| Outline of Final Research Achievements |
We focused on oral bacteria as one of the candidates of risk factors for atherosclerosis. The capability of invasion of human aortic endothelial cells (HAEC) by oral bacteria derived from human and the subsequent expression of pattern-recognition receptors and production of cytokines (IL-6, IL-8, MCP-1) by viable invaded HAEC were examined to understand the induction mechanism of atherosclerosis by oral bacteria.
Oral bacteria derived from human were capable of invading HAEC. The expression of pattern-recognition receptors and cytokines in HAEC invaded by oral bacteria increased markedly compared with those in non-invaded HAEC. These results suggested that inflammatory reactions in HAEC induced by invasive oral bacteria might be causative to induce atherosclerosis in human.
