01
Overview
Blood-brain barrier (BBB) stabilization refers to the maintenance or restoration of the structural and functional integrity of the BBB, a highly selective semipermeable border that separates circulating blood from the brain's extracellular fluid. It involves complex cellular interactions primarily among endothelial cells, pericytes, astrocytes, and regulation through specific molecular pathways including tight junction proteins and growth factors like osteopontin/VEGF/angiopoietins that together preserve CNS homeostasis under physiological conditions while limiting pathological leakage during disease states.
