Human Leukocyte Antigen A*02 Complex Presenting MAGE-A4 Peptide

The Human Leukocyte Antigen A*02 Complex Presenting MAGE-A4 Peptide is an immune recognition unit consisting of the HLA-A*02 allele and a peptide derived from the melanoma-associated antigen gene A4 (MAGE-A4). This complex presents tumor-associated antigens to CD8+ T cells, triggering a targeted immune response. It is a key target for cancer immunotherapies, where therapies such as engineered T-cell receptors (TCRs) recognize and target tumor cells displaying these complexes. Patient selection for such therapies depends on MAGE-A4 expression in tumors and compatible HLA-A*02 alleles. This complex plays a critical role in immune recognition, particularly in cancer immunotherapy.
