Outline of Research at the Start

がん免疫療法の効果が証明されたが、その効果は満足のいくものではない。腫瘍浸潤リンパ球(TIL)が抗腫瘍免疫応答の本態解明に重要で、我々はTILの解析から腫瘍を直接攻撃する腫瘍特異的T細胞を正確に同定した。さらに、腫瘍「周辺」環境を1細胞シークエンスして、腫瘍「周辺」環境にも特異的T細胞が存在し、そこではT細胞の長期生存に関わる遺伝子が高発現していることを見出した。そこで時空間的に発現調整できるマウスを用いて、腫瘍「周辺」環境での時空間的T細胞分化の抗腫瘍免疫応答での役割を解明する目的で本研究を計画した。腫瘍「周辺」環境という新たな概念を提唱し、新規バイオマーカー・治療に繋がる可能性がある。

Outline of Final Research Achievements

In previous studies, we found that anti-senescence molecules and mitochondria in the tumor "peripheral" environment could be related to antitumor immunity. In this study, we introduced the identified genes into T cells, clearly showing increased activation. In addition, T cells with mitochondrial abnormalities were senescent with metabolic abnormalities and impaired activation and memory formation. We attempted spatial gene regulation in immune cells using our original TRE-PA-Cre system, but many immune cells died after blue light irradiation, making it difficult to use this systme. In contrast, T cell-specific conditional knockout mice showed reduced anti-tumor immune response including durable response, suggesting the importance of these factors.

Academic Significance and Societal Importance of the Research Achievements

抗腫瘍免疫応答では腫瘍局所の免疫応答ばかりが注目されてきたが、本研究成果は周辺の環境も重要であることを証明することができた。特に同定した遺伝子やミトコドリア機能に関しては、がん免疫療法の新たなバイオマーカーや、細胞療法などに応用できる可能性がある。また手術による切除範囲に関しても一石を投じることができるような成果である。マウスの樹立は今回は難しかったが、今後も時空間的制御に利用できるような系の構築を目指していきたい。
