Potential mechanisms by which statins may favorably affect liver histology in NASH/NAFLD. This cartoon emphasizes the pleiotropic effects of statins on the liver and the potential mechanisms that may combine to ameliorate the primary pathological conditions of NASH/NAFLD, such as steatosis, inflammation, and fibrosis. The downward pointing arrow signifies downregulation.
