HLA-DR (Human Leukocyte Antigen – DR isotype) is a major histocompatibility complex (MHC) class II antigen presentation molecule, critical for the activation of lymphocytes and the coordinating of adaptive immune responses. HLA DR antigen is required for tumor-associated antigen recognition by CD4+ T cells. It is normally expressed on antigen-presenting cells including monocytes, macrophages, dendritic cells and B cells, but expression can be induced on epithelial cells and tumor cells in response to inflammatory conditions.15,16
