| Research Abstract |
Streptococcus mutans, a major pathogen of dental caries, is known to invade the bloodstream and sometimes causes systemic diseases. The present study investigated the possible mechanism of aggravation of inflammatory bowel diseases caused by S. mutans. We found that hepatocytes invaded by S. mutans produced IFN-gamma, while alpha-AGP and amyloid A1 enhanced inflammation and unbalanced the immune system, leading to aggravation of inflammatory bowel diseases. In addition, it was shown that the neutralizing antibody against IFN-gamma improved the condition.
