| Outline of Final Research Achievements |
Oral infection of the periodontopathic bacteria P. ginigivalis (P. g.) activate various inflammasomes and induce inflammatory cytokine production, resulting in the production of Th17 cells It was suggested that chronic inflammation may persist due to induction and enhancement of IL-17. Furthermore, it was suggested that gingipain and fimbria, which are the pathogenic factors of P. g., are involved in the activation of these inflammasomes. P. g. or A. a. infection into ApoEshl mice also increased the oxidative denaturation enhancing action of LDL. In vitro experiments, P. g. and P. g. LPS enhanced active oxygen (ROS) production from vascular endothelial cells. Furthermore, it was suggested that P.g. has a common epitope with ox-LDL and may be involved not only in direct oxidation by P.g. but also in inflammation enhancement due to molecular homology.
