Outline of Final Research Achievements |
The aim of this study was to establish an efficient HPV type 16-targeting cancer immunotherapy. HPV16-derived viral proteins E6 and E7 are expressed in cancerous cells through the progression of the disease and have a role in carcinogenesis but are not expressed in normal cells. In this study, we generated a novel HPV 16 E6 and E7 gene plasmid containing oligomannose liposomes (OML-HPV). We compared the cytotoxic T lymphocyte (CTL) induction efficiency of OML-HPV and that of standard liposome-HPV16 E6 and E7 DNA complex. HPV16 E6-specific CTLs could be generated from HPV 16-positive cervical carcinoma patient's peripheral blood mononuclear cells by stimulating OML-HPV, but could not by stimulating standard liposome-HPV 16 E6, E7 DNA complex. These results indicate that OML-HPV is a more effective approach than DNA vaccination using standard liposomes, and that a novel HLA-A24-restricted peptide, E6 66-74, might be a suitable target of cervical cancer immunotherapy.
