| Outline of Final Research Achievements |
Three candidate peptides were identified by peptide binding assay. Of the three HLA-A24 restricted peptide, DNAJB8_22(9) (AYRKLALRW) and DNAJB8_99(9) (IFREFFGGL) induced antigen specific cytotoxic T lymphocytes (CTLs), which presented peptide specific IFN-γ secretion and cytotoxic activity. The sequence of DNAJB8_22(9) is completely identical to murine DNAJB8. Since HLA-A24 restricted peptides were tended to be compatible with binding to murine MHC class I molecule, H-2Kd, we evaluated CTL induction in vivo by immunization of DNAJB8_22(9) in Balb/c mouse model. DNAJB8_22(9) immunization could also induced DNAJB8 specific IFN-γ production and cytotoxic activity in mice.
