Pericyte physiology
WebAug 1, 1993 · This review focuses principally on nonmesangial pericytes and specific activities such as the posttranslational, short‐term responses that affect microvascular perfusion and permeability, and on pericyte‐endothelial cell interaction. Endothelial cells are the primary physical barrier between blood and tissue in microvessels. The other capillary … WebPericytes are centrally positioned within the neurovascular unit, contain contractile proteins, and respond rapidly to neuronal stimulation ( 18, 19 ). Despite their critical role, pericytes have been understudied in the context of neurodegenerative diseases.
