Outline of Research at the Start

S100A8/A9は、好中球の細胞内タンパク質の約50%を占めるタンパク質であり、炎症環境において強く発現が誘導され、がん微小環境の構築に重要な役割を果たす。
申請者らは、S100A8/A9のヘテロダイマー構造特異的なモノクローナル抗体および複数のS100A8/A9受容体の細胞外領域と抗体のFc領域を融合させたタンパク質をがん転移治療薬として開発した。
本申請では、がん転移前微小環境の悪性化におけるS100A8/A9の役割を解明し、S100A8/A9抗体治療薬の実用化に向けて研究を進める。

Outline of Final Research Achievements

S100A8/A9 (S100A8 and A9 heterodimer) is an inflammatory factor engaged in the onset of chronic inflammatory diseases. We analyzed patient plasma of several kinds of cancer and discovered excessive expression of S100A8/A9. Using RNA-seq analysis, we confirmed that stimulation of S100A8/A9 on macrophages induced upregulation of many types of cancer-associated cytokines and chemokines. Therefore, we have developed prominent new anti-human S100A8/A9 monoclonal antibody for treatment of cancer. We confirmed the therapeutic effect of our developed S100A8/A9 neutralizing antibody in subcutaneous pancreatic tumor mouse model. The antibody can terminate the negative spiral of aggravated inflammation induced by S100A8/A9, which in turn alleviates cancer progression.

Academic Significance and Societal Importance of the Research Achievements

開発した抗S100A8/A9抗体は、強力な抗炎症作用をもち、様々な炎症性疾患治療薬として実用化される可能性をもつ。先行してIPF(特発性肺線維症)およびIPF急性増悪について有意な治療効果を示し、ヒト化抗体を作製している。本研究成果により、RNA-seq解析の手法を用いて、S100A8/A9が炎症性疾患を増悪するメカニズムの一端が解明され、マウスモデルの実験データからがん転移治療薬としての開発抗体の可能性が示された。
