The MHC molecules are divided into 2 classes. The class I molecules are normally expressed on all nucleated cells, whereas the class II molecules are expressed only on the professional antigen-presenting cells (APCs), such as dendritic cells, activated macrophages, and B cells. The physiologic function of the MHC molecules is to present antigenic peptides to T cells. The class I molecules present antigenic peptides from within the cell (eg, self-antigens, intracellular viruses, tumor antigens) to CD8 T cells. The class II molecules present extracellular antigens such as extracellular bacteria to CD4 T cells.
