Fc gamma receptor-mediated effector function

Molecular classification
Immunoglobulin superfamily, Receptor
01

Overview

Fc gamma receptor-mediated effector function refers to the biological activities triggered when Fc gamma receptors (FcγRs) on immune cells bind to the Fc region of immunoglobulin G (IgG) antibodies. This interaction is central to linking humoral immunity (antibody responses) with cellular immune mechanisms, enabling processes such as phagocytosis, antibody-dependent cellular cytotoxicity (ADCC), and modulation of inflammatory responses. It is critical for the efficacy of many therapeutic monoclonal antibodies used in cancer therapy.
