Figure 1.
Schematic of the cross-sectional view of: (a) a peripheral microvessel (the microvessel in non-brain organs), and (b) the blood-brain barrier (BBB) or cerebral microvessel (the microvessel in the brain). In addition to other structures as in a peripheral microvessel, the BBB is wrapped by astrocyte foot processes (AP). BM, Basement membrane (or basal lamina); E, endothelial cell; EN, nucleus of endothelial cell; P, pericytes; G, surface glycocalyx layer; TJ, tight junction. Modified from [40].
