Research Abstract

The aim of this study was to obtain a comprehensive understanding of the mechanisms underlying Helicobacter pylori-induced inflammation. We focused on three aspects of the interplay between H. pylori and the host : macroscopic, macrophages and dendritic cells, and peyer's patch analyses. As a result, we found that H. pylori modulates both bacteria and host adherence factors during the course of infection in vivo.
