| Research Abstract |
This study revealed that cellular senescence is involved in the pathogenesis of liver diseases such as primary biliary cirrhosis(PBC). Senescent biliary epithelial cells in inflamed and damaged small bile ducts in PBC show increased expression of chemokines such as CCR2 and CX3CL1. Cultured senescent biliary epithelial cells showed increased expression of various chemokines and induced migration of monocytes and hepatic stellate cells in co-culture. These findings suggests that senescent biliary epithelial cells may play a role in augmentation of inflammation around bile ducts by regulating microenvironment in PBC.
