WebDec 21, 2024 · Interaction with C1q initiates activation of complement. Binding to various Fc receptors on leucocytes induces antibody-dependent cell-mediated cytotoxicity (ADCC) or antibody-dependent cell-mediated phagocytosis (ADCP). Binding to the FcRn receptor is responsible for the comparatively long half-life of IgG. WebThe Fc-gamma receptor is expressed on many immune cells and binds to monomeric IgG with high affinity, thereby modulating the immune response. Measuring the affinity of antibodies for Fc receptors has become an integral part of biotherapeutic drug development.
