Outline of Final Research Achievements

Although the efficacy of vaccines against an infectious disease, periodontitis, has been suggested, it has not been applied in clinical practices. In this study, we examined the possibility of development of a vaccine to prevent/treat periodontitis focusing on induction of secretory IgA production via modulation of mucosal immunity. We found that, chemokine production and follicular T cell activation were induced by imidazoquinoline derivatives which are nucleic acid antigen - like compounds, and secretory IgA production was promoted. These findings suggested the possibility of developing a periodontitis vaccine using nucleic acid antigen as an adjuvant.
