Outline of Research at the Start

固形がんを標的とした現状の遺伝子改変T細胞輸注(TCR-T)療法の効果は未だ満足できるものではない。その主要な要因として「腫瘍における抗原不均一性(Heterogeneity)」が考えられる。研究代表者らは大腸がんTIL中の「腫瘍反応性を有する」変異抗原特異的CD8+T細胞に特徴的な細胞表面分子を同定した成果を基に、同一患者末梢血中に存在する、同一のTCRを発現するCD8+T細胞の発現分子バイオマーカーを同定する。この技術を用いて患者末梢血中から腫瘍反応性CD8+T細胞を網羅的に取得・利用し、手術不耐患者をも対象可能とする「次世代型個別化TCR-T療法」の実現に向けた基盤を確立する。

Outline of Final Research Achievements

We have obtained and analyzed tumor-reactive CD8+ TILs from colorectal cancers and renal cancers, and confirmed that many of the tumor-reactive CD8+ TILs from colorectal cancers recognize mutated antigens, and that PD-1, 4-1BB, and CD9 are useful markers for identifying mutated antigen-specific CD8+TILs. In addition, analysis of RNA from over 200 cases of colorectal tumor tissues showed that cases with high levels of 4-1BB expression in tumor tissues had extended OS/DFS. Furthermore, we have obtained results that CD81, which belong to the tetraspanins along with CD9, can be promising indicator of mutated antigen-specific CD8+ T cells in spleen cells. We have obtained important results that will serve as a foundation for identifying the phenotype of mutated antigen-specific CD8+ T cells in PBMCs.

Academic Significance and Societal Importance of the Research Achievements

変異抗原特異的なCD8+T細胞由来のTCRを用いた、多数の変異抗原を標的とする完全個別化TCR-T療法は“治癒”を望める有望な治療法となり得る。現時点ではTIL中の変異抗原特異的CD8+T細胞の同定においてさえ容易ではないが、本研究において多数の患者が存在する大腸がんを解析し、腫瘍組織中の変異抗原特異的CD8+TILの同定に有用となる複数の細胞表面分子マーカーの同定に成功した。本研究で得られた技術基盤は、今後のより侵襲の低い患者PBMCからの変異抗原特異的CD8+T細胞、及びそのTCRの迅速取得に重要な技術基盤になることが予想され、社会的な意義が大きいと考えられる。
