Blood-brain barrier
Topic: Anatomy & physiology
A selective barrier, formed by tight junctions between brain capillary endothelial cells, that limits the passage of many substances from blood into brain tissue. It protects the brain from toxins and pathogens but also keeps many drugs out of the central nervous system. In newborns, very high bilirubin levels can cause kernicterus, a form of brain damage.
- Also known as:
