HLA-DMA (Major Histocompatibility Complex, Class II, DM Alpha): HLA-DMA is a key component of the MHC class II molecule involved in the immune system's antigen presentation process. It plays a crucial role in the regulation of peptide loading onto MHC class II molecules, ensuring that immune cells can present antigens properly to T cells. This process is vital for the immune response to pathogens and the maintenance of immune tolerance. Alterations in HLA-DMA function can affect immune system efficiency and have been associated with various autoimmune diseases, emphasizing its importance in immune regulation and disease susceptibility....
