Historically, people with amyotrophic lateral sclerosis (ALS) experience a relentless decline of neurological function that eventually robs them of the ability to move, speak, eat or breathe. Now, researchers from Washington University School of Medicine in St. Louis and collaborators report that long-term use of tofersen, a new drug approved by the Food and Drug […]

Nature is often the best model for science. For nearly a century, scientists have been trying to recreate the ability of some mammals and birds to survive extreme environmental conditions for brief or extended periods by going into torpor, when their body temperature and metabolic rate drop, allowing them to preserve energy and heat. Taking […]

Mouse study shows engineered immune cell therapy protects damaged neurons
With new technique, patient-derived neurons accurately model late-onset Alzheimer’s, point to potential treatments
The brain needs to flush out waste products to stay healthy and fend off conditions like Alzheimer’s disease. Scientists are beginning to understand how the the brain’s waste removal system works. [Transcript] A MARTÍNEZ, HOST: Turns out the brain needs regular cleaning. Otherwise, it gets clogged up with waste products, including some associated with diseases […]
Human brain diseases, such as Parkinson’s disease, involve damage in more than one region of the brain, requiring technology that could precisely and flexibly address all affected regions simultaneously. Researchers at Washington University in St. Louis have developed a noninvasive technology combining a holographic acoustic device with genetic engineering that allows them to precisely target […]
The one-year awards promote collaborative research within the university
A study in mice by researchers at the School of Medicine indicates that brain injury can lead to brain tumors in susceptible individuals. For this study, they used mice that model people with neurofibromatosis type 1 (NF1), a genetic disorder that causes brain tumors. The study showed that molecules released by injured neurons set off […]
For the past several years, Washington University in St. Louis researchers have been using focused ultrasound combined with microbubbles to target an opening in the tough, protective blood-brain barrier to deliver drugs or retrieve biomarkers. To ensure that the fast-developing technology functions safely and consistently, Hong Chen, PhD, and her team, including first author and […]
Popular alternative to CPAP machines may not be appropriate for all
Hong Chen, Jon Silva, both in biomedical engineering, are honored as rising leaders in their fields
First-in-human trial demonstrates safety of sonobiopsy in patients with glioma Getting a biopsy is often an important first step for cancer diagnosis and treatment. But brain tumors present unique challenges: to perform a biopsy, a neurosurgeon will likely need to drill into the skull, and removing brain tissue can cause complications, including bleeding, brain swelling, […]

Sonobiopsies generate genetic, molecular data to inform treatment decisions for brain diseases
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 […]
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 […]
Grant will support research on brain plasticity
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 […]
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 […]
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 […]
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., […]
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 […]
