Zusammenfassung
Nonalcoholic steatohepatitis involves necroinflammatory activity and fibrosis, which are believed to be mediated by lipotoxicity caused by toxic metabolites from excess fatty acids. Epidemiological studies indicate that age has impact on the natural course of NAFLD. The aim of this study was to assess whether there are age dependent differences in the susceptibility to lipotoxicity and NASH in primary hepatocytes and a dietary murine model, respectively. Methods and Results: Upon stimulation with free fatty acids hepatocytes isolated from 4 week old mice revealed a significantly higher intracellular lipid accumu…
