A Cleveland Clinic research team studying alcohol and the brain discovered a new way that alcohol abuse can cause brain dysfunction and damage: through immune cells called microglia. The research also identified a potential new treatment target.

The team showed that in a brain affected by alcohol, microglia tear down the extracellular matrix (ECM), the scaffold that surrounds our neurons. The ECM physically holds our brain cells together and allows them to work properly. When it’s disrupted, our neurons can’t communicate as effectively. Severe ECM disruption can affect our ability to move, think and even remain alert.

The research, published in Immunity, is new, fundamental knowledge that already guides the research team to explore new ways to p...

Scientists at The Wistar Institute have identified a previously overlooked mediator in the body’s response to life-threatening infections: hippuric acid, a metabolite produced when gut bacteria break down polyphenols from berries, tea, and other plant-based foods. The research reveals that this molecule acts as an immune-system amplifier, boosting the body’s inflammatory defenses during early infection but elevating them to deadly levels when infections progress to sepsis.

Published in Cell Reports, the study demonstrates that elevated hippuric acid levels correlate with increased mortality in sepsis patients, while also uncovering the molecular mechanisms by which this metabolite modifies immune re...
