Detection of Human HLA-DR by Flow Cytometry

Costimulatory profile of mature DCs generated with a 3-day protocol. (A) Shown is the expression of specific surface molecules detected on DCs by flow cytometry in a representative patient sample generated with cocktail RP. (B) Comparison of the expression intensity of the costimulatory molecules CD80 and CD86 and the coinhibitory molecules CD273 and CD274 between HCs and AML patients. The mean fluorescence (MFI) of at least three individual experiments of HC and AML patients were compared using the different maturation cocktails C, CP, R, and RP.

Background: HLA-DR

HLA-DR is a transmembrane human major histocompatibility complex 2 (MHC II) family member and consists of a 34 kDa (alpha) subunit and one of several 28 kDa (beta) subunits. HLA-DR is expressed primarily by B cells and dendritic cells (DC), in which it binds peptides derived from internalized and processed antigenic proteins. It presents these peptides on the cell surface for recognition by the T cell receptor on CD4⁺ T cells. This interaction is central to antigen specificity in the adaptive immune response. HLA-DR alleles, polymorphisms, and aberrant expression are linked to a variety of diseases including autoimmunity and cancer.
