Outline of Research at the Start

近年、がん免疫療法が「第四の治療法」として注目されている。しかし、その治療効果は限定的であり、老化やがんの発症に伴うT細胞の不可逆的な機能不全、すなわちT細胞の疲弊化 が本治療の効果を減弱させる要因の一つであると考えられている。本研究課題では海外共同研究者の開発したPartial Reprogramming技術を用いて部分的初期化させたT細胞の機能解析およびその分子機構を解明することで、老化やがんの発症に伴うT細胞の疲弊を解除する方法を明らかにし、効果的ながん免疫細胞療法の確立に有効な新規のT細胞再生技術を開発することを目的とする。

Outline of Final Research Achievements

In recent years, cancer immunotherapy has been recognized as the "fourth therapy." However, its effectiveness is limited due to T cell exhaustion. This study aimed to develop a novel T cell rejuvenation technique for cancer immunotherapy by transiently expressing Yamanaka 4 factors and inducing partial reprogramming to alleviate T cell exhaustion. The findings demonstrated that partial reprogramming led to T cell proliferation, reduced exhaustion markers, and increased anti-tumor activity in mice. Similar effects were observed in human T cells, suggesting that partial T cell initialization with Yamanaka 4 factors could rejuvenate T cells.

Academic Significance and Societal Importance of the Research Achievements

本研究成果はこれまで不可逆的な細胞変化であると考えられてきたT細胞の疲弊、老化は山中4因子の一過性発現による部分的初期化により若返りさせることができる可能性を示した研究成果である。この発見は近年「第四の治療法」として注目されているがん免疫療法において、がん患者、高齢者において疲弊しているT細胞を若返らせる技術として応用できる可能性がある。
