The blood–brain barrier (BBB) is a dynamic interface that tightly regulates the transport of substances from the blood into the brain. BBB dysfunction can occur with ageing and is a hallmark of many major diseases but is underappreciated as a therapeutic target. Here, Searson and Banks review studies on BBB repair and rejuvenation, highlighting common mechanisms across disorders and potential strategies for pharmacological intervention.
