Preferred Label : Fc Gamma Receptor-Mediated Phagocytosis Pathway;
NCIt related terms : Fc gamma R-mediated phagocytosis;
Alternative definition : KEGG: Phagocytosis plays an essential role in host-defense mechanisms through the
uptake and destruction of infectious pathogens. Specialized cell types including macrophages,
neutrophils, and monocytes take part in this process in higher organisms. After opsinization
with antibodies (IgG), foreign extracellular materials are recognized by Fc gamma
receptors. Cross-linking of Fc gamma receptors initiates a variety of signals mediated
by tyrosine phosphorylation of multiple proteins, which lead through the actin cytoskeleton
rearrangements and membrane remodeling to the formation of phagosomes. Nascent phagosomes
undergo a process of maturation that involves fusion with lysosomes. The acquisition
of lysosomal proteases and release of reactive oxygen species are crucial for digestion
of engulfed materials in phagosomes.;
