The class II MHC genes code for self receptors recognized by T lymphocytes.
Major Histocompatibility Complex (MHC) Class II molecules are a subset of MHC molecules that are typically only found on specialised antigen-presenting cells like dendritic cells, mononuclear phagocytes, some endothelial cells, thymic epithelial cells, and B cells. These cells are crucial for starting immunological reactions. Class II peptides use extracellular proteins as the source of the antigens they present. An extracellular protein is endocytosed, digested in lysosomes, and the resulting epitopic peptide fragments are loaded onto MHC class II molecules during phagocytosis, which happens before the molecules move to the cell surface.
Hence, MHC II gene code for T cell immune responses.
