The blood-brain barrier wraps blood vessels where they pass through the central nervous system, controlling the passage of cells and molecules into and out of the brain. The blood-brain barrier becomes disrupted with age, allowing unwanted molecules into the brain, where they can spur chronic inflammation and dysfunction contributing to neurodegeneration. Researchers here investigate the response of astrocytes and microglia, supporting cells of the brain, to the age-related leakage of the blood-brain barrier, in search of points of intervention.
