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
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, […]
FDA grants WashU-based technology ‘Breakthrough Device’ designation
Sarah D. Ackerman, PhD, Gabor Egervari, MD, PhD and Tao Xie, PhD, all of Washington University School of Medicine in St. Louis, have been named 2023 Young Investigator grantees by the Brain & Behavior Research Foundation. This year’s funding will support 150 promising early-career scientists across the field of neuropsychiatry with innovative ideas in mental health research. The two-year grant […]

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 […]
Honored for work developing new kind of therapy for neurodegenerative diseases
New imaging technique reveals circulation patterns in developing brain
Research could facilitate diagnosis of Alzheimer’s disease
“These trials don’t go without huge input and commitment from the participants and of course, their caregivers, and the clinical trial sites. I have the privilege of speaking to you about the trial as the lead author of this paper, but this is a team effort and includes a large group of people from multiple […]

Hong Chen’s lab develops technique to generate Airy beams for ultrasound focusing
A submarine can inadvertently reveal its location because of cavitation, a condition that creates bubbles underwater that burst, then emit sound waves that can be detected by sonar. A team of biomedical engineers at Washington University in St. Louis plans to use the same concept to detect cavitation in human brains that may contribute to […]

Research to explore the effects of social isolation on cognitive, emotional health
Hong Chen, medical school faculty to collaborate on NIH-funded work
When a patient is informed of a brain tumor, the experience is frightening. “When anyone finds out they have a brain tumor. It is super scary,” described neurosurgeon and scientist Dr. Albert Kim, MD, PhD, the inaugural director of the new Brain Tumor Center at Siteman Cancer Center at Barnes Jewish Hospital and Washington University […]
Finding prompts researchers, clinicians to consider impact in future research, clinical treatment of brain diseases
At the Washington University in St. Louis Board of Trustees meeting May 7, numerous faculty members were appointed or promoted with tenure or granted tenure, effective July 1 unless otherwise indicated. Promotion with tenure Megan Tierney Baldridge, MD, PhD, to associate professor of medicine at the School of Medicine; Trevor G. Gardner II to professor of […]
