blood-brain barrier ['blʌdbreɪn'bærɪə]
med.	A semi-permeable layer of tightly joined cells that separate the brain from circulating blood. The blood-brain barrier prevents potentially dangerous substances in the blood, such as disease-causing organisms or chemical compounds, from entering the brain tissue. Certain antiretroviral ARV drugs can cross the blood-brain barrier and may help stop or slow HIV damage to the brain.
