Scientists spend years, even decades, intensely studying a specific disease or biological system, an approach that yields unrivaled knowledge. However, many important scientific questions require a deep understanding of several subjects. As a result, the IRP has numerous programs dedicated to encouraging scientists with different areas of expertise to work together.
One such program is the NIH Director’s Challenge Innovation Awards, which funds innovative, high-impact projects that require the cooperation of researchers in more than one of NIH’s Institutes and Centers. This year, the program selected six promising proposals with one foot in the disciplines of biology and medicine and another in engineering or the physical sciences.

Many parts of the country were hit by record-breaking heat this summer. Controlling temperature is not only important for staying healthy, but it's also crucial for many types of research. Grab your water bottle and sit down in a shady spot to take a look at some photos from the Office of NIH History & Stetten Museum on the theme of hot and cold.

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.
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.
Unconventional Genetic Strategy Could Enhance Production of Medical Treatments

We all have bad days on the job — your colleague keeps bugging you, your boss yelled at you for an innocent mistake, and you skipped lunch because you have 10 different deadlines coming up. Understandably, many people find it much harder to get their work done under such stressful circumstances. Microbes that produce chemicals for medicine and scientific research experience similar struggles, but a recent IRP study has found that short-circuiting their stress response makes them far more efficient at that task.
Virtual Symposium Showcases Scientists-in-Training

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.
The IRP’s Mario Roederer and Robert Seder Discuss the Science Behind the Headlines

Some say that if something’s not broken, then don’t fix it, but that doesn’t mean there’s no room for improvement. At least, those were the thoughts of IRP senior investigators Mario Roederer, Ph.D., and Robert Alan Seder, M.D., who recently found that the century-old tuberculosis (TB) vaccine is far more effective when administered via injection into a vein (IV) rather than into the skin, which has long been the standard way it is given. This major breakthrough received extensive media coverage, including a story in the New York Times. We went Behind the Headlines to get the inside scoop on this potentially life-saving discovery.
Four Questions with Dr. Niki Moutsopoulos

Our mouths are teeming with bacteria, a microbial ecosystem known as the oral microbiome. While these microbes are typically benign, under certain circumstances they can turn harmful and contribute to oral diseases such as periodontitis, a form of chronic gum disease characterized by microbe-driven inflammation of the soft tissues and bone that support our teeth. According to the Centers for Disease Control and Prevention (CDC), roughly 65 million Americans aged 30 or older have some degree of periodontitis. In its early stage, known as gingivitis, the gums become swollen and red due to inflammation, which is the body’s natural response to the presence of bacteria. If the condition worsens, it can lead to loose teeth and, eventually, bone or tooth loss.
NIH senior investigator Niki Moutsopoulos, Ph.D., head of the Oral Immunity and Inflammation Section at the National Institute of Dental and Craniofacial Research (NIDCR), studies periodontitis and aims to understand the immune system’s role in driving this destruction. In a 2018 study, she and her team of IRP researchers and outside collaborators discovered that an abnormal and unhealthy population of microbes in the mouth causes specialized immune cells, known as T helper 17 (Th17) cells, to trigger inflammation and destroy tissue, leading to periodontitis.
Five Questions with Dr. Heidi Kong and Dr. Julia Segre

When people think of skin health, they often think of protecting it from harmful UV rays or finding ways to avoid the fine lines and wrinkles that often come with aging and sun exposure. However, there are many factors and illnesses that impact skin health, including eczema, a chronic condition that affects tens of millions of Americans and causes the skin to become red and so itchy that it can interfere with patients’ sleep.
To combat such conditions, IRP researchers have spent decades investigating what causes them in humans through techniques such as immunology, genetics, molecular biology, and structural biology. In a 2014 study of healthy volunteers, IRP investigators Julia Segre, Ph.D., and Heidi Kong, M.D., M.H.Sc., used the latest genomic techniques to investigate the collection of microorganisms living on healthy human skin, known as the skin microbiome, in an attempt to understand how this collection of bacteria, fungi, and viruses may contribute to skin health. From their interdisciplinary research, the team was able to show that the array of microbes living on human skin is extremely diverse, varying greatly from individual to individual and between different areas of the body. This research opened doors for additional studies exploring how changes in the skin microbiome contribute to both common and rare skin diseases.
Four Questions with Dr. Tim Greten

There are over 100 different types of cancer, with liver, breast, and colon cancers among the most common. At the NIH, researchers across the organization have long been committed to furthering cancer research in an effort to increase the number of cancer survivors. They consistently push the boundaries of this field each day in the hopes that their work could lead to better diagnoses, better treatment, and better outcomes for cancer patients.
A 2018 study by IRP senior investigator Tim Greten, M.D., and his IRP colleagues did just that and more. Their research pushed the norms of cancer research by studying how a treatment as simple as antibiotics affects cancerous liver tumors. By utilizing antibiotics to wipe out the collection of microorganisms living in the digestive tracts of mice — known as the gut microbiome — the team identified a link between the gut microbiome and the behavior of the liver’s immune cells, which play a role in defending the organ against cancer. The IRP team ultimately showed that antibiotic treatment reduced the development of liver tumors in these ‘germ-free’ mice, and it also reduced the likelihood that tumors in other areas of the body would metastasize — or spread — to the animals’ livers, a finding that could one day prove beneficial to future cancer patients.
