| Outline of Final Research Achievements |
Periodontitis is a leading cause of tooth loss that is associated with a periodontal pathogenic bacterium. It has been reported that the pathogenesis of periodontitis is mediated by host immune response, especially IL-17A-producing helper T cells, Th17 cells. However, the regulatory mechanism to induce the immune response via Th17 cells by periodontal pathogens remains to be elucidated. In this study, we found that immunological network between oral cavity and intestinal tract is important for the development of periodontitis.

| Academic Significance and Societal Importance of the Research Achievements |
従来の歯周病の治療・予防は、口腔内の歯垢や歯石の除去を主体としたのもであった。本研究で得られた成果により、歯周病発症を制御する腸内細菌や歯周病の病態形成に関わるTh17細胞を標的とした治療法や予防法が可能になる。このように歯周病に対する新しい治療法や予防法の開発への基盤を構築することができた。
