| Outline of Final Research Achievements |
We elucidated the enterocolitis induction mechanism that a chronic periodontal disease induced using the periodontal disease model mouse which applicants established before in this study. We produced the model mouse using Fusobacterium nucleatum (F.nucleatum). And we used this model mouse to elucidate it how immune cells involved in homeostasis using this acted on organs between oral cavity and intestinal tract.
As a result, the decrease in significantly different alveolar bone loss occurred, and the destruction image of the alveolar bone with the lymphocytic infiltration was present in morphology observation. Also, inflammatory cell infiltration was present in lamina propria of small intestine and the large intestine in morphology observation. In addition, we analyzed immune cells by the flow cytometry. As a result, murine periodontal tissues and the intestinal tissue which infected with F.nucleatum, we confirmed that the frequency of a macrophage and dendritic cells increased.
