Outline of Research at the Start

歯周病と全身疾患の関連研究において,歯周病原細菌と消化管がんの因果関係が示唆されているがその詳細は不明である。本研究においては,腸管サンプルと口腔サンプルを用いた網羅的解析と動物実験により,消化管の発がん関連口腔細菌の同定とその分子メカニズムを検討する.それらが明らかになることで,口腔マイクロバイオームを基軸とした消化管がん全般における先制医療プラットフォームの構築が期待される.

Outline of Final Research Achievements

Previous oral-gut association studies have suggested an association between periodontopathogenic bacteria and colorectal cancer. We performed microbiome analysis of clinical specimens from polyp patients for exploring oral-derived pathogenic pathobiont. Our results did not reveal any bacteria characteristic of colorectal cancer, but suggested that many oral bacteria are present in the intestinal tract and may affect the bacterial flora of the intestinal mucosal surface.

Academic Significance and Societal Importance of the Research Achievements

日本人ポリープ患者の腸管に口腔由来の細菌が存在している可能性が確認され,これまでの歯周病と下部消化管疾患の関連報告も踏まえ,口腔環境を保つことの重要性が示唆される.また口腔細菌をターゲットにしたプロバイオティクス療法や特異的抗菌療法による,下部消化器疾患の早期予防・先制医療としての将来性が期待される.
