Our results indicate that ALF increases BBB permeability to cyclosporin A by lowering the function of P-glycoprotein and tight junctions, consequently leading to augmentation of cyclosporin A-induced neurotoxicity. The possibility that cyclosporin A increases the risk of neurotoxicity including tremors at an early phase of liver transplantation must be considered.
