The major histocompatibility complex (MHC) is a large locus on vertebrate DNA containing a set of closely linked polymorphic genes that code for cell surface proteins essential for the adaptive immune system. (wikipedia.org)
These cell surface proteins are called MHC molecules. (wikipedia.org)
Later studies revealed that tissue rejection due to incompatibility is only a facet of the full function of MHC molecules: binding an antigen derived from self-proteins, or from pathogens, and bringing the antigen presentation to the cell surface for recognition by the appropriate T-cells. (wikipedia.org)
The presentation of pathogen-derived proteins results in the elimination of the infected cell by the immune system. (wikipedia.org)
Also, at least for MHC I presentation, there has been evidence of antigenic peptide splicing, which can combine peptides from different proteins, vastly increasing antigen diversity. (wikipedia.org)
