Outline of Final Research Achievements

We investigated whether it is possible to increase the therapeutic efficacy of immune checkpoint inhibitors via induction of cancer cell-specific killer T cells. When the antigen that induces killer T cells and IL-2 were introduced into cancer cells and transplanted into mice, the cancer cells disappeared completely. These results suggest that the transduced antigen triggered the attack on cancer cells via induction of killer T cells, which in turn exposed the antigen of cancer cells and triggered induction of killer T cells. We found cancer treatment strategies utilizing killer T-cell induction can be elucidated and may enhance the efficacy of immune checkpoint inhibitors.

Academic Significance and Societal Importance of the Research Achievements

がん治療領域において免疫チェックポイント阻害剤の与える影響は非常に大きい。我々は体内でがん細胞特異的なキラーT細胞を増やし、既存の薬の効果を増強させることを考えた。本研究成果は、がん細胞に対して直接攻撃するものではなく、がん細胞に新たな抗原を発現させることで抗原に対するキラーT細胞の誘導を介して攻撃し、次にがん細胞のネオ抗原に対するキラーT細胞の誘導も引き起こしがん治療および再発するがんに対するワクチン効果を獲得したことを示した点で意義がある。また本システムは特定のがん種だけでなく、多くのがんに対して適応できることが期待される。
