The vast array of pericyte functions include contractility, immunologic, migratory, and angiogenic. Pericytes have stem cell potential, contribute to the integrity of the blood-brain barrier, and have a regulatory role for hemostasis in the brain.

Pericytes undergo several morphological and phenotypic changes in stroke. Pericytes are vital to many very important brain functions and have very elaborate signaling with capillary cells, astrocytes, neurons and other glia. The details are just now emerging. Very important functions of this signaling includes all passage of cells and materials at the blood brain barriers and blood flow to specific neuronal regions.

U., Dehouck, M. P., Cecchelli, R. Blood-brain barrier pericytes are the proteins influence brain capillary endothelial barrier function in vitro.

Pericytes are crucial participants in the physiological and pathological processes of cardiovascular disease. They actively interact with endothelial cells, vascular smooth muscle cells (VSMCs), fibroblasts, and other cells via the Pericytes and vSMCs line the outer walls of blood vessels and play critical roles in blood vessel and endothelial cell function. Interestingly, despite the recent interest in the role of blood vessels in insulin secretion and insulin action, a role for pericytes in these processes has not been well described. This video “Pericyte: Definition, Structure & Function” is part of the Lecturio course “Histology” WATCH the complete course on http://lectur.io/pericytes T1 - Functions of Pericytes in Ischemic Stroke.

The contractile function in pericytes was also highlighted by the identification of contractile proteins such as tropomyosin and myosin. Furthermore, pericytes express both cholinergic and adrenergic receptors (α-2 and β-2). Specifically, α-2 response leads to contraction, whereas β-2 stimulation causes pericyte relaxation .

Pericytes: Purpose and Function / January 31, 2021 . Pericytes are cells that wrap around endothelial cells throughout the body. They are essential for the regulation of blood flow and maintenance of homeostasis within the body, such as the blood-brain barrier.

Pericytes also play important roles in regulating capillary blood flow, in angiogenesis, in hematopoiesis, in maintaining the permeability of the blood-brain barrier, in wound healing, and in leukocyte trafficking (Armulik et al., 2011). Definition of pericytes – a heterogeneous population of stem cells Pericytes are uniquely positioned at the blood-brain interface. These cells maintain vascular function. Microvascular changes often involve pathological pericyte activation and bloodbrain barrier dysfunction.

2020-10-15 · Pericytes play essential roles in blood–brain barrier (BBB) integrity and dysfunction or degeneration of pericytes is implicated in a set of neurological disorders although the underlying mechanism Se hela listan på frontiersin.org Pericytes, perivascular cells lining capillaries, have increasingly gained interest as a novel target cell type. This is due to their multiple functions after stroke that include maintenance of the BBB and their participation in vascular remodeling and scar formation. Pericytes undergo several morphological and phenotypic changes in stroke. One of the main functions of pericytes is the control of vessel diameter and cerebral blood flow in response to neuronal activity, implemented by the high abundance of α-smooth-muscle actin in this particular cell type (Peppiatt et al., 2006).

Pericytes are attracting increasing attention as important regulators during development and during normal and disturbed organ function. In recent years 

Skeletal muscle and cardiac pericytes are now recognised to fulfil an increasing number of functions in normal tissue homeostasis including contributing to microvascular function by maintaining vessel stability and regulating capillary flow. Pericytes: Purpose and Function / January 31, 2021 . Pericytes are cells that wrap around endothelial cells throughout the body. They are essential for the regulation of blood flow and maintenance of homeostasis within the body, such as the blood-brain barrier. Researchers at the Center for Vascular Research, within the Institute for Basic Science (IBS) are studying the role of cells called pericytes, which protectively wrap the retinal vessels building Title:The Role of Pericytes in Blood-Brain Barrier Function and Stroke VOLUME: 18 ISSUE: 25 Author(s):Shuo Liu, Dritan Agalliu, Chuanhui Yu and Mark Fisher Affiliation:UC Irvine Medical Center, 101 The City Drive South, Shanbrom Hall Room 121, Orange, CA 92868.
