KeywordsNASH / 大腸癌 / 間葉系幹細胞 / 非アルコール性脂肪肝炎 / 腸管免疫 / 消化管免疫
Outline of Research at the Start

本研究は①非アルコール性脂肪肝炎(NASH)における腸管の免疫細胞群と癌微小環境の動態の解明。②NASHの肝臓における脂肪沈着、炎症および線維化と代謝産生物質が腸管に与える影響の解明。これによりNASHが大腸癌の発生と進展に与える影響の詳細を明らかとすることを目的とする。
NASHにおける腸管と肝臓の相互連関において腸内細菌や粘膜由来の代謝物質が肝臓に与える影響についての検討は近年発展を認める。しかし、NASHにおける腸管の免疫動態と癌微小環境の詳細解明はなされておらず,肝臓の病態が腸管の免疫細胞を介し大腸癌へ与える影響の解析により,NASHを背景とした大腸癌に対する新しい予防法確立につながる。

Outline of Final Research Achievements

Non-alcoholic steatohepatitis (NASH) is on the rise due to changes in lifestyle, and it's also been linked to an increased risk of colorectal cancer. While the impacts of NASH on the immune cells and the cancer microenvironmenthasn't been fully understood.
To investigate, we conducted a study using C57BL/6 mice and NASH mice to create a syngeneic colon cancer mode and examined differences in tumor development and progression. Additionally, we analyzed immune cell fractions and localization, as well as gene expression in the intestinal tract and tumor tissues using techniques like immunohistochemical staining (IHC), flow cytometry (FCM), and DNA microarray.
Our findings revealed increased numbers of T cells, granulocytes, and macrophages in the intestinal tissues of NASH mice compared to wild type mice. This suggests that altered immune dynamics in the intestinal tract of NASH mice may contribute to the heightened colorectal carcinogenesis observed.

Academic Significance and Societal Importance of the Research Achievements

NASHマウスの腸管に移植した大腸癌細胞株はwildマウスへの移植と比較し、腫瘍径および腫瘍重量の有意な増大を認め、NASHマウスの腸管組織においてT細胞、顆粒球、マクロファージの増加を認めた。NASHマウスの腸管では大腸癌がより進展し、これには腸管における免疫動態の変化が寄与する可能性が示唆された。本研究成果であるNASHにおける腸管の免疫動態と大腸癌に与える影響の解明は,NASH患者の増加に伴い増加が予測される大腸癌に対する新たな予防法確立の基盤を創造しうる重要な社会的意義を持つ。
