ABSTRACT

Although hereditary or acquired defects in hepatobiliary transporter systems cause or predispose to cholestasis, adaptive bile acid transporter changes can counteract cholestasis by reducing hepatocellular and systemic concentrations of retained cholephiles. An important level in the regulation of adaptive bile acid transporters and overflow pathways is mediated at the transcriptional level by nuclear hormone receptors. Moreover, therapeutic approaches targeting nuclear receptors in cholestasis may stimulate these adaptive changes and open a new perspective for the treatment of cholestatic liver diseases. This review gives a comprehensive overview on bile acid transporters in the enterohepatic circulation and their adaptive changes in response to cholestasis as well as the regulatory networks underlying these adaptive mechanisms.
