Question

Cell-surface receptors that bind the Fc portion of IgG molecules. Most of these receptors bind only aggregated IgG, allowing them to discriminate bound antibody from free IgG. Expressed variously on phagocytes, B\xa0lymphocytes, NK cells, and follicular dendritic cells, these receptors have a key role in humoral immunity, linking antibody binding to effector cell\xa0functions
