Mesenteric Fat Lipolysis Mediates Obesity-Associated Hepatic Steatosis and Insulin Resistance

Hepatic steatosis and insulin resistance are among the most prevalent metabolic disorders and are tightly associated with obesity and type 2 diabetes. However, the underlying mechanisms linking obesity to hepatic lipid accumulation and insulin resistance are incompletely understood. Glycoprotein 130 (gp130) is the common signal transducer of all interleukin 6 (IL-6) cytokines. We provide evidence that gp130-mediated adipose tissue lipolysis...
