Abstract:
MAGE-n is a new member of MAGE gene family and has been demonstrated closely associated with hepatocellular carcinoma (HCC). In this study, MAGE-n-derived peptide-specific cytotoxic T lymphocytes (CTL) were induced from the peripheral blood mononuclear cells of healthy donors by multiple stimulations with HLA-A2-restricted MAGE-n peptide-pulsed T2 cells. The induced CTLs exhibited specific lysis against T2 cells pulsed with the peptide and HLA-A2+ HCC cells expressing MAGE-n, while HLA-A2+ HCC cell lines that did not express MAGE-n could not be recognized by the CTLs. The peptide-specific activity was inhibited by anti-MHC class I monoclonal antibody. These results suggested the MAGE-n peptide could be a potential target of specific immunotherapy for HLA-A2 patients with HCC.
