Outline of Final Research Achievements	It is a well-known that H. pylori infection causes stomach cancer. On the other hand, H. pylori that can not infect C57BL / 6 mice, which is the source of genetically modified mice. This was a obstacle in mouse experiments. Recently it has been reported that PMSS 1 strain can infect. We confirmed that the PMSS 1 strain can infect B6 mice. Then we made the gastritis mice model by useing PMSS1 strain and we reported a paper that IL - 1 signal and SOX 9 are involved in intestinal metaplasia. Subsequently, PMSS 1 strain did not express Cre, but we make CagA of PMSS1 to be KO and we confirmed activation of stress MAPK was dependent on CagA.
