Abstract

Research team head ; Research team member ; Research team member ; Publisher ; 研究種目 : 基盤研究(B)(一般) 研究期間 : 2013~2015 課題番号 : 25293313 研究分野 : 脳神経外科 ; Oncoantigenは, 腫瘍悪性化に関与する抗原として提唱され, 腫瘍発生初期に免疫学的に排除される抗原と異なり, 免疫逃避される可能性が低いため, ワクチンへの応用が期待されている。本研究では, グリオーマの遺伝子・蛋白発現比較解析, 他の癌腫で同定された腫瘍抗原のグリオーマにおける遺伝子・蛋白発現解析, グリオーマにおける機能解析を行った結果, 脳腫瘍oncoantigenとして2つの分子の同定に成功した。これらの分子は, 脳腫瘍組織, 脳腫瘍細胞, 脳腫瘍幹細胞において髙発現を呈し, 脳腫瘍細胞の増殖に関与する。今後は, 同定したoncoantigenを用いた免疫療法の開発を進める予定である。 Oncoantigen are tumor antigens required for the neoplastic process and when cancer vaccine against oncoantigen, the chance that escape immune recognition to tumor should be reduced. In order to identify oncoantigens against glioma, we performed the comparative gene expression analysis of gliomas and also gene expression analysis of known oncoantigens against other cancers in gliomas. Then, functional analysis of oncoantigen candidates selected was performed in glioma cells. We succeeded in identify two oncoantigens against glioma that are expressed highly in malignant glioma tissues, glioma cell lines, and glioma stem cells isolated from glioma patients. These oncoantigens were shown to be involved in the growth of glioma by gene knockdown experiments. Furthermore, in a mouse in vivo glioma model, the gene knockdown of the oncoantigen showed a significant therapeutic effect. We plan to perform an immunotherapy using the oncoantigen identified for the treatment of malignant gliomas.
