Outline of Final Research Achievements

The xenobiotic-sensing nuclear receptor PXR is well-known to play important roles in drug/xenobiotic clearance and hepatic energy metabolism. Recent studies have revealed that PXR also has a role in the regulation of immune/inflammatory responses. However, the precise details are still not fully understood. In this study, we have investigated the molecular mechanism underlying PXR-mediated regulation of immune/inflammatory responses using an in vivo mouse model of immune-mediated liver injury and in vitro cell-based experimental models. Our findings will provide us with useful information to investigate how PXR immune/inflammatory responses.
