Clinical trial for RVCL-S patients tests drug already approved as sickle cell disease treatment
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 […]
Morby prize from Cure Alzheimer’s Fund honors discovery of T cells’ role in neurodegeneration
Roughly one in five cancer patients benefits from immunotherapy – a treatment that harnesses the immune system to fight cancer. Such an approach to beating cancer has seen significant success in lung cancer and melanoma, among others. Optimistic about its potential, researchers are exploring strategies to improve immunotherapy for cancers that don’t respond well to […]
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 […]

Perlmutter, MD, executive vice chancellor for medical affairs, the George and Carol […]
Study highlights need to develop therapies for this vulnerable population
Alzheimer’s disease starts with a sticky protein called amyloid beta that builds up into plaques in the brain, setting off a chain of events that results in brain atrophy and cognitive decline. The new generation of Alzheimer’s drugs — the first proven to change the course of the disease — work by tagging amyloid for […]
Scientists trying to understand the physical and chemical properties that govern biomolecular condensates now have a crucial way to measure pH and other emergent properties of these enigmatic, albeit important cellular compartments. Condensates are communities of proteins and nucleic acids. They lack a membrane and come together and fall apart as needed. The nucleolus is […]

Rohit V. Pappu, PhD, an internationally renowned researcher in biomolecular condensates and intrinsically disordered proteins, was installed Oct. 9 as the Gene K. Beare Distinguished Professor of Biomedical Engineering at Washington University in St. Louis. Pappu is a professor of biomedical engineering and director of the Center for Biomolecular Condensates at the McKelvey School of […]
Song Hu plans to develop deep-brain fiber-optic techniques to investigate the cause of memory loss in Alzheimer’s disease
Membership is one of highest U.S. honors in health and medicine
Key steps leading to such accumulation identified; could inform new therapeutic approaches
This episode of ‘Show Me the Science’ focuses on approval of a drug that attacks a key protein that contributes to dementia from Alzheimer’s disease
Test results available in less than a minute
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 […]
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 […]
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 […]
Accurate diagnosis is a crucial step toward appropriate treatment
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, […]
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 […]
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 […]
