Abstract
The MHC-class-I-like Fcgamma receptor FcRn recycles immunoglobulin (Ig)G from most cells and transports it bi-directionally across epithelial barriers to affect systemic and mucosal immunity. Recent studies have shown that FcRn rescues IgG from intracellular lysosomal degradation by recycling it from the sorting endosome to the cell surface. Most recycling vesicles fuse completely with the plasma membrane in a classical pattern of exocytosis. Similar to the process seen for neurotransmitter release at synaptic junctions, other vesicles fuse only partially, releasing FcRn-IgG complexes to mix into the plasma membrane in cycles of 3-4s over prolonged periods of time.Entities:
