Here, we review PDGF-B and PDGF-R biology with special reference to their functions in brain-blood vessel development, pericyte recruitment and the 

Pericytes have various functions in CNS such as they are source of BBB-specific enzymes, have potential to modulate endothelial permeability, stabilize microvessel wall, and promote angiogenic processes (Daneman and Prat, 2015). Pericytes create an interface between the circulatory system and surrounding tissue (Hirschi and D’Amore, 1996).

Migratory function: Pericyte movement to endothelial cells during vascular development is mediated by endothelial-derived PDGF-β and PDGF-β receptors expressed by pericytes. 7 Pericyte-to-endothelial migration is readily demonstrable in cell culture preparations using in vitro capillary-like structures, as shown in Figure 3. 8 After traumatic brain injury, approximately 40% of brain 2013-03-28 · Pericytes play essential roles to maintain functional vessels to support tumor growth. Tumor pericytes are thought to be derived from their progenitors from the surrounding normal tissue or from the bone-marrow-derived cells homing in tumors after treatments (De Palma et al., 2005; Du et al., 2008). 2018-02-22 · Brain pericytes ensheathe the endothelium and contribute to formation and maintenance of the blood–brain-barrier. Additionally, pericytes are involved in several aspects of the CNS immune response including scarring, adhesion molecule expression, chemokine secretion, and phagocytosis. Pericytes are known to play a key role in the development of cerebral microcirculation but their function in the adult brain and during aging is not clear.

Vascular Pericytes to Support Vessel Function and Tumor Growth Lin Cheng,1,7 Zhi Huang,1,7 Wenchao Zhou,1 Qiulian Wu,1 Shannon Donnola,1 James K. Liu,2 Xiaoguang Fang,1 Andrew E. Sloan,3 Yubin Mao,4 Justin D. Lathia,1 Wang Min,5 Roger E. McLendon,6 Jeremy N. Rich,1 and Shideng Bao1,* The brain pericytes function as oxygen sensors and respond to hypoxia. They are regulated by hypoxia-inducible factor (HIF)-2 and prolyl-4-hydroxylase (PHD) 2 and 3. 1 View large Download PPT In essence, pericytes seem important as structural support in the microcirculation and in BBB function. Pericytes have been considered to be significant in the pathogenesis of tissue damage in hypoxia, hypertension, diabetic retinopathy, trauma, Alzheimer’s disease, multiple sclerosis, and in CNS tumor formation [7, 12 13 14]. It is generally thought that CCL2 is produced by astrocytes, resident microglia, infiltrating macrophages, and, to a lesser extent, endothelial cells in the brain.

The role of pericytes in blood-brain barrier function and stroke. Central nervous system pericytes have critical and complex inductive, structural, and regulatory roles interacting with other cell types of the neurovascular unit, especially endothelial cells and astrocytes.

To characterize if brain pericytes may acquire an anti-inflammatory  Aug 9, 2017 Adequate blood flow is essential to brain function, and its disruption is an early indicator in diseases, such as stroke and diabetes. However, the  Pericytes (PCs) are specialized cells that are located around blood vessels and have numerous important functions.

Pericytes are cells that reside on the wall of the blood vessels and their primary function is to maintain the vessel integrity. Recently, it has been realized that pericytes have a much greater role than just the maintenance of vessel integrity essential for the development and formation of a vascular network.

Pericytes are periendothelial mesenchymal cells residing within the microvasculature. 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.
