Definition of MAJOR HISTOCOMPATIBILITY COMPLEX. : a group of genes in mammals that code for cell-surface polymorphic glycoprotein molecules which display antigenic peptide fragments for T cell recognition and aid in the ability of the immune system to determine self from nonself. ADVERTISEMENT.edical Definition of MAJOR HISTOCOMPATIBILITY COMPLEX. : a group of genes in mammals that function especially in determining the histocompatibility antigens found on cell surfaces and that in humans comprise the alleles occurring at four loci on the short arm of chromosome 6âabbreviation MHC.
Almost all cells in the body present antigens-and they present the antigens in a special protein complex called the Major Histocompatability Complex (MHC). This may sound complicated but MHC is simply a group of proteins that captures proteins within the cell and brings them to the cell membrane.his genetic material is expressed into proteins that become part of the surface of the cell, its membrane. The proteins are called antigens in the context of the immune system. All livings things are made of cells, from one cell to millions of cells â including us and the organisms we refer to as pathogens.
