Visfatin is a novel adipokine which was discovered in 2005 by Fukuhara. Visfatin is highly enriched in the visceral fat of humans and mice with obesity, which was previously called pre-B-cell colony-enhancing factor, and exhibits nicotinamide phosphoribosyl transferase enzymatic activity. Visfatin regulates insulin secretion in pancreatic β cells. Visfatin is not only an adipocyte-specific protein, and it has a close relation with non-alcoholic fatty liver disease (NAFLD). Zinc-α2-glycoprotein (ZAG), which is identical to the previously named lipid-mobilising factor, is a single-chain polypeptide. It is secreted by both brown and white adipocytes. ZAG possibly functions as a novel protein factor responsible for the decomposition of tissue lipids. ZAG also has a close relationship with NAFLD. This paper will review the advances in understanding the role of visfatin and ZAG in the pathogenesis of NAFLD.
