Outline of Research at the Start

腫瘍間質の大部分を占める線維芽細胞は癌関連線維芽細胞CAFと呼ばれ、正常部の線維芽細胞に比して活性化している。われわれは、CAFが癌細胞の悪性化・癌幹細胞様形質獲得に関与することを明らかにした。さらに近年、CAFによる免疫抑制ネットワークの形成が注目されている。今回、我々が考案した癌周囲微小環境再現モデルを用いて、肺癌微小環境を構築するCAFを抑制することで、癌細胞悪性化・癌幹細胞様形質獲得・免疫抑制ネットワークを制御することができるかを明らかにし、新たな肺癌治療の開発を提唱する。

Outline of Final Research Achievements

In the tumor microenvironment of non-small cell lung cancer (NSCLC), cancer-associated fibroblasts (CAFs) interact with lung cancer cells via the TGF-β-IL-6 axis to control epithelial-mesenchymal transition (EMT), resulting in acquisition of malignancy and treatment resistance. CAFs regulated the cytotoxic activity of immune cells, creating a microenvironment of immune tolerance. We also showed that antifibrotic drugs or antibody therapy aimed at CAFs could be as a new lung cancer treatment. As we focused on several roles of CAFs in NSCLC tumorigenesis, owing to their heterogeneity, molecular markers of CAFs were elucidated to better classify tumor-promoting subtypes and facilitate the establishment of CAF-specific targeted therapies. Results thus far obtained have shown that CAF-targeted cancer treatment can suppress EMT, and also regulate the niche of cancer stem cells and the immunosuppressive network, thus may be found useful for cancer treatment through multiple mechanisms.

Academic Significance and Societal Importance of the Research Achievements

近年、癌周囲微小環境を構築する細胞が癌の進展を多面的に促進させることが実証されつつあり、本研究によって癌関連線維芽細胞CAFを標的とした肺癌治療の有用性が示された。癌周囲微小環境内の免疫状態の解析から、抗腫瘍免疫に対するCAFを中心とした癌周囲微小環境内の意義を明らかにできる可能性が示唆された。遺伝子異常の頻度が高く薬剤耐性を生じやすい癌細胞に比較して、CAFを標的とした治療は抵抗性を生じにくいと予測され、既存の癌治療に相乗効果を見込め、CAFを標的とした治療を組み合わせることで治療耐性化を阻害でき、効果増強による投与量の減量、副作用の減少、投与期間短縮につながる可能性がある。
