Virtual Symposium Showcases Scientists-in-Training
Monday, March 8, 2021
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.
Biomarker Discovery Could Aid Diagnosis and Therapeutic Development
Tuesday, February 16, 2021
Our cells can’t afford to be wasteful, so they prefer to recycle broken components. However, when the mitochondria that provide their energy are damaged beyond repair, cells may have no choice but to throw them out. New IRP research suggests that more of this mitochondrial debris floats in the blood of patients with Alzheimer’s disease, potentially providing an easy, cost-effective way to diagnose or even possibly predict the illness.
First-Trimester Blood Analysis Could Enable Earlier, More Effective Intervention

Imagine a world in which pregnant women routinely travel to places of healing and meet with wise sages who examine a bit of their blood to divine when their babies will be born. While this may sound like something out of Greek mythology, it may soon become a reality, as IRP researchers have developed a test that was able to use blood samples taken early in pregnancy to identify women who would later deliver their babies prematurely.
Experimental Approach Predicts Future Alzheimer’s Diagnoses

If you looked through my garbage, you would probably find a litany of apple cores (my favorite fruit) and a couple fundraising requests from my alma mater. Similarly, scientists can learn a lot about what is going on in cells by examining their trash. IRP researchers recently developed a blood test that may be able to predict Alzheimer’s disease years before the onset of symptoms by examining packages of waste products from neurons.
Annual Event Shares Research by IRP’s Summer Interns
Tuesday, August 13, 2019
NIH’s Natcher Conference Center was packed once again last Thursday for the annual Summer Poster Day. This year, more than 1,200 college and high school students spent their summer performing research in an IRP lab through the NIH’s Summer Internship Program.
I navigated through the more than 900 posters presented this year to get a taste of the impressive work done by these young men and women in less than three months. If they can make these kinds of discoveries in just one summer, imagine what they might one day accomplish as full-time scientists and clinicians!
Five Questions With Dr. Jessica Gill
Wednesday, July 17, 2019
Each year, millions of Americans suffer sports-related concussions, and the number of youth suffering from these traumatic brain injuries has been rising. Blows to the head are common in sports such as football and hockey, and when these forces are strong enough to cause a concussion, they can harm the brain and impair cognitive functioning. Although concussions occur in staggering numbers, scientists do not fully understand what happens to the brain at the time of concussion or during the recovery period. However, that doesn’t mean they’re not trying.
Potential biomarker may contribute to personalized treatments
Tuesday, February 5, 2019
Until recently, medical treatment has largely been one-size-fits-all, with doctors unable to separate patients into distinct groups that might benefit more or less from a particular approach. However, researchers are increasingly finding that individuals with the same disease can differ markedly in ways that might one day influence their care. A recent IRP study has identified a particular molecule that may have just such an impact for patients with damaged lungs.

In 2016, more than one in twenty American adults and one in ten adolescents experienced at least one major depressive episode. For nearly 45,000 of these individuals, their condition was severe enough that it led them to take their own lives. Unfortunately, the medications currently available to treat depression are not always effective and can take up to six weeks to substantially reduce symptoms.
To improve treatment and accelerate symptom relief, IRP senior investigator Carlos Zarate Jr., M.D., is working towards the development of new medications for depression, along with the identification of new drug targets and objective measures called biomarkers that yield information about how a patient is responding to treatment. In recent years, his lab has extensively investigated and assessed the effects of the anesthetic drug ketamine on depression and suicidal thoughts. Many of the patients in his trials have had marked and rapid responses to ketamine, sometimes within a single day or just a couple of hours.
On Tuesday, November 13, Dr. Zarate participated in a Reddit “Ask Me Anything” (AMA) to answer questions from the public about the way depression is currently treated and the latest efforts to develop cutting-edge therapies for the condition. Read on for some of the most interesting exchanges that took place or check out the full AMA on Reddit.

Like a bear leaves its ominous footprints in the snow, diseases and other biological processes often leave traces throughout our bodies. Recent technological and scientific advances have enabled clinicians to use measurements of these ‘biomarkers’ in their attempts to improve our health. A new study by IRP researchers revealed that patients with a sleep disorder called obstructive sleep apnea (OSA) have higher blood concentrations of certain biomarkers that may foreshadow poor brain health later in life.1
When people with OSA sleep, their throat muscles relax and block their windpipes, preventing proper breathing and often waking them up. As a result, these individuals get lower-quality sleep and their brains receive less oxygen at night.
“The overall idea is that those two conditions are not good for brain health, but nobody had really looked to see if some of the biomarkers we see in brain injury are also common in younger individuals with this type of disordered breathing,” says IRP Lasker Clinical Research Scholar Jessica Gill, Ph.D., R.N., the study’s senior author.
