WebSep 5, 2024 · CD146 coordinates brain endothelial cell-pericyte communication for blood-brain barrier development The blood-brain barrier (BBB) establishes a protective interface between the central neuronal system and peripheral blood circulation and is crucial for homeostasis of the CNS.
WebPericytes wrap around endothelial cells and are located within the basement membrane of capillary and postcapillary blood vessels. Pericytes are also key components of the neurovascular unit including endothelial cells, astrocytes, and neurons and maintain proper blood–brain-barrier (BBB) function in the CNS. How do pericytes regulate angiogenesis? WebMar 9, 2024 · Pericytes, exposed to shear stress, provide adaptive and protective mechanism to endothelial damage by increasing expression of “tissue inhibitor of matrix metalloproteinase 3 (TIMP-3)”, which counter-regulates endothelial ADAMTS-1 and prevents matrix degradation enabling maintenance of vascular stability [ 50 ].
