Recombinant human HLA-DPB1 protein is a synthesized form of the HLA-DPB1 antigen, a critical component of the human major histocompatibility complex (MHC) class II molecules. HLA-DPB1 is located on chromosome 6 and plays a pivotal role in immune regulation by presenting exogenous antigens to CD4+ T cells, initiating adaptive immune responses. It consists of α and β chains, with polymorphisms in the β chain (encoded by HLA-DPB1 alleles) influencing peptide-binding specificity and immune compatibility. HLA-DPB1 allelic diversity is linked to disease susceptibility, transplant outcomes, and autoimmune disorders like rheumatoid arthritis or type 1 diabetes.
Recombinant HLA-DPB1 is typically produced in vitro using expression systems (e.g., mammalian or insect cells) to ensure proper folding and glycosylation. It serves as a tool for studying alloreactivity in hematopoietic stem cell transplantation, where HLA-DPB1 mismatches may trigger graft-versus-host disease (GVHD) or graft rejection. Researchers also use it to investigate T cell epitope mapping, autoimmune mechanisms, and vaccine development. Additionally, it aids in developing HLA typing assays and therapies targeting MHC class II pathways. Due to its clinical relevance in transplantation immunology and personalized medicine, recombinant HLA-DPB1 remains a key focus in immunology research and therapeutic innovation.
