PG - 629-36 AB - One promising modality in the treatment of malignant glioma is specific immunotherapy. However, this modality requires information about target antigens and their epitope peptides that are recognized by T cells. In this study, we searched for new target candidates in specific immunotherapy for malignant glioma by utilizing cDNA microarray technology to compare gene expressions in malignant glioma tissues to those in benign glioma and a panel of normal tissues. The selected genes included three members of the kinesin superfamily proteins (KIFs): KIF1C, KIF3C, and KIF21B. RT-PCR showed that these three genes were expressed in the majority of glioma cell lines. These antigen-derived 25 peptides, which had the ability to bind to human leukocyte antigen (HLA)-A24 molecules, were first screened for their ability to be recognized by the immunoglobulin G of glioma patients, and then tested for their potential to induce peptide-specific and glioma-reactive cytotoxic T lymphocytes (CTLs) from the peripheral blood mononuclear cells of HLA-A24+ glioma patients. The results showed that the KIF1C149-158 and KIF3C512-520 peptides efficiently induced HLA-A24-restricted and glioma-reactive CD8+ T cells. These results suggest the existence of KIF-reactive CTL precursors in glioma patients, and should facilitate the development of specific immunotherapies for malignant glioma.
