FCGR2A and cancer: Important endocytic receptors expressed at high levels by inflammatory cells and at lower levels by type 2 DCs are members of the immunoglobulin Fc Receptor (FcR) family.[16] FcγR mediates the uptake of immune complexes (ICs) and of dead cells opsonized by antibodies directed against cell surface proteins.[17] Such events occur during viral infections or after the administration of tumor‐targeting monoclonal antibodies (mAbs) used in cancer therapy.
