HSD11B1 and Hepatic fibrosis: We have used the reversible carbon tetrachloride‐induced model of hepatocyte injury and liver fibrosis to show that in two models of genetic 11βHSD1 deficiency (global, Hsd11b1–/–, and hepatic myofibroblast‐specific, Hsd11b1fl/fl/Pdgfrb‐cre) 11βHSD1 pharmacological inhibition in vivo exacerbates hepatic myofibroblast activation and liver fibrosis.
