Background InformationHLA-DR is a member of MHC class II glycoproteins which bind intracellularly processed peptides and present them to the Th cells. HLA-DR is composed of 36 kDa α chain and 27 kDa β chain, both anchored in the plasma membrane. Together with other MHC II molecules HLA-DR plays a central role in the immune system.
