Outline of Research at the Start

プロスタグランジン(PG)は、その産生酵素ががんで高発現しており、アスピリンなどの阻害薬が様々ながんの発症、再発を抑制することから、がんの増殖進展に強く働いていると考えられています。本研究では、EP2とEP4というPGの作用を伝える2つの受容体に注目して、がん、特に、その免疫回避での、働きを、動物モデルで解明、その結果をヒトのがんに外挿してEP2阻害薬やEP4阻害薬のヒトがんでの応用を促進します。

Outline of Final Research Achievements

In this study, we analyzed immune cells infiltrating mouse LLC1 tumor as well as human tumors by scRNAseq and examined the roles prostaglandin E2 (PGE2)-EP2/EP4 signaling plays in immune evasion in tumor microenvironment (TME). In the former, we found that this signaling recruits and activates regulatory T cells in tumor, while the same signaling acts on myeloid cells to stimulate inflammation and angiogenesis, thus recapitulating the feature of TME, that is, the simultaneous presence of immune-evasion and inflammation. In the latter, we found that the PGE2-EP2/EP4 signaling impairs bioenergetics and ribosome biogenesis in various tumor-infiltrating immune cells by suppressing both glycolysis and mitochondrial respiration as well as c-Myc signaling, making, for example, CD8+ T cells ineffective in their expansion, migration and tumoricidal activity.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的意義は2つある。一つは、アスピリンなどのPG生合成阻害薬の抗腫瘍作用のメカニズムをPGの腫瘍微小環境での作用から明らかにしたことである。これはアスピリンがどうして腫瘍死のリスクを軽減するかという永年の謎に一つの回答を与えたことになる。もう一つは、浸潤免疫細胞でのPGE2依存性のエネルギー代謝抑制を明らかにして、腫瘍微小環境には既知の免疫check pointや物理的バリアーに加えて、代謝バリアーという新しいバリアーが存在することを示したことである。社会的には、本研究は、現在実施されているEP2/EP4拮抗薬の抗腫瘍作用の臨床治験に理論的根拠を与え、促進すると期待される。
