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.

Postdoc Profile: From Bench to Bedside and Back Again

Dr. Stefan Barisic Turns Laboratory Discoveries into Kidney Cancer Treatments

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.

Leveraging Turncoat Immune Cells to Combat Cancer

IRP Researchers Develop Drug to Recapture Immune Cells Hijacked by Tumors

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

Yasmin Ali

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

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.

NIH Mourns the Passing of Joost J. Oppenheim

Joost J. Oppenheim, M.D.

The IRP community is profoundly saddened by the recent passing of Joost “Joe” Oppenheim, M.D., Senior Investigator and Head of the Cellular Immunology Section in the Cancer Innovation Laboratory at NIH‘s National Cancer Institute (NCI). He died on May 14, 2022, at the age of 87.

Dr. Oppenheim was engaged in cellular immunology research at NIH for five decades and was instrumental in the discovery of cytokines, chemokines, and alarmins, which are substances produced by immune cells that enable them to communicate and act as ‘first responders” to injury or infection.

Pain Research Center Accelerates IRP Pain Studies

Dedicated Staff and Cutting-Edge Technology Helps Solve Pain’s Many Mysteries

For such a common ailment, pain remains a significant mystery. Part of the challenge of studying it is that it occurs in so many conditions and can vary from a mild ache to life-altering misery. Fortunately for both pain patients and IRP researchers studying pain, the NIH Pain Research Center has the technology and expertise to power new discoveries about pain in its many, complex forms.

On March 31 and April 1, NIH’s National Center for Complementary and Integrative Health (NCCIH) hosted a two-day virtual symposium titled “Tackling Pain at the National Institutes of Health: Updates From the Bench, the Clinic, and the New NIH Pain Research Center,” which featured presentations from a number of IRP scientists exploring important questions related to pain. Read on to learn more about some of the research discussed during that event, including efforts examining pain in patients with rare diseases, early-phase clinical trials of a new pain treatment, and investigations of how psychological factors can affect the way people experience pain.

Restoring the Flow of Precious Saliva

IRP Researchers Aim to Regenerate Damaged Salivary Glands

It’s easy to take our saliva for granted. Most people have so much of it that they think nothing of spitting it out into a trash can when they finish chewing a stick of gum. Perhaps only people who have lived without it truly understand the great gift that is a perpetually moist mouth.

“Persistent dry mouth causes lots of problems with quality of life, and people forget how important saliva is until they lose it,” says IRP senior investigator Matthew Hoffman, B.D.S., Ph.D.

In honor of World Oral Health Day on March 20, a celebration of scientific efforts to reduce the burden of oral disease, I talked with Dr. Hoffman about his lab’s efforts to understand the biology of salivary gland dysfunction and translate that knowledge into treatments that bring relief to the many people suffering from it.

Graduate Student Symposium Spotlights Future Scientists

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.
