Background
Human platelet-derived growth factor receptor, beta polypeptide (PDGFRB) is also called PDGF-R-beta and PDGFR, is receptor that binds specifically to PDGFB. PDGFRB is a tyrosine‐kinase receptor for PDGF‐B and PDGF‐D. PDGF-BB secreted by endothelial cells binds to PDGFRB on pericytes, causing the activation of downstream signaling pathways to regulate survival, migration, apoptosis, proliferation, and differentiation. PDGF-BB/PDGFRB signaling is essential for the pericytes-regulated BBB integrity in the stage of development, and adulthood. Furthermore, expression of PDGF-BB/PDGFRB is upregulated in CNS after cerebral ischemia in human and animal models, which is involved in tissue responses especially targeting vascular pericytes. The PDGFRB/EZH2 pathway is critical for promoting cardiomyocyte proliferation and heart regeneration, providing a potential target for cardiac repair.
