| Outline of Final Research Achievements |
Resveratrol is a phytoalexin polyphenolic compound present in various plants, including grapes and peanuts. Multiple lines of evidence suggest that resveratrol has beneficial effects on human health. Liver macrophages, or Kupffer cells, are suggested to be one of the major immune effectors in the pathogenesis of steatohepatitis. However, the mechanisms underlying increased lipid content in the steatohepatitic liver and the involvement of Kupffer cells are still poorly understood. We hypothesized that certain liver proteins modulated by resveratrolmight interact with Kupffer cells, and investigated the target protein underlying the ability of resveratrol to improve fatty liver. Our results provide evidence that resveratrol increases the number of CD68+ Kupffer cells in the liver and it may be involved in reduction of LDs. Our findings provide new insight into the beneficial effects of resveratrol on hepatic lipid metabolism in the context of the modulation of Kupffer cell function.
