Research Abstract |
Vitamin D receptor (VDR) responds to the active form of vitamin D3 and the bile acid lithocholic acid. We investigated the role of VDR in hepatic immune cells. VDR played a limited role in regulation of hepatic genes involved in metabolism and immunity in mice with cholestasis. Inflammatory responses were suppressed in the intestine of VDR-null mice. Increased NK cells and iNKT cells were observed in mononuclear cells from the liver of VDR-null mice. The results show a role of VDR in the intestine-liver pathway.
