Anti-CD47 Antagonist Antibody

CD47 (Cluster of Differentiation 47) plays an essential role in cell growth, death, migration, and adhesion. CD47 binding to SIRP-α mediates phagocytosis by sending a “do not eat me” signal to phagocytes. CD47 proteins are often over expressed by tumor cells as a means for them to escape phagocytosis. As a result, cancerous tumor cells have the ability to proliferate and evade the immune system. CD47 signal-regulatory protein alpha (SIRP-α), also known as CD172a, is a cell surface protein expressed mainly by myeloid cells such as macrophages. In the context of a tumor, this signaling aids in tumor evasion of the immune system. Inhibitors of this interaction hold great promise for cancer immunotherapy.
