Immunoglobulin transport across polarized epithelial cells

Raul Rojas et al. Nat Rev Mol Cell Biol. 2002 Dec.

Abstract

IgA, IgG and IgM are transported across epithelial cells in a receptor-mediated process known as transcytosis. In addition to neutralizing pathogens in the lumen of the gastrointestinal, respiratory and urogenital tracts, these antibody-receptor complexes are now known to mediate intracellular neutralization of pathogens and might also be important in immune activation and tolerance. Recent studies on the intracellular transport pathways of antibody-receptor complexes and antibody-stimulated receptor-mediated transcytosis are providing new insight into the nature and regulation of endocytic pathways.
