Outline of Final Research Achievements |
In this study we performed the following studies, to develop a more comprehends understanding of mechanisms underlying persistent inflammation in Helicobacter pylori-infected gastric mucosa, and to try to apply the outcome to vaccine development. (1) Control mechanisms of gastric responses: we have discovered a novel mechanism to regulate adherence function of bacterial adhesin BabA during persistent infection. (2) Control mechanisms of intestinal Peyer’s patches: we comprehensively analyzed outer membrane protein profiles of H. pylori under anaerobic conditions, and identified candidate factors for the interaction of bacteria with antigen presenting cells. (3) Vaccine: we analyzed prophylactic vaccine effect of anaerobic cultured bacteria for H. pylori infection using a Mongolian gerbil animal model of H. pylori infection.
