背景
- Platelet-derived growth factors (PDGFs) are homo- or heterodimers of four polypeptides, known as A, B, C and D chains. PDGFs usually acts primarily in paracrine manner and may be engaged in autocrine loops in tumors. Five PDGF isoforms (AA, BB, AB, CC and DD) have been identified. PDGFs are primarily synthesized, stored, and released by platelets upon activation. PDGF-A and PDGF-B undergo intracellular activation during transport in the exocytic pathway and PDGF-C and PDGF-B are activated by extracellular proteases. Like PDGF-B, intracellular activation of PDGF-A, by removing the N-terminal sequence, is required for PDGF-A to bind to its receptor. PDGF-A can also be expressed by epithelial cells, smooth muscle cells, and neuronal progenitors. PDGF-AA is well known as a potent mitogen for the proliferation of oligodendrocyte progenitor cells (OPCs). PDGF-AA can promote embryonic forebrain neural stem cells into O4-positive oligodendrocytes by activating Erk pathway. PDGF-AA also plays an important role in directing cell migration during embryonic development and postnatal migration response including wound healing. Chemotaxis abilty of PDGF-AA has been shown on fibroblasts, smooth muscle cells, monocytes, and granulocytes.
