IRP’s Michael Chiang Elected to National Academy of Medicine

NEI Director is Envisioning the Future of Eye Research

Dr. Michael Chiang

Vision is one of the most important ways we experience the world around us, so naturally, when disease and injury threaten sight, the impact of that loss can cause significant harm to our quality of life. That’s why, when Michael F. Chiang, M.D., became director of NIH’s National Eye Institute (NEI), he felt it was so important to incorporate this sentiment into his Institute’s new mission statement: “To eliminate vision loss and improve quality of life through vision research.”

This past fall, Dr. Chiang was elected to the National Academy of Medicine (NAM) for his own contributions to that mission, through his research on eye disease and the use of data and technology to improve treatment and access to vision care. His work has particularly focused on the diagnosis and treatment of retinopathy of prematurity (ROP), a complication that can lead to blindness among premature and low-birthweight babies.

Experimental Treatment Helps Neurons Recover From Damage

Mouse Study Could Lead to New Therapies for a Variety of Ailments

neurons firing

In most parts of your brain, the set of neurons you’re born with is what you’ve got for life — just like your fingers and toes, if you lose any, they’re not coming back. The body does have ways to encourage healing after a brain injury, but they are extremely constrained. However, by lending those natural systems a helping hand, IRP researchers have managed to dramatically boost regeneration and recovery of vision in mice with damage to the nerves that connect the eyes to the brain, an approach that could one day help people recover from other types of nervous system injuries as well.

Scouting Out Summer Poster Day

Annual Event Held In-Person for First Time in Four Years

A few weeks ago, NIH’s Natcher Conference Center bustled with the youthful scientific enthusiasm of IRP summer interns for the first time since 2019, the last time that the IRP’s Summer Poster Day was held in-person. At this year’s event, held on August 3 and 4, the hundreds of high school and college students who conducted research in IRP labs as part of NIH’s Summer Internship Program this year eagerly showed off the fruits of their labors — from discoveries about how weight loss drugs affect the brain to new insights into a potential treatment target for age-related vision loss. Read on to learn more about a few of these scientific upstarts and the research revelations they’ve helped uncover.

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.

Taming Unruly Stem Cells to Enhance Eye Research

Widely Available Molecule Could Aid Development of Therapies for Blinding Diseases

As scientists inch closer to growing fully functioning organs outside the body, it’s easy to forget that it’s already possible to grow miniature, simplified versions of some organs in the lab. These ‘organoids’ are an extremely useful research tool, but producing them can be tricky. New IRP research could make it much easier to grow organoids that mimic the eye’s retina, thereby accelerating discoveries about a variety of vision-impairing diseases.

Dr. Noor White Traces Evolution to Identify Genes Critical for Vision

Dr. Noor White

The eye has existed in some form for roughly 600 million years. Its many intricate components and the general ability of organisms to sense light have continued to adapt and evolve over huge spans of time into what we know as vision today. By mapping out the evolution of vision, Noor White, Ph.D., hopes to shed light on the genetic causes of diseases that affect the retina, the part of the eye that turns light into electrical signals the brain can use to build an image of our surroundings.

“If we can take a step back and look at the bigger picture, then we can identify the critical genetic components of vision,” explains Dr. White, who was an IRP postdoctoral fellow for four years before becoming a Staff Scientist in March.
