| Outline of Final Research Achievements |
The role of Interleukin (IL)-35 in periodontitis is not clear and the effect of IL-35 on the function of T helper 17 (Th17) cells is still incompletely understood. Therefore, we investigated the effects of IL-35, undertaken to compare experimental periodontitis induced by Porphyromonas gingivalis, clearly associated with the pathogenesis of periodontitis in Ebi3 knockout (KO) mice and wild-type (WT) mice. Computed tomography(CT) analysis and hematoxylin-and-eosin (H&E) and tartrate-resistant acid phosphatase (TRAP) staining were performed. Alveolar bone resorption was seen around the first and second mandibular molars in P.gingivalis-infected WT mice or in infected KO mice. Furthermore, infected Ebi3 KO mice alveolar bone resorption fenestration was higher than any other groups. Histological analysis of mandibles from Ebi3 KO and WT mice did not show clearly difference in the elements characteristic of periodontal tissues.
