Pericytes are contractile cells that wrap around the endothelial cells of capillary and venules throughout the body. Pericytes are embedded in basement membrane
Unique slender cells with multiple processes extending along the capillary vessel axis and encircling the vascular wall, also called mural cells. Pericytes are imbedded in the BASEMENT MEMBRANE shared with the ENDOTHELIAL CELLS of the vessel. 2019-04-02 2020-05-01 2021-02-18 Pericytes are an integral part of the crosstalk among cells in the perivascular space. They interact not only with endothelial cells, but also with hematopoietic cells and immune cells, and are considered regulators of angiogenesis. per·i·cyte. ( per'i-sīt) One of the slender mesenchymallike cells found in close association with the outside wall of postcapillary venules; it is relatively undifferentiated and may become a fibroblast, macrophage, or smooth muscle cell. Synonym (s): adventitial cell.

with the recruitment of perivascular mural cells (smooth muscle cells, pericytes). The group studies the essential role of Angiopoietin/Tie signaling in blood and Most of the current research focuses on the role of endothelial cells, however endothelial cell physiology is strongly related to pericyte function. It is unclear to what degree perivascular fibroblasts and pericytes generate ATP from glycolysis or oxidative phosphorylation (OXPHOS), which Targeting pericyte-mediated immunosuppression in Glioblastoma multiforme.

9.1 and 9.2). Pericytes cover between 22% and 99% of the endothelial cell surface.
Blod-hjärnbarriären är mycket tätt sammanfogade kapillärväggar i hjärnans blodkärl som skyddar hjärnvävnaden. Blod-hjärnbarriären hindrar vissa droger, läkemedel och celler (till exempel vita blodkroppar, mikroorganismer) från att lämna blodbanan och nå hjärnans nervceller.
In the central nervous system (CNS), pericytes are necessary for the formation and regulation of the blood-brain barrier (BBB) and pericyte deficiency accompanies CNS diseases including multiple sclerosis, diabetic Pericytes, along with neurons, astrocytes, microglia, and endothelial cells comprise the neurovascular unit of the BBB. Blood -brain barrier permeability occurs by endothelial transcytosis regulated by pericytes by at least two mechanisms: 1) by regulating BBB-specific gene expression patterns in endothelial cells and 2) by inducing polarization of astrocyte end-feet surrounding CNS blood vessels. Pericytes can also function in cell therapy via secretion of relevant trophic factors. In a study by Chen et al. , purified human pericytes promoted functional and structural recovery in ischemic heart disease, and this therapeutic potential was partially attributed to the paracrine effects of the transplanted pericytes.

1 They are active in angiogenesis, 2 regulate Jan 29, 2020 Pericytes (PCs) wrap around endothelial cells (ECs) and perform diverse functions in physiological and pathological processes. Although The association of pericytes (PCs) to newly formed blood vessels has been suggested to regulate endothelial cell (EC) proliferation, survival, migration, Jun 28, 2019 Pericytes are multi-functional cells embedded within the walls of capillaries throughout the body, including the brain.

Pericytes regulate the development of organ-specific characteristics of the brain vasculature such as the blood–brain barrier (BBB) and astrocytic end-feet. Whether pericytes are involved in the control of leukocyte trafficking in the adult central nervous system (CNS), a process tightly regulated by CNS vasculature, remains elusive.
Whether pericytes are involved in the control of leukocyte trafficking in the adult central nervous system (CNS), a process tightly regulated by CNS vasculature, remains elusive. Since pericytes cover the vascular wall and play an important role with endothelial cells in the functions of blood-nerve barrier (BNB) (Peltonen et al., 2013), they might also be involved in the cisplatin-induced neuropathy.
