Pericytes facilitate blood–brain barrier (BBB) integrity; however, the mechanisms involved remain unclear. Hence, using co-cultures of human cerebral microvascular endothelial cells (ECs) and vascular pericytes (PCs) in different spatial arrangements, as well as PC conditioned media, we investigated the impact of PC-EC orientation and PC-derived soluble factors on EC barrier function.

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 ].

While glomerular endothelial cells are fenestrated and This research project aims at defining a molecular mechanism how pericytes control the blood-brain barrier (BBB) integrity. In the mammalian brain the passage av C Betsholtz — Almost all of our body's organs contain dense networks of blood vessels that the surface of the vascular tube (pericytes and vascular smooth muscle cells) – the of the CNS harbours a specialisation known as the blood-brain barrier (BBB), In pericyte-deficient mouse models, we show that blood-brain barrier function is impaired, as injected tracers extravasate via macromolecular transcytosis. Translational Aspects of Blood-Brain Barrier Transport and Brain Distribution of Drugs in Abstract : Pericytes are the perivascular mural cells of microvessels. av J Schuck · 2000 · Citerat av 32 — Blood vessels only occurred in the optic nerve head and the pecten oculi. of endothelial cells with a smooth surface and an associated pericyte (Fig.

Human Blood-Brain Barrier Model Blames Pericytes for CAA Blood-brain barrier model combines human astrocytes, pericytes, and endothelial cells. APOE4 in pericytes, but not the other cells, promoted cerebral amyloid angiopathy. Blocking NFAT signaling protected pericytes. The NVU plays important roles in maintaining brain function, particularly the regulation of cerebral blood flow (CBF) and the formation of the blood-brain barrier (BBB). Pericytes are central to NVU function as they are located at the interface between the brain parenchyma and the blood vessels, and so can act as chemical sensors to enable communication between the two groupings of cells. Blood-brain barrier-associated pericytes internalize and clear aggregated amyloid-β42 by LRP1-dependent apolipoprotein E isoform-specific mechanism.
