Background And Aims: Lipopolysaccharide (LPS) clearance is delayed in cholestatic liver diseases. While compromised clearance by Kupffer cells (KCs) is involved, the role of LPS uptake into hepatocytes and canalicular excretion remains unclear.
Approach And Results: Wild-type (WT) and bile salt export pump (Bsep) knockout (KO) mice were challenged i.
Background & Aims: 24-Norursodeoxycholic acid (NorUDCA) is a novel therapeutic bile acid used to treat immune-mediated cholestatic liver diseases, such as primary sclerosing cholangitis (PSC), where dysregulated T cells including CD8 T cells contribute to hepatobiliary immunopathology. We hypothesized that NorUDCA may directly modulate CD8 T cell function thus contributing to its therapeutic efficacy.
Methods: NorUDCA's immunomodulatory effects were first studied in Mdr2 mice, as a cholestatic model of PSC.
