CD47, Leukocyte surface antigen CD47, is also known as integrin-associated protein (IAP) or protein MER6.CD47 belongs to the immunoglobulin superfamily and is widely expressed on the surface of a variety of cells, and is encoded by the human CD47 gene.
The mechanism of action of CD47 involves interactions with signal-regulated protein α, which negatively regulates phagocytosis through phosphorylation and activation of SIRPα, which recruits and activates SHP phosphatase, which in turn mediates dephosphorylation of myosin 2a, leading to diminished phagocytosis of cells carrying CD47 by macrophages, thereby negatively regulating phagocytosis.
CD47 plays a critical role in maintaining immune tolerance in benign cells, ensuring that autologous cells are not inappropriately phagocytosed. However, many different types of cancer cells use high expression of CD47 to mediate immune escape from phagocytosis by macrophages. Blockers of CD47 are being developed to promote phagocytosis of tumor cells by macrophages as a potential strategy for cancer therapy.
