| Outline of Final Research Achievements |
We tried to clarify the mechanisms by which high-fat diet results in life-style related diseases, especially we studied interactions between immune cells and metabolism cells as well as gut microbiota and enteral metabolites. We analyzed the effects of high-fat diet, reduction in adiponectin/AdipoR actions, AdipoR activation, and transplantation of gut microbiota from AdipoR deficient mice into germfree mice. Our results raised the possibility that reduction in AdipoR actions could result in increased inflammation and oxidative stress and so on, leading to dysregulation of gut microbiota and enteral metabolites, which could worsen fatty liver, NASH, atherosclerosis, conversely AdipoR activation could ameliorate them.
