that English is the international language of science, but if it is, it’s a form of English that many fluent English speakers might have trouble understanding. From ‘allosteric modulator’ to ‘zinc finger nuclease,’ the words that scientists use to talk about what they do can sound like a foreign language.

Fortunately, many current and upcoming scientists are making it a priority to learn how to communicate with people who don’t share their deep knowledge. As part of this effort, NIH’s annual Three-Minute Talks (TmT) competition brings forth dozens of IRP postbacs, graduate students, and postdocs to talk about their research to an audience of peers outside their own labs. On June 27, this year’s 11 finalists delivered clear, engaging, and — most importantly — short talks on topics ranging from skin bacteria to saliva.

Postbac Poster Day Presents a Buffet of Biology

Young Scientists Demonstrate Fruits of Their IRP Research

There’s nothing quite like visiting NIH’s Postbac Poster Day to boost your faith that the future of biomedical science is bright. On May 1 and 2, more than a thousand recent college graduates participating in NIH’s Postbac program showed their colleagues, friends, and family the fascinating projects they’re working on in IRP labs. From delving into the aging brain to making sense of the bacteria on our skin, these aspiring researchers demonstrated that they have the passion needed to unravel the most complex mysteries of human biology. Read on to learn about the scientific questions just a few of them have been doggedly investigating over the past year.

Taming Inflammation in the Intestines

IRP’s Warren Strober Breaks Down the Causes of Inflammatory Bowel Disease

For many, the holiday season brings expectations of delicious meals and treats with family and friends, but the nearly 1.6 million Americans who have inflammatory bowel disease (IBD) may need to skip these delights or endure serious digestive distress. It’s fitting, then, that the first week of December is Crohn’s and Colitis Awareness Week, an occasion that calls attention to the two conditions lumped together under the umbrella of IBD.

Of course, no awareness week is needed to remind IRP senior investigator Warren Strober, M.D., of the importance of learning more about those two conditions. An expert in how the immune system operates within the digestive system, Dr. Strober has spent decades looking for ways to provide relief for IBD sufferers.

Poster Sessions Celebrate Summer Science

Annual Event Brandishes the Next Generation of Clinicians and Scientists

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.

A Computational Approach to Curbing Chemotherapy’s Side Effects

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

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.

Graduate Student Symposium Spotlights Future Scientists

IRP’s Ph.D. and Medical Students Present Research at Virtual Event

The IRP isn’t concerned only with discovering the secrets of how our bodies work and developing new therapies to treat disease. Senior scientists and many other employees at NIH also are actively involved in training the next generation of researchers. One place where the benefits of those efforts is strikingly clear is at NIH’s annual Graduate Student Research Symposium, where graduate students performing research in NIH labs show of the fruits of their partnerships with IRP researchers.

On February 16 and 17, more than 100 of the IRP’s graduate students presented their work virtually at the 18th edition of the event. These young scientists discussed the results of studies on a huge range of topics, from how hunger changes during pregnancy to how viruses cause cancer. Read on to learn about a small sampling of the projects they’ve been hard at work on.

New Lasker Scholars Begin Breaking New Ground

Early-Career Scientists Power Through Pandemic to Launch Labs

NIH’s 2021 Lasker Clinical Research Scholars

NIH has long prided itself on its ability to accelerate the careers of the brightest young physicians and scientists in the country. One of these many efforts is the Lasker Clinical Research Scholars Program, which provides a select group of individuals relatively early in their scientific careers with the funding and institutional support to start their own labs at NIH. After five to seven years of independent research in the IRP, Lasker Scholars are given the option to apply for three years of funding for work outside of NIH or to remain as investigators at NIH.

While launching a lab in the midst of a global pandemic is no easy task, five Lasker Scholars have done just that over the past year. Their research on cancer, Parkinson’s disease, childhood blindness, and inflammatory conditions is now well underway and promises to eventually improve the lives of many patients. Keep reading to learn more about how NIH’s newest Lasker Scholars are changing the way we treat those illnesses.
