FGF21 and Hepatic steatosis: However, adipokines (adiponectin, leptin) are thought to contribute to the anti-inflammatory effects of various hepatokines, such as apelin, adropin and fetuin-A by decreasing the local production of IL-6 and fibroblast growth factor 21 (FGF21), which prevent hepatic steatosis and fibrosis [95,96,97,98,99].
