Boosting Brain Activity to Suppress Snacking

Non-Invasive Stimulation Method May Improve Self-Regulation Around Food

Marketers make a living from the fact that merely seeing an advertisement for junk food can spur a sudden craving for potato chips or sugary cereal. Some people have an easier time than others resisting such urges, and over-consuming that sort of food can have problematic consequences for health. Findings from a recent IRP study suggest that stimulating a particular part of the brain might help people who struggle with obesity by enhancing their ability to control their desire to snack.

Overzealous Immune Cells Hamper Healing

Study Points to Treatment Targets for Impaired Healing Due to Diabetes

Whether we’ve nicked a finger while chopping vegetables or wiped out riding a skateboard, we tend to take for granted that our injuries will eventually mend themselves. However, for a type of wound that often plagues patients with diabetes, healing is no sure thing. IRP researchers recently identified why certain immune cells shift from helpful healers into saboteurs in those injuries.

Therapeutic Strategy Protects Heart From Diabetic Damage

Mouse Study Points to Approach for Preventing Diabetes-Related Heart Failure

Our cells love to lap up sugar from our blood, but as is often the case, too much of a good thing can cause problems. In people with diabetes, chronically high blood sugar can harm organs, including the heart. In an effort to combat this life-threatening problem, IRP researchers demonstrated in mice that activating a specific biological pathway in heart cells can reduce diabetes’ damaging effects on the vital organ.

IRP’s Shannon Zenk Elected to the National Academy of Medicine

Nursing Research Leader Sheds Light on How Neighborhoods Influence Health

Dr. Shannon Zenk

When you think about public health, city planning might not be the first thing that comes to mind. Yet where we live — the quality of the buildings, the availability of places to walk and play safely, and the types of schools and stores in the neighborhood — can profoundly affect our health. This relationship has been emphasized by the COVID-19 pandemic, as close, stuffy living conditions, the need to take public transportation to essential jobs, and inequities in access to testing and vaccination sites all contributed to the larger reduction in life expectancy for Black and Latino Americans compared to Caucasians over the last two years.

Shannon N. Zenk, Ph.D., M.P.H., R.N., F.A.A.N., Director of the National Institute of Nursing Research (NINR), was elected to the National Academy of Medicine in 2021 for her research into how neighborhood characteristics affect the health of residents and contribute to the health disparities seen between communities with different racial and ethnic makeups and different levels of income.

Drug Duo Stokes Body’s Fat-Burning Furnace

Mouse Study Suggests Treatment Strategy Could Benefit Patients with Obesity

It’s bad enough that the excess abdominal fat carried by most individuals with obesity causes widespread inflammation throughout their bodies. To add insult to injury, that inflammation actually makes it harder to use up overloaded fat stores. However, a new IRP mouse study supports a two-pronged pharmaceutical approach that could break this vicious cycle and help improve the health of people with obesity.

Duo Delves Into Genetics of Diabetes

Drs. Leslie Baier and Robert Hanson Identify Genetic Risk Factors in American Indians

A team of researchers at NIH’s campus in Phoenix, Arizona, is working with the local American Indian community to learn about genetic risk factors for type 2 diabetes.

November is both Diabetes Awareness Month and Native American Heritage Month. Unfortunately, the month of November is not the only link between Indigenous populations and diabetes. Members of minority groups have a much higher risk of developing type 2 diabetes and its many complications compared to the general population, and this is especially true of some American Indian tribes, whose members are twice as likely to have type 2 diabetes as white Americans.

At the Phoenix Epidemiology and Clinical Research Branch in Arizona, part of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), IRP senior investigators Leslie J. Baier, Ph.D., and Robert Hanson, M.D., M.P.H., are working to understand why American Indians living in the southwestern U.S. are disproportionately affected by type 2 diabetes and obesity. Using family histories, medical records, and other data collected during a decades-long study of these communities, combined with extensive analysis of some of their participants’ DNA, their team has identified several genes that contribute to risk for those two conditions, along with some surprising findings about their prevalence.

IRP’s Charles Rotimi Elected to American Academy of Arts and Sciences

Pioneering Genetic Epidemiologist Takes a Global Approach to Fighting Health Disparities

Dr. Charles Rotimi

IRP distinguished investigator Charles Rotimi, Ph.D., was elected to the American Academy of Arts and Sciences this year in recognition of his pioneering work exploring the health implications of genetic diversity in populations with African ancestry, as well as for globalizing the study of genomics, particularly in African nations. Dr. Rotimi joined NIH in 2008 as the founding director of the Intramural Center for Genomics and Health Disparities in the National Human Genome Research Institute (NHGRI), which was later renamed the Center for Research on Genomics and Global Health, in part to reflect Dr. Rotimi’s globe-spanning research programs.

IRP’s Robert Tycko Elected to National Academy of Sciences

NIH Researcher Recognized for Contributions to Structural Biology Techniques

Dr. Robert Tycko

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 Robert Tycko, Ph.D., was one of two NIH researchers elected to the NAS in 2020, an honor he hopes will give him the opportunity to help other scientists and improve the way science is done.

Introducing NIH’s Newest Lasker Scholars

Program Gives Boost to Early Stage Investigators

Alison Boyce, Ian Myles, Jacqueline Mays, Yogen Kanthi, and Stephanie Chung

If TV shows like The Voice and America’s Got Talent are any indication, there are many extremely talented people out there who could become huge successes if presented with the right opportunity. This is no less the case in science, with thousands of extremely bright individuals quietly toiling away in their mentors’ labs as they await the chance to establish research programs of their own.

Fortunately, initiatives like the NIH’s Lasker Clinical Research Scholars Program exist to boost promising young researchers on to the next stage of their careers. Every year, the Lasker program allows a small group of early stage physician-scientists to establish their own labs at the NIH and carry out independent clinical research there for at least five years.

The five talented investigators selected as 2020 Lasker Scholars are pursuing a wide range of research questions, from how the immune system influences blood clotting to the mechanisms driving a rare and devastating skeletal disorder. Read on to learn more about the latest crop of researchers ramping up IRP labs of their very own.

A Sweet Treatment for Diabetes

Sugar Molecule Protects Mice Against Type 1 Diabetes

Avoiding too much sugar is one of the cardinal rules for those who have or are at risk for diabetes. In fact, diabetes is characterized by having too much glucose, a form of sugar, in the blood. As a result, it came as quite a surprise to IRP researchers led by senior investigator Wanjun Chen, M.D., when they discovered that a particular form of sugar that they expected to have no effect on diabetes-prone mice actually protected them from developing type 1 diabetes.
