| Outline of Final Research Achievements |
Mouse liver Kupffer cells are classified into two subsets, recruiting CD11b(+) cells with potent cytokine producing capacity and resident CD68(+) cells with strong phagocytic activity. The former population induces hepatocyte apoptosis in experimental hepatitis models. On the contrary, these cells accelerate hepatocyte regeneration after partial hepatectomy. In Non-Alcoholic Steatohepatitis model, this cell population is strongly activated and induces chronic hepatocyte injury which in turn induces hepatic fibrosis and cirrhosis. On the other hand, the latter population expresses PPAR-γ and LXR which are indispensable in glucose and cholesterol metabolism. This result suggests the cell population exerts significant role in energy metabolism.
