MAGEA3 and neoplasm: In addition, human anti-MAGE-A3271–279-specific T cell clones isolated from bacteriophage-stimulated T cell lines showed high avidity for the MAGE-A3 epitope and were able to kill human MAGE-A3-tumor cell lines expressing a low amount of MAGE-A3271–279 peptide-HLA complex on the surface [53].
