Fc receptors bind to antibodies that are attached to infected cells or invading pathogens. Their activity stimulates phagocyticor cytotoxiccells to destroy microbes, or infected cells by antibody-mediated phagocytosisor antibody-dependent cell-mediated cytotoxicity. See more In immunology, a Fc receptor is a protein found on the surface of certain cells – including, among others, B lymphocytes, follicular dendritic cells, natural killer cells, macrophages, neutrophils, eosinophils, basophils, … See more Fc receptors are found on a number of cells in the immune system including phagocytes like macrophages and monocytes See more On phagocytes When IgG molecules, specific for a certain antigen or surface component, bind to the pathogen with their Fab region (fragment antigen binding region), their Fc regions point outwards, in direct reach of phagocytes. … See more There are several different types of Fc receptors (abbreviated FcR), which are classified based on the type of antibody that they recognize. The … See more Activation Fc gamma receptors belong to the group of non-catalytic tyrosine-phosphorylated receptors which share a similar signalling pathway involving phosphorylation of tyrosine residues.

WebNov 1, 2024 · The first mechanism of ADE is dependent on FcR (Figure 1 A).FcRs are mainly distributed on immune cells and are receptors targeting the Fc portions on antibodies (Dustin, 2016).In this FcR-mediated ADE, the viral surface protein combines with the antibody to form a virus–antibody complex. WebThe first is the specific binding of the Fc fragment of the antibody to the Fc Receptor expressed on some cells. This protein is critical for the process of destroying microbes or other cells that have been targeted by the organism’s antibodies, either through phagocytosis or cell-mediated cytotoxicity.
