Differential regulation of hepatic organic cation transporter 1, organic anion-transporting polypeptide 1a4, bile-salt export pump, and multidrug resistance-associated protein 2 transporter expression in lymphocyte-deficient mice associates with interleukin-6 production.

Cholestasis results from interrupted bile flow and is associated with immune-mediated liver diseases. It is unclear how inflammation contributes to cholestasis. The aim of this study was to determine whether T and B cells contribute to hepatic transporter expression under basal and inflammatory conditions.
