NIH Scientist Proves What Happens in the Mouth Doesn’t Stay in the Mouth

Dr. Jennifer Webster-Cyriaque

For many people, good oral health means a pretty smile, not necessarily a healthy body. However, poor dental health can lead to serious illness and disability. IRP senior investigator Jennifer Webster-Cyriaque, D.D.S., Ph.D., has spent her career illuminating the connection between our mouths and our overall health. Dr. Webster-Cyriaque, who recently joined NIH as Deputy Director of the National Institute of Dental and Craniofacial Research (NIDCR) and Chief of the Viral Oral Infections in Immunosuppression and Cancer Laboratory at the National Institute of Allergy and Infectious Diseases (NIAID), was elected to the National Academy of Medicine in October for her seminal contributions to our understanding of viruses that infect the mouth.

Poster Session Showcases IRP Graduate Students

Event Includes In-Person Presentations for First Time Since 2020

Three years after COVID-19 dramatically changed the way scientists and many others work, much of life in the NIH IRP has begun to resemble the way things were in February of 2020. This includes the return of in-person scientific poster sessions like the one that took place on February 16 as part of the 19th annual NIH Graduate Student Research Symposium. Nearly 130 graduate students conducting their Ph.D. research in IRP labs as part of NIH’s Graduate Partnership Program presented their progress at that poster session and its virtual counterpart held February 15.

The two poster sessions made it clear that IRP graduate students are essential contributors to the life-changing discoveries made at NIH, from using geckos to learn about human eye diseases to investigating how the immune system combats infectious invaders to exploring ways to improve cancer treatment. Keep reading to learn about some of the bright scientists-in-training who showed off their work during the two-day event.

IRP’s Eugene Koonin Elected to National Academy of Medicine

Scientist Decoded DNA to Build a Genomic Tree of Life

Dr. Eugene Koonin

In 1973, the geneticist Theodosius Dobzhansky wrote a now-famous essay that declared, “Nothing in biology makes sense except in the light of evolution.” That sentiment has served as the guiding principle for the career of IRP senior investigator Eugene V. Koonin, Ph.D., who was elected to the National Academy of Medicine (NAM) in October 2022 for his contributions to the field of evolutionary biology.

Dr. Koonin’s pioneering efforts to identify clusters of similar genes found in different organisms passed down by a common ancestor — known as ‘homologous’ genes — has helped to unlock the secrets encoded in DNA and create a foundation for the systematic study of how genes evolve and function. His lab at the National Library of Medicine’s National Center for Biotechnology Information (NCBI) uses a combination of genomic sequencing and mathematical modeling to compare genes across species and determine how they work and where they came from. From this information, his team can develop a systematic framework to show the relationship between genes as they evolved. It’s like drawing the tree of life, but on a genomic scale.

Friendly Virus Could Deliver Gene Therapy Under Immune System’s Radar

IRP Research Points to New Tool for Alleviating Genetic Disorders

With all the dangerous viruses out there, from the seasonal flu to the novel coronavirus that causes COVID-19, people understandably want to make sure their immune systems are topped-up with disease-fighting antibodies that block viral invaders. However, when it comes to the viruses scientists are modifying to deliver gene therapy, having a robust immune response is actually an obstacle to getting healthy. In a new study, IRP researchers showed that most people’s immune systems don’t react to a particular harmless virus that can effectively deliver new genes to the liver and heart, making it a promising delivery vehicle for therapies designed to alleviate a life-threatening genetic condition.

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.

Global Scientists Come Together at the National Institutes of Health

Individuals From Around the World Drive IRP Breakthroughs

Dr. Flossie Wong-Staal

Come to NIH and you’ll hear many accents. Scientists from around the world have always contributed significantly to the NIH mission. The resulting diversity of backgrounds and perspectives makes the NIH Intramural Research Program an extremely stimulating and productive environment. Read on to learn about some of the many scientists of the past and present who brought their talents from abroad to one of the world’s leading institutions for biomedical research.

Mold Exposure Sets Stage for Severe Flu

Mouse Study Suggests Common Fungus Could Worsen Respiratory Infections

Throughout the COVID-19 pandemic, both scientists and the media have focused on the factors that influence who experiences mild symptoms or none at all and who faces potentially life-threatening consequences from the disease. Other respiratory viruses like the flu also have widely varying effects on different patients. New IRP research has found that exposure to a common variety of mold primes the immune system to overreact to the flu virus, dramatically increasing the illness’s severity.

A Multi-Front Effort to Combat Coronavirus

IRP Research Examines Pandemic From All Angles

The sheer number of labs and wide variety of scientific perspectives in the IRP make it particularly well-suited to combating a disease like COVID-19, which is affecting patients’ health and the world around them in a huge number of ways. IRP researchers specializing in psychology, genetics, epidemiology, and many other disciplines are pursuing an array of strategies to learn more about the novel coronavirus.

Pandemic Brings All Hands on Deck

IRP Investigators Begin Hundreds of New Coronavirus-Related Studies

Within just a few months after COVID-19 began spreading in the United States, IRP researchers had already made numerous important contributions to the fight against the deadly virus. Scientific knowledge about the disease continues to expand at a unprecedented pace, and the IRP will continue to play a major role in this effort over the coming months and years. In fact, nearly 300 new intramural research projects related to the novel coronavirus are currently starting up or have already begun.

IRP’s Michael Lenardo Elected to National Academy of Sciences

NIH Researcher Recognized for Enhancing the Molecular Understanding of Immune Responses

Dr. Michael Lenardo

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 Michael Lenardo, M.D., is one of four IRP researchers elected to the NAS over the past two years. At the NIH, Dr. Lenardo serves as Chief of the Molecular Development of the Immune System Section at the NIH’s National Institute of Allergy and Infectious Diseases (NIAID), where he studies how the cells in the immune system mount protective responses to various pathogens, including viruses and bacteria. A major focus of Dr. Lenardo’s work is the investigation of genetic abnormalities in the immune system, which have the potential to cause life-threatening diseases.
