Vascular blood–brain barrier. Alternating layers of molecular (glycocalyx, basement membrane) and cellular (endothelial cells, pericytes, astrocytes) components form the blood–brain barrier. The five components are in bold typeface. The basement membrane is a single structure with a two-layer composition, since it is secreted by endothelial cells and astrocytes on either side
