Summary Introduction
Introduction:
The full form of MHC is the major histocompatibility complex. It plays an important role in generating a cell-mediated and humoral immune response. The two major forms of MHC molecules are class I and II. MHC I can be found on all the nucleated cells.

Empty MHC class I and MHC class II molecules are rapidly removed from the cell surface. This process prevents:
The accumulation of empty MHC molecules on the cell surface which would interfere with T cells recognizing pathogen-derived peptide:MHC complexes
Pathogens from evading the immune response by inducing peptide release from cell surface MHC molecules
MHC class I molecules from being internalized into endosomes and binding endosome-derived peptides
HLA-DM from trafficking to the cell surface with MHC class II
Inappropriate T cell recognition of healthy cells that are not infected, nor have ingested a pathogen
Why would a virus that can interfere with a host cell’s production of MHC class I molecules be at an advantage?
Which of the following steps are part of the processing of antigen by immune cells? Select all that apply.
The vesicle containing the antigen fuses with a lysosome.
Enzymes in the lysosome digest the antigen into components that bind to MHC markers.
The antigen is initially released from the phagocytic cell via exocytosis.
The antigen-MHC complex becomes displayed on the cell's interior.
