Scientists are beginning to understand how long COVID symptoms affect the brain

Many symptoms of long COVID are related to the brain. Now scientists are beginning to understand why brain fog, fatigue, and pain can linger for years after a person was infected. ARI SHAPIRO, HOST: Months or even years after getting COVID-19, some people still have neurological symptoms like pain, fatigue and brain fog. MICHELLE WILSON: […]

Yi and Gabel receive grants to study autism-related disorders

Jason Yi, PhD, an assistant professor of neuroscience, and Harrison Gabel, PhD, an associate professor of neuroscience, both at Washington University School of Medicine in St. Louis, each have received two-year $300,000 pilot grants from the Simons Foundation Autism Research Initiative. The researchers will use the funds to investigate genetic diseases that result in autism. […]

Cognitive function in Down syndrome-associated Alzheimer’s focus of grant

Nearly every person with Down syndrome eventually develops Alzheimer’s disease, yet people with the syndrome routinely are excluded from Alzheimer’s clinical trials, as the cognitive assessment tools designed for the general population often are inappropriate for people with developmental disabilities. Consequently, nobody knows whether the new Alzheimer’s therapeutics hitting the market will work for people […]

New Technique for Diagnosing Brain Diseases is Successfully Put to the Test

Hong Chen, PhD, associate professor of biomedical engineering and radiation oncology at Washington University in St. Louis, is dedicated to what may seem like the impossible. “This constant puzzle of what’s happening in my brain.” Chen is referring to all human brains that share this complexity. And getting answers to serious problems can be very […]

Brain movement measured for clues to prevent, reduce injury

When the human head experiences any kind of movement — from nodding yes or no to heading a soccer ball or being jolted in a car crash — the brain moves inside the skull, leading to deformation of the tissue. Such deformations are key to understanding traumatic brain injury but are challenging to study since […]

NIH funds study of ultrasound with genetics to treat brain disorders

Researchers have developed methods to study and manipulate areas of the brain, though many of those methods are restricted by the limited depth that light can reach within the brain. A multidisciplinary team at Washington University in St. Louis plans to overcome that limitation by integrating ultrasound with genetics to precisely modify neurons in the […]

Tau-based biomarker tracks Alzheimer’s progression

Two pathologies drive the progression of Alzheimer’s disease. Early on, amyloid beta plaques lead the way, but around the time cognitive symptoms arise, tau tangles take over as the driving force and cognition steadily declines. Tracking the course of the disease in individual patients has been challenging because there’s been no easy way to measure […]

Air monitor can detect COVID-19 virus variants in about 5 minutes

Now that the emergency phase of the COVID-19 pandemic has ended, scientists are looking at ways to surveil indoor environments in real time for viruses. By combining recent advances in aerosol sampling technology and an ultrasensitive biosensing technique, researchers at Washington University in St. Louis have created a real-time monitor that can detect any of […]

The evolution of Ephraim Oyetunji

Ephraim Oyetunji likes a good challenge. “Everything is a mystery to be solved,” he said. A senior biology major on the neuroscience track, Oyetunji quickly established himself as a standout researcher. He’s been named a WUSTL ENDURE scholar, a Hope Center Scholar, and a recipient of the prestigious Barry Goldwater Scholarship. Oyetunji discussed his path […]

Altered gut bacteria may be early sign of Alzheimer’s disease

People in the earliest stage of Alzheimer’s disease — after brain changes have begun but before cognitive symptoms become apparent — harbor an assortment of bacteria in their intestines that differs from the gut bacteria of healthy people, according to a study by researchers at Washington University School of Medicine in St. Louis. The findings, […]

Gordon wins Spain’s Asturias Award

Microbiome pioneer Jeffrey I. Gordon, MD, of Washington University School of Medicine in St. Louis, has won the 2023 Princess of Asturias Award for Technical and Scientific Research. The Asturias awards, among the most prestigious honors in the Spanish-speaking world, are presented annually in eight categories. The awards are designed to recognize exceptional scientific, technical, cultural, […]

Induction of a torpor-like state with ultrasound

Some mammals and birds have a clever way to preserve energy and heat by going into torpor, during which their body temperature and metabolic rate drop to allow them to survive potentially fatal conditions in the environment, such as extreme cold or lack of food. While a similar condition was proposed for scientists making flights […]

Findings may lead to improved insulin-secreting cells derived from stem cells

Diabetes researchers at Washington University School of Medicine in St. Louis have uncovered at least one reason insulin-secreting cells made from stem cells in the lab don’t work as well as natural cells. The discovery could help speed progress toward making insulin-secreting cells — called islet beta cells — more effective in the treatment of […]

Bagnall wins grant to map neuronal connections

Martha Bagnall, PhD, an assistant professor of neuroscience at Washington University School of Medicine in St. Louis, received a $1.9 million R01 grant from the National Institute of Neurological Disorders and Stroke, part of the National Institutes of Health (NIH), to map neuronal connections in the zebrafish spinal cord. The Bagnall lab studies motor control […]

Insight into brain’s waste clearing system may shed light on brain diseases

Like the lymphatic system in the body, the glymphatic system in the brain clears metabolic waste and distributes nutrients and other important compounds. Impairments in this system may contribute to brain diseases, such as neurodegenerative diseases and stroke. A team of researchers in the McKelvey School of Engineering at Washington University in St. Louis has […]

Pappu to explore ways in which charge contributes to diverse states of proteins

Intrinsically disordered proteins (IDPs) are defined by structural diversity, and the determinants of this diversity are an important area of biophysical investigation. IDPs are involved in a range of important biological processes, including cell signaling and regulation, that allow healthy cells to respond to environmental factors appropriately, but they are also associated with human diseases […]

Paul Taghert awarded $1.9 million Outstanding Investigator Award

The National Institutes of General Medical Sciences has awarded an Outstanding Investigator Award of nearly $2 million to Paul Taghert, PhD, Professor of Neuroscience at Washington University School of Medicine, to study how the circadian clock orchestrates multiple biological cycles that operate at different phases. Physiological and behavioral rhythms, such as sleep, hormone fluxes, and eating, […]

Gabel Lab identifies molecular links between Sotos and Tatton Brown Rahman Syndromes

Sotos Syndrome and Tatton Brown Rahman Syndrome bear striking similarities, so much so that patients with one have been misdiagnosed as having the other. Both rare diseases cause large stature and head size, also known as overgrowth, distinct facial features, a high prevelance of autism, and intellectual disability. But the two diseases have different genetic […]

Drug for rare form of ALS, based in part on WashU research, approved by FDA

A new drug has been approved by the Food and Drug Administration (FDA) for a rare, inherited form of amyotrophic lateral sclerosis (ALS), a paralyzing neurological disease. Known as tofersen, the drug has been shown to slow progression of the deadly disease. International clinical trials of tofersen, developed by the global biotechnology company Biogen Inc., […]

Adding med to antidepressant may help older adults with treatment-resistant depression

For older adults with clinical depression that has not responded to standard treatments, adding the drug aripiprazole (brand name Abilify) to an antidepressant they’re already taking is more effective than switching from one antidepressant to another, according to a new multicenter study led by Washington University School of Medicine in St. Louis. Aripiprazole originally was […]
