HLA-DR Antigens

A group of D-related human leukocyte antigens that are polymorphic glycoproteins found on lymphoid cells. They consist of alpha and beta chains and their inheritance differs from that of the DQ and DP antigens; their presence seems to be associated with certain skin diseases like pemphigus vulgaris, dermatitis herpetiformis, and type I diabetes.
