WebDec 19, 2024 · In brief, the immune cell response is mediated by four activating receptors — FcγRI, FcγRIIA, FcγRIIC (encoded by a pseudogene that is expressed only in select individuals owing to allelic... WebFc receptors (FcR) are expressed on immune cells and bind to the Fc tail of antibodies. This interaction is essential for FcR-mediated signaling and triggering of cellular effector functions. FcR activation is tightly regulated to prevent immune responses by non-antigen bound antibodies or in the absence of 'danger signals'.
