major histocompatibility antigens found only on immunocompetent cells, primarily B lymphocytes and macrophages; they are found on molecules consisting of two noncovalently bound chains, the 34,000-dalton α chain and 29,000-dalton β chain, both glycoproteins partially embedded in the cell membrane and both determined by MHC genes. The human HLA-D, -DR, -DQ, -DT, -MB, -MT, and -Te loci are all associated with antigenic determinants on class II antigen molecules.
