Experimental Treatment Helps Neurons Recover From Damage

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

Tuesday, September 12, 2023

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.

Taming Unruly Stem Cells to Enhance Eye Research

Widely Available Molecule Could Aid Development of Therapies for Blinding Diseases

Tuesday, October 4, 2022

eye

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.

Postdoc Profile: A Bird’s-Eye View of Retinal Disease

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

Monday, April 11, 2022

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.

Newly Discovered Mutation Causes Eye Disease

Tuesday, September 25, 2018

The Human Genome Project gave scientists an incredible roadmap of the thousands of genes used to construct the human body. However, many individuals harbor DNA that differs markedly from the standard reference sequence produced by that initiative, and these variations can have profound implications for a person’s health. A recent study led by IRP scientists has uncovered yet another of these genetic variants, a rare mutation that causes the eye disease retinitis pigmentosa.

IRP Interns Shine at Summer Poster Day

NIH summer intern Ishu Sivakumar at Summer Poster Day

Upon entering the sunny foyer of the NIH’s Natcher Conference Center last Thursday, I was immediately struck by a burst of loud, excited chatter. As it always is on NIH’s annual Summer Poster Day, the building was filled with hundreds of high school and college students and the scientists, families, and friends who had turned out to see what these young men and women had spent the summer doing.

Developing Methods to Study the Brain's Visual System in Action

Friday, January 6, 2017

How does the brain know that what we’re looking at is standing still or moving? Dr. Robert H. Wurtz developed methods for studying the visual system, a technique now widely used for the study of higher brain functions, to find the answer to that question.

Early Women Scientists of NIH, Part 1

A Elizabeth Verder

This month we’ll be looking at lesser-known early women scientists at the National Institutes of Health. They did solid work and were leaders in their field, but for some reason, they aren’t well-known.
