Postdoc Profile: Eavesdropping On Bacterial Banter

Dr. Tiffany Zarrella Examines Communication Between Bacteria to Combat Persistent Infections

Dr. Tiffany Zarella

Facebook’s nearly 3 billion users may seem like a huge social network, but it pales in comparison to the conversations among the trillions of microbes that live inside a single human body. Few people know this better than IRP postdoctoral fellow Tiffany Zarrella, Ph.D., who spends her days eavesdropping on the messages bacteria send to one another to improve treatment for stubborn infections.

Dr. Zarrella was drawn to the bacterial world in microbiology lab courses while earning a biochemistry degree at Syracuse University in New York. After graduation, she obtained a research technician position at Albany Medical College, where she worked on projects centered around infectious bacteria and how they respond to their environments. She continued this thread of research in graduate school, moving on to a new study to discover how Streptococcus pneumoniae bacteria, which often cause ear infections and pneumonia, use a particular signaling molecule to resist antibiotic treatments and evade vaccines.

Leading the Charge Against Infectious Disease

Government Awards Recognize H. Clifford Lane’s Four Decades of Research Achievements

Dr. H. Clifford Lane

The remarkable career of H. Clifford Lane, M.D., might have gone very differently if a NIH scientist hadn’t accidentally eavesdropped on Dr. Lane’s conversation with a colleague in 1979. After hearing Dr. Lane mention that he had missed the deadline to apply for a position at NIH, the NIH researcher made some calls and discovered a spot there had just opened up — one that was perfect for Dr. Lane, who would spend the ensuing decades conducting life-saving research to understand and combat some of the world’s most dangerous infectious diseases.

Now the Clinical Director at the National Institute for Allergy and Infectious Disease (NIAID), Dr. Lane has been named a finalist for the 2022 Samuel J. Heyman Service to America Medals’ Career Achievement Award in recognition of his crucial contributions to the fight against HIV/AIDS, Ebola, COVID-19, and other illnesses. Also known as the “Sammies,” the awards recognize federal employees who are “breaking down barriers, overcoming huge challenges, and getting results.”

African Ancestry May Influence Immune Response to Prostate Cancer

IRP Study Could Help Explain Racial Disparities in Disease Outcomes

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.

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.

IRP’s Carolina Barillas-Mury Elected to National Academy of Medicine

NIH Researcher Recognized for Important Insights Into Malaria Transmission

Dr. Carolina Barillas-Mury

In many parts of the world, the high-pitched buzz of a mosquito is a harbinger of more than an annoying itch — it’s a warning of possible malaria infection. Malaria, a disease spread by mosquitos that causes high fever and flu-like illness, is a serious risk for nearly half of the world’s population. According to the World Health Organization, there were 241 million cases of malaria and 627,000 deaths in 2020 alone. More than 95 percent of them occurred in Africa.

Efforts to combat malaria using measures like preventative treatments and environmental mitigation have helped to reduce infections and deaths over the past decade, but those improvements have recently plateaued, according to IRP Distinguished Investigator Carolina Barillas-Mury, M.D., Ph.D., section chief in the Laboratory of Malaria and Vector Research in the National Institute of Allergy and Infectious Diseases (NIAID).

IRP’s Steven Rosenberg Receives HHS Secretary’s Award for Distinguished Service

Groundbreaking Immunotherapy Research Revolutionizes Cancer Treatment

Dr. Steven Rosenberg

Like many young boys, IRP senior investigator Steven A. Rosenberg, M.D., Ph.D., initially believed he would grow up to become a cowboy, a dream he shared with his older brother, Jerry. That plan changed after World War II ended and stories began coming out of Europe about members of his family who had perished in concentration camps.

“I just became so upset about the evil that people could perpetrate on one another,” he recalls. “Right then and there, I knew I wanted to do the opposite. I wanted to do things that would help people, and I developed almost a spiritual desire to become a doctor.”

He ultimately did become a doctor, and his pioneering research into how cancer interacts with the immune system has led to treatments that are reducing suffering for many people with cancer. In recognition of this groundbreaking work, Dr. Rosenberg was awarded the HHS Secretary’s Award for Distinguished Service in August 2021. The highest honor given by the US Department of Health and Human Services (HHS), the award celebrates excellence in leadership, ability, and service.

Postdoc Profile: COVID-19 Provides New Opportunities for Virus Science

Dr. Alberto D. López-Muñoz Pivots to New Research Focus Amidst Pandemic

Dr. Alberto D. López-Muñoz

Like all virologists, IRP postdoctoral fellow Alberto D. López-Muñoz, Ph.D., knew a global pandemic was sadly inevitable. No one could predict exactly when, but it was just a matter of time until a novel virus would make its way around the globe. Nevertheless, when the COVID-19 pandemic hit, caused by a virus called SARS-CoV-2, even Dr. López-Muñoz was surprised by how rapidly his career transformed as he switched gears study the novel contagion.

IRP Grad Students Present a Scientific Smorgasbord

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.

IRP’s John T. Schiller Elected to National Academy of Sciences

NIH Scientist’s Decoy Virus Revolutionizes Cervical Cancer Prevention

Dr. John T. Schiller

The National Academy of Sciences (NAS), established in 1863, is comprised of the United States’ most distinguished scientific scholars, including nearly 500 Nobel Prize winners. Members of the NAS are elected by their peers and entrusted with the responsibility of providing independent, objective advice on national matters related to science and technology in an effort to advance innovations in the United States.

IRP senior investigator John T. Schiller, Ph.D., was elected to the NAS in 2020 in recognition of a career that has produced numerous discoveries about human papillomaviruses (HPV), sexually transmitted infections that cause genital warts and are responsible for most cases of cervical cancer. His decades-long partnership with fellow IRP senior investigator Douglas R. Lowy, M.D., who was elected to the NAS in 2009, has yielded a deeper understanding of how HPV infects and damages cells and led to the creation of the first vaccines to prevent HPV infection.
