Daily rhythms depend on receptor density in biological clock

mans and other animals, signals from a central circadian clock in the brain generate the seasonal and daily rhythms of life. They help the body to prepare for expected changes in the environment and also optimize when to sleep, eat and do other daily activities. Scientists at Washington University in St. Louis are working out […]

The brain has a waste removal system and scientists are figuring out how it works

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 […]

New technology allows researchers to precisely, flexibly modulate brain

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 […]

Understanding role of T cells in Alzheimer’s disease is aim of new grant

There is increasing evidence that the immune system is involved in the development and progression of Alzheimer’s disease. Most research has focused on the innate immune system and its role in mediating neuroinflammation and degeneration. Naresha Saligrama, PhD, an assistant professor of neurology at Washington University School of Medicine in St. Louis, has received a […]

Gut bacteria boost immune response to fight tumors

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 […]

Some brain tumors may be linked to head injury, mouse study suggests

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 […]

Board grants faculty promotions, tenure

At the Washington University in St. Louis Board of Trustees meeting March 1, numerous faculty members were appointed with tenure, promoted with tenure or granted tenure. Their new roles and titles take effect July 1, unless otherwise indicated. Appointment with tenure Steven Miles as a professor of history in Arts & Sciences. Granting of tenure Paul […]

Focused ultrasound technique gets quality assurance protocol

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 […]

Immunotherapy for Alzheimer’s disease shows promise in mouse study

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 […]

WashU engineers manage a first: measuring pH in cell condensates

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 […]

Neurons help flush waste out of brain during sleep

There lies a paradox in sleep. Its apparent tranquility juxtaposes with the brain’s bustling activity. The night is still, but the brain is far from dormant. During sleep, brain cells produce bursts of electrical pulses that cumulate into rhythmic waves — a sign of heightened brain cell function. But why is the brain active when we […]

Bypassing the blood-brain barrier to improve brain tumor diagnosis

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, […]
