“…However, adenovirus 36 (Ad36)-induced obesity in mice increases angiogenesis in adipose tissue and improves glycemic control, regardless of increased adiposity and inflammation [ 7 ]. Hepatitis C virus (HCV) infection is associated with obesity, diabetes, and nonalcoholic fatty liver disease and increases the risk of progression to hepatic fibrosis [ 8 , 9 ]. HCV directly causes insulin resistance independent of the visceral adipose tissue area in non-obese and non-diabetic humans [ 10 ].…”

Viperin is an interferon-inducible antiviral protein, responsible for antiviral response to a variety of viral infections. Here, we show that silencing viperin by antisense oligonucleotides (ASO) protects against diet-induced glucose intolerance, and yet exacerbates adipose tissue inflammation. In high-fat diet-fed mice, viperin ASO improves glucose homeostasis, reduces plasma triglyceride concentrations and ameliorates diet-induced hepatic steatosis. Peripheral delivery of viperin by adeno-associated virus elevates fasting plasma glucose and insulin concentrations and reduces insulin-stimulated glucose uptake in skeletal muscle. Viperin overexpression reduces epinephrine- stimulated lipolysis in white adipose tissue, whereas viperin ASO increases expression of lipolytic genes. Targeting viperin by antisense oligonucleotides promotes reciprocal regulation of hepatic and adipose lipogenesis by reducing hepatic lipid content and increasing triacylglycerol content in adipose tissue. These findings reveal viperin as an important target to improve glucose metabolism, and suggest that suppressing antiviral potential may improve the metabolic adaptability to high-fat diet.
