Numerous immunomodulatory antibodies for cancer treatment have been developed following the discovery of negative regulators of antitumour immunity such as programmed cell death protein 1 (PD1) and cytotoxic T lymphocyte-associated antigen 4 (CTLA4). The efficacy of these antibodies is determined not only by their ability to block or engage their target but also by their interactions with Fcγ receptors (FcγRs). This Review outlines our current knowledge of these interactions and discusses how we can use this knowledge to generate more effective cancer immunotherapies in the future.
