Outline of Final Research Achievements

Gene expression of inflammatory cytokines increased with time in human coronary artery endothelial cells when they were stimulated with lipopolysaccharide, an endotoxin derived from periodontal pathogens. Similarly, gene expression of cardiac inflammatory cytokines increased significantly compared with the control in a model of bacteremia. However, the gene expression of inflammatory cytokines decreased significantly after 48 hours. Instead, the proportion of bone marrow-derived immune cells increased.
These findings suggest that periodontal pathogens cause inflammation in human coronary artery endothelial cells and cardiac tissue, and that bone marrow-derived immune cells may act to reduce the inflammation.
