Outline of Research at the Start |
実臨床においては抗癌剤だけでなく、血管新生阻害剤や免疫チェックポイント阻害剤が一定の効果を示しているものの、腫瘍微小環境のダイナミックな環境変化には対応できていないのが現状である。この腫瘍微小環境構築には、癌細胞により腫瘍関連マクロファージ(TAM)が誘導され、さらにTAM により誘導される免疫逃避機構により、腫瘍悪性度増強・薬剤耐性能を獲得することが予想される。 本研究では腫瘍微小環境構築のkey regulator であるTAM に着目し、Cancer cell-TAM interaction やTAM を介して誘導される免疫逃避機構の機序解明や、そのクロストークの解除を目的とした治療戦略について検討する。

Outline of Final Research Achievements |
The purpose of this study was to establish the treatment strategy for tumor microenviroment focused on CAF (cancer associated fibroblast)-TAM (tumor associated macrophage) interaction. At first, we identified that in the tumor microenvironment, the release of OPN (osteopontin) from TAM was increased, and this upregulated OPN further upregulated the OPN secretion from CAF cultured with TAM-CM (conditioned medium), leading to increased malignancy of cancer. Next, we demonstrated that CAF promoted the M2 polarization of macrophages and the induced TAM by CAF upregulated the PAI-1 secretion via CXCL12 of CAF-CM. Subsequently, PAI-1 produced by TAM enhanced the malignant behavior of cancer. Consequently, our results suggested that CAF-TAM interaction was correlated with tumor malignancy, the canceling the Cancer cell-CAF-TAM interaction would be a breakthrough for intractable cancer strategy.

Academic Significance and Societal Importance of the Research Achievements |
癌治療において、癌細胞だけでなく腫瘍内血管新生や免疫不全をターゲットとした腫瘍微小環境に対する集学的治療が展開されているが、それらは癌細胞と脈管構成細胞・免疫担当細胞による単一のクロストークをターゲットとしたもので、依然、腫瘍微小環境の一部を攻略しているにすぎない。本研究における癌自体を包括的に捉えた腫瘍微小環境構築におけるCancer cell-TAM interactionの結果は、特にTAMをターゲットとした難治性癌の治療戦略確立のための一助となる可能性がある。
