HLA-C (Human Leukocyte Antigen C): HLA-C belongs to the MHC class I family, playing a vital role in the immune system by presenting endogenous peptide antigens to CD8+ T cells. It is also important for natural killer (NK) cell regulation through its interaction with KIR receptors. HLA-C's expression levels and allelic diversity are key factors in immune response effectiveness, affecting susceptibility to infections, autoimmune diseases, and outcomes in transplantation. Its role in immune surveillance and tolerance highlights its importance in health and disease....
