Study points to new approach to clearing toxic waste from brain (Links to an external site)

An extended form of the protein aquaporin 4 (red) lines the edges of tiny blood vessels in the brain. Cell nuclei are visible in blue. Researchers at Washington University School of Medicine in St. Louis have found a new druggable pathway that enhances the amount of long aquaporin 4 near blood vessels and increases the clearance of waste from the brain. The findings potentially could lead to new therapies to prevent Alzheimer’s dementia.

Researchers at Washington University School of Medicine in St. Louis have found a new druggable pathway that potentially could be used to help prevent Alzheimer’s dementia. Amyloid beta accumulation in the brain is the first step in the development of Alzheimer’s dementia. Scientists have poured countless hours and millions of dollars into finding ways to […]

Modeling personalized medicine for neurocritical illness (Links to an external site)

Precision medicine, which considers the unique characteristics of individuals to provide the most effective treatment, has been a goal of health care providers for decades. Now, it is a goal for helping those with critical neurological illnesses, such as stroke, traumatic brain injury and spine trauma, to track and predict secondary injury, such as seizures, […]

New center’s aim: to ID biomarkers of neurodegenerative diseases (Links to an external site)

Nicolas Barthélemy, PhD, an assistant professor of neurology at Washington University School of Medicine in St. Louis, loads a sample into a mass spectrometer. Barthélemy uses mass spectrometry as part of his work at the university’s new Tracy Family SILQ Center for Neurodegenerative Biology. The center was established to help researchers discover, study and validate biomarkers of neurodegenerative diseases such as Alzheimer’s and Parkinson’s, with a goal of identifying new drug targets and creating better diagnostic and prognostic tests.

A new center established at Washington University School of Medicine in St. Louis aims to accelerate research into biomarkers of neurodegenerative conditions such as Huntington’s and Parkinson’s diseases, amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS) and the so-called tauopathies, a group that includes Alzheimer’s disease along with rarer diseases such as frontotemporal dementia, corticobasal syndrome […]

How St. Louis researchers are seeking ways to combat Alzheimer’s and dementia (Links to an external site)

Alzheimer’s disease starts forming in the brains of unsuspecting individuals about 20 years before traditional telltale signs become noticeable. No cure exists for the progressive, fatal disease, but St. Louis medical researchers are studying tools and potential drugs that can detect and treat Alzheimer’s in its early stages. “The tests are getting better and better,” […]

Calming overexcited neurons may protect brain after stroke (Links to an external site)

By scanning the genomes of nearly 6,000 stroke patients, researchers at Washington University School of Medicine in St. Louis identified two genes associated with recovery. Both are involved in regulating neuronal excitability, suggesting that targeting overstimulated neurons may help promote recovery in the pivotal first 24 hours.

A new study has prompted scientists to reconsider a once-popular yet controversial idea in stroke research. Neuroscientists believed that, in the aftermath of a stroke, calming overexcited neurons might prevent them from releasing a toxic molecule that can kill neurons already damaged by lack of oxygen. This idea was supported by studies in cells and […]

Poverty, crime linked to differences in newborns’ brains (Links to an external site)

Scanning the brains of newborns, researchers at Washington University School of Medicine in St. Louis have found that maternal exposure to poverty and crime can influence the structure and function of young brains even before babies make their entrances into the world. Here, the university's Lourdes Bernardez prepares an infant for an MRI scan as part of ongoing research.
