Direct Tumor Suppression by Anti-Basigin Antibody and Enhancement of Macrophage-Mediated Cancer Cell Phagocytosis under SIRPα Blockade
The transmembrane protein CD47 expressed on tumor cells suppresses Fcγ receptor–mediated antibody-dependent cellular phagocytosis (ADCP) through its interaction with signal regulatory protein α (SIRPα), a transmembrane protein expressed on phagocytic cells such as macrophages. Although blockade of the CD47–SIRPα intera...
