2015-04-17 Pericyte, Astrocyte and Basal Lamina Association with the Blood Brain Barrier (BBB) The periendothelial accessory structures of the BBB include pericytes, astrocytes, and a basal membrane. The endothelial cells of the BBB are distributed along the length of the vessel and completely encircles the lumen. 2016-03-01 Pericytes include a population of cells surrounding capillaries that signal directly to the underlying endothelial cells and form a permeability barrier. Pericytes also play critical roles in hemostasis, maintenance of the blood–brain barrier, angiogenesis, and neovascularization.

It has been found that pericytes are crucial to the postnatal formation of this barrier. The blood–brain barrier is formed by endothelial cells of the capillary wall, astrocyte end-feet ensheathing the capillary, and pericytes embedded in the capillary basement membrane.

When the BBB malfunctions, it may lead to diabetes, multiple sclerosis, or Alzheimer’s disease. The blood–brain barrier (BBB), consisting of specialized endothelial cells surrounded by astrocytes and pericytes, plays a crucial role in brain homeostasis. Many cerebrovascular diseases are associated with BBB breakdown and oxygen (O 2) deprivation constitutes a critical factor that onsets its disruption. 2020-01-11 · Pericytes are partially sandwiched between endothelial cells and astrocyte end feet and represent important constituents of the neurovascular unit, and they have traditionally been considered essential for normal blood–brain barrier function [ 3 ]. 2021-03-31 · The blood-brain barrier protects the brain and maintains homeostasis. Dysfunction of the blood-brain barrier is linked with neurological conditions.

2020-06-29 2010-11-01 2017-05-24 Cerebral pericytes constitute an essential component of the blood‐brain barrier (BBB) and are involved in blood vessel assembly. Recently, we reported on the induction of a BBB‐specific enzyme expressed by cerebral pericytes (pericytic aminopeptidase N/pAPN) in coculture with cerebral endothelial cells. Cerebral pericytes constitute an essential component of the blood‐brain barrier (BBB) and are involved in blood vessel assembly.
