Outline of Final Research Achievements

We found that CD4 T cells and CTLs decreased in tumor tissue, whereas NKT cells and MDSC cells increased in surrounding non-tumor tissue in the liver tumor mouse model induced by hydrodynamic injection of oncogene plasmids. We found that CTL and its surface PD-1 expressions increased in non-tumor tissues surrounding tumors. We found that HCC with CTNNB1 mutation showed lower levels of immune infiltration. Taken together, genetic mutation may affect immune system in the tumor microenvironment and thus might be involved in liver tumor development and progression.

Academic Significance and Societal Importance of the Research Achievements

本研究により様々な免疫学的解析が可能なマウスモデルの樹立に成功した。これにより今後の癌免疫研究並びに様々な治療薬の免疫動態が評価可能なプレクリニカルモデルとしての有用性が期待される。また、臨床試料の解析からゲノム異常と免疫動態に関係があることを見出した。このことから、癌ゲノム以上を同定することで、患者予後の層別化や、免疫修飾を主眼とした薬剤の治療効果予測バイオマーカーの開発につながる研究成果であり、社会的意義は大きいと考える。
