Dr. Sadhana Jackson — Breaking Through the Blood Brain Barrier
Speaking of Science

2M ago
The blood brain barrier keeps bad actors like toxins, viruses, and bacteria from entering the brain. But in the case of brain cancer when the danger is already inside, the blood brain barrier can work against a person’s health by shutting out the medications meant to eliminate the threat. Dr. Sadhana Jackson from the National Institute of Neurological Disorders and Stroke (NINDS) works to figure out ways to selectively get cancer treatments through the blood brain barrier to treat patients with certain types of brain tumors known as gliomas.

Epidemiologists are the watchful guardians of public health. They collect and analyze data to track the status quo. When there are deviations, they crunch the numbers to understand who is getting sick, where, how, and why. Dr. Meredith Shiels is an epidemiologist and senior investigator at the National Cancer Institute (NCI) studying cancer mortality rates to discern what populations might be at higher risk, figure out ways to mitigate those risks, and evaluate whether those measures are working.   Learn more about Dr. Shiels’s research at  https://irp.nih.gov/pi/meredith-shiels ..read more

10M ago
Despite negative consequences and the desire to stop, millions of people with compulsive behaviors can’t break the self-destructive cycles that disrupt their daily lives. Dr. Veronica Alvarez and Dr. Bruno Averbeck from the National Institute of Mental Health run the Center on Compulsive Behaviors (CCB) which brings together NIH scientists to understand what drives these repetitive and often detrimental behaviors. The CCB strives to decipher the neural circuitry that leads to compulsive behaviors in hopes of improving treatments and designing new interventions. Learn more about the CCB at http ..read more

Sugars, also referred to as carbohydrates, aren’t just substances we add to make coffee taste less bitter or food sweeter; they are an entire class of molecules necessary for life. The study of these carbohydrates is called glycobiology. Dr. John Hanover is a glycobiologist and the chief of the laboratory of cell and molecular biology at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). His work is advancing scientists’ understanding of the sugar structures responsible for rare diseases and genetic transgenerational inheritance ..read more

None of the groundbreaking research taking place in the IRP would be possible with the hard work and dedication of trainees. While they work to support the NIH’s mission to turn discovery into health, the Office of Intramural Training and Education (OITE) works to supports trainees in their professional pursuits. Dr. Sharon Milgram is the director of OITE and a strong proponent that good training begets good science. In this episode, she talks about the many ways OITE supports students and fellows so that they can achieve their best work and make the most of their experience in the IRP ..read more

Dr. Steve Holland — Sussing Out Susceptibility to Sickness
Speaking of Science
by Diego Arenas
1y ago
For Dr. Steve Holland, the mystery of why some people are more prone to disease is as much a curiosity as it is a calling. Dr. Holland is the scientific director and chief of the immunopathogenesis section at the National Institute of Allergy and Infectious Diseases (NIAID) where he searches for signs to explain differences in susceptibility to certain infections. In this episode, he discusses how the immune system can thwart its own defenses by producing antibodies that block the chemical signals it needs to put up a fight ..read more

NASA recently unveiled the first images of the cosmos taken by the James Webb Telescope. But while astronomers point their instruments up to peer into the stars, microscopists like Dr. Hari Shroff are focusing their gaze down to capture life on Earth. As chief of the Section on High Resolution Optical Imaging at the National Institute of Biomedical Imaging and Bioengineering (NIBIB), Dr. Shroff engineers new microscopes to render the invisibly small in new and improved resolution ..read more

Dr. Joyce Chung — Gathering Helping Hands to Grasp Mental Health
Speaking of Science

Finding treatments for mental health conditions doesn't just deal with people who live with them. Healthy volunteers play a critical part in the science of understanding our brains and behavior. But what qualifies as "healthy" can vary across labs and skew how scientists interpret study results. Dr. Joyce Chung, the Deputy Clinical Director at the National Institute of Mental Health (NIMH), is changing that. She is creating a pool of vetted volunteers to bolster the integrity, efficiency, and safety of mental health research ..read more

Dr. Lauren Porter — Molecular “Transformers:” Switching Form and Function
Speaking of Science
by Diego Arenas
2y ago
Science is receptive to new information that can refine the theories we use to make sense of the world. Such is the case with Dr. Lauren Porter, a Stadtman investigator at the National Library of Medicine who is helping redefine the way we understand how proteins behave. She is looking at a new class of proteins that can change their structure and function much like the famous Transformer robots that morph into different machines. Understanding how these proteins switch their shape could help scientists understand the molecular basis of certain diseases like cancer and Alzheimer’s ..read more

Drs. Elaine Ostrander and Heidi Parker — Unleashing the Dog Genome
Speaking of Science
by Diego Arenas
2y ago
Centuries of selective breeding have given rise to a staggering variety of dog breeds, each with its own traits and behaviors. But shallow gene pools have also put some breeds at higher risk for disease. Dr. Elaine Ostrander runs the Dog Genome Project at the National Human Genome Research Institute. Her team includes Dr. Heidi Parker. Together, they are digging for clues to understand how genes code for dogs' diversity and disease. Clues that might also inform the health of their two-legged caregivers ..read more
