Outline of Research at the Start

抗PD-1抗体の効きやすさや効きにくさを決めるメカニズムについては基礎研究レベルで示されているが、実際に抗PD-1抗体投与を受けた患者のがん組織内で起きている現象を直接解析した研究は少ない。そこで本研究では、切除可能な皮膚転移を含む、多発転移を持った進行期メラノーマ患者を対象に、抗PD-1抗体治療前の組織および縮小中や増大に転じた組織において、浸潤するT細胞と癌細胞の機能、性質などを網羅的に解析して、治療の選択により役立つ指標を探す。

Outline of Final Research Achievements

In this study we have explored molecules that play important roles in activation of tumor specific T cells. Eventually, we have identified several molecules selectively expressed on tumor specific T cells, and controlling activation of T cells. We have shown that one of such molecules, TIGIT attenuate the effect of anti-PD-1 therapy via interaction with CD155 on tumor cells.

Academic Significance and Societal Importance of the Research Achievements

現在、抗PD-1抗体の臨床判断に役立つような鋭敏なバイオマーカーはない。その理由として、腫瘍内の腫瘍特異的T細胞の性質や機能を直接に評価する研究がほとんど行われてこなかったことが挙げられる。今回の研究では、腫瘍内の腫瘍特異的T細胞を正確に同定してフォーカスし、網羅的に解析した。解析対象を重要なT細胞のみに絞ることで、従来では見つけることができなかった鋭敏なバイオマーカーや治療標的としての候補分子を発見した。
