Abstract
BACKGROUND
Nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes (T2D) are growing public health problems, and are strongly associated. The link between the two conditions remains poorly understood. Hepatic interleukin-6 (IL-6), a major proinflammatory cytokine, expression is increased in animal models of NAFLD, while in mice, selective sustained upregulation of IL-6 in the liver results in systemic insulin resistance. The extent and clinical significance of hepatic IL-6 expression in human NAFLD, as well as potential mechanisms by which steatosis may increase IL-6 production in the liver, have not been examined.
AIMS
To ascertain the occurrence and significance of IL-6 expression in the liver in human NAFLD.
