It is my understanding (as a graduate student in a lab which studies
antigen processing and presentation) that the only known function of the
MHC proteins is to present peptide antigens for recognition by T cell
receptors. Class I MHC is responsible for presenting peptides derived
from proteins produced inside the cell (including viral proteins), while
Class II MHC appears to be responsible for presenting peptides derived
from cell-external (and perhaps cell-surface as well) proteins, including
those phagocytosed by macrophages. If you have more specific questions,
feel free to e-mail me at the address below.
