HLA-DR HLA-DR is a MHC class II cell surface receptor encoded by the human leukocyte antigen complex on chromosome 6 region 6p21.31. The complex of HLA-DR and its ligand, a peptide of 9 amino acids in length or longer, constitutes a ligand for the T-cell receptor. HLA were originally defined as cell surface antigens that mediate graft-versus-host disease, which resulted in the rejection of tissue transplants in HLA-mismatched donors.
definition of the HLA. On 31 March 1995, this definition was presented to an Architecture Management Group (AMG) formed to develop the HLA from this initial definition. The AMG developed the architecture based on cooperative efforts to apply the HLA in a series of prototypes designed to ensure the HLA addresses the broad set of application requirements.
