Outline of Final Research Achievements |
Significantly fewer tumor-infiltrating lymphocytes were found in Fusobacterium nucleatum-positive esophageal cancer cases, suggesting that Fuso may contribute to tumor immunosuppression. The results of this study were published in the British Journal of Cancer. To further elucidate the mechanism by which Fuso influences tumor immunity, they performed co-culture experiments with cancer cell lines. They found that Fuso activates the NFKB pathway via the nuclear receptor NOD 1, leading to the malignant gain of cancer cells. The results were reported in Cancer letters.

Academic Significance and Societal Importance of the Research Achievements |
Microbiomeは、近年、癌、肥満、炎症性腸疾患など様々な疾患との関連が報告され、注目を集めている先端性の高い分野である。また、免疫チェックポイント阻害剤の登場により腫瘍免疫の理解はますます重要となっており、さらに癌におけるmicrobiomeは癌治療・癌化学予防のtargetとして注目を集めていることからも、この研究による成果はtranslational researchとして臨床に直結する意義深いものになると考えられる。
