Outline of Final Research Achievements |
Helicobacter cinaedi is the most common enterohepatic Helicobacter species that causes bacteremia in humans, but its pathogenicity is unclear. Here, we investigated to clarify the mechanism of pathogenesis in emerging infections by H. cineadi. We found that H. cinaedi persistently latent in the bone marrow in infected mice and enhance the pathogenesis of atherosclerosis. We also found that this bacterium parasitize intracellularly by avoiding from autophagic killing and hijacking of reactive persulfide-driven energy metabolism of mitochondria. These data provide the important findings for the elucidation of the theory of H. cinaedi infectious disease such as arteriosclerotic pathogenesis and the development of preventive / therapeutic methods.
