Phagocytic processing of antigens for presentation by MHC molecules.
Phagocytosis plays a major role in the defence of higher organisms against microbial infection not only by allowing ingested microbes to be destroyed by microbicidal mechanisms, but also by providing the basis for processing of their antigens to forms that generate immune responses. This article examines the role of the phagolysosome in antigen processing, and discusses the contributions of both MHC class II and MHC class I molecules to the presentation of antigens derived from phagocytosed material.
