Platelet-derived growth factor subunit B(PDGFB) is a cysteine knot type growth factor subunit encoded by PDGFB gene, which is mainly synthesized and secreted by activated platelets, vascular endothelial cells and glioma cells, and released into extracellular microenvironment in the form of PDGF-BB homodimer. Compared with PDGFA subunit with weak proliferative activity, PDGFB homodimer can specifically activate PDGFRβ receptors on the surface of pericytes, fibroblasts and glial precursor cells, and effectively start the signal pathway of cell migration and extracellular matrix deposition. In the process of physiological vascular repair, PDGFB secreted temporarily by the body can effectively recruit vascular wall cells, cover the new microvascular wall, stabilize the damaged vascular structure, and ensure the orderly completion of vascular remodeling. However, in the microenvironment of glioma and fibrotic lesions, PDGFB continues to be abnormally overexpressed, which constantly stimulates abnormal proliferation of peripheral cells and induces excessive accumulation of collagen, thus accelerating tumor pathological angiogenesis and promoting the progress of organ scarring and fibrotic lesions. PDGFA can't compensate the specific signal activation function of PDGFB biased towards PDGFRβ, and the loss of PDGFB gene will lead to the defect of perivascular cell coverage and abnormal development of microvascular structure in embryos. Targeted neutralization of PDGFB can effectively block the progress of glioma and alleviate the degree of tissue fibrosis, which is the core irreplaceable target of matrix remodeling mechanism research and anti-tumor and anti-fibrosis targeted drug screening.
As a secreted growth factor, PDGFB can form a stable BB homodimer in the interstitial tissue. Relying on the conservative cysteine knot folding structure, PDGFB specifically binds to PDGFRβ tyrosine kinase receptor on the surface of mesenchymal cells and initiates a series of downstream biological effects. Its unique action mode of targeting and activating peripheral cells forms obvious functional differentiation with PDGFA, which is the core signal pathway for the body to recruit vascular wall cells and regulate vascular maturation. The matrix activation effect mediated by PDGFB can closely relate the platelet-derived injury stress signal with the process of tissue fibrosis and vascular remodeling, and dynamically balance the physiological wound repair with pathological scar hyperplasia and malignant progress of tumor according to the degree of tissue injury. This molecule is widely involved in the maturation and development of embryonic blood vessels, abnormal proliferation of glioma matrix and the progress of multiple organ fibrosis such as kidney and lung. The dysfunction of PDGFB will seriously hinder the process of pericyte recruitment, destroy the stability of microvascular network, and lead to vascular structural development defects and tissue repair obstacles. To sum up, PDGFB is the key target for the mechanism research of platelet-derived growth factor and the research and development of targeted therapy for fibrotic diseases and tumors.
