HLA-DR Molecular Targets Overview

HLA-DR (Human Leukocyte Antigen-DR) is a class II molecule located on human chromosome 6 in the MHC region. It consists of a heterodimer of alpha/beta chains encoded by the DRA and DRB genes, and acts as a core antigen-presenting molecule involved in CD4+ T-cell activation. cell activation. Its high polymorphism affects susceptibility to autoimmune diseases (e.g., rheumatoid arthritis, lupus erythematosus) and serves as a key indicator for transplantation mating.
