Helicobacter pylori have continued infection in the human stomach. It has been
confirmed that H. pylori can damage human gastric epithelial cells, cause oncogenesis
and suppress host’s immunity. In our previous studies, we found that H. pyori heat
shock protein 60 (HpHSP60) could induce macrophage to increase the high expression
of IL-10, TGF-β. Furthermore, HpHsp60 could induce the generation of regulatory T
cells (Treg cells). In addition, HpHsp60 also enhanced the abilities for migration of
tumor cell and angiogenesis. These indicate that HpHSP60 play an important role in
chronic infection of H. pylori and deterioration of H. pylori-induced gastric cancer. In
this project we will investigate how HpHSP60 regulate monocytes to produce
inflammatory and immunosuppressive cytokines, and the mechanism of how these two
kinds of cytokine influence each other. On the other hand, we will explore the
mechanism of how HpHSP60 promote gastric cancer cells in the molecular level.
The main purposes of this project are: (1) to explore the specific receptor for the
induction of iTreg cells and its downstream signaling pathway. (2) to study how
HpHSP60 stimulate human monocytes to produce inflammatory cytokine and
immunosuppressive cytokine. (3) to investigate the molecular mechanism of metastasis
of gastric cancer caused by HpHSP60. We hope the research can provide useful
information for the therapy of Helicobacter pylori-related diseases.
