Keywordsネオアンチゲン / オルガノイド / ペプチドミクス解析 / 遺伝子変異 / がん免疫治療 / HLA分子 / 質量分析計
Outline of Research at the Start

がん細胞特異的な遺伝子変異に由来する抗原(ネオアンチゲン)は強い免疫反応を誘導する。本研究では、進行がん患者にも臨床応用できるように、3次元培養(オルガノイド)した腫瘍組織から最先端の質量分析(ペプチドミクス解析)技術を用いて、ネオアンチゲンを効率的に同定する手法を確立する。また、同定したネオアンチゲン特異的T細胞の抗腫瘍効果を確認する。本研究の成果は、“がんの免疫学的病態の解明”に寄与するとともに、“ネオアンチゲンを標的とした個別化がん免疫治療”の臨床開発を加速するものと期待される。

Outline of Final Research Achievements

No reliable methods have been established to identify gene mutation-derived antigens (neoantigens) that play a central role in anti-tumor immune responses. In this study, we developed a method to efficiently and comprehensively identify neoantigen peptides presented on HLA molecules on the surface of cancer cells by mass spectrometry (peptidomic analysis) using tumor organoid cultures. In addition, tumor-infiltrating lymphocytes isolated from tumor tissues were examined for their reactivity to organoid tissues and neoantigens.

Academic Significance and Societal Importance of the Research Achievements

がん免疫療法開発において、がん抗原、特にネオアンチゲンの同定効率の低さが課題とされている。本研究では、微量の腫瘍組織から拡大培養したオルガノイド組織を用いて、ネオアンチゲンを効率的・網羅的に同定する手法を開発したが、その成果は“がんの免疫学的病態の解明”に寄与するとともに“ネオアンチゲンを標的とした個別化がん免疫治療(がんワクチンやT細胞受容体遺伝子導入T細胞療法)”の開発を推進するものと期待される。
