Hormone-sensitive lipase is reduced in the adipose tissue of patients with type 2 diabetes mellitus: Influence of IL-6 infusion

Abstract

Aims/hypothesis: Type 2 diabetes mellitus is characterised by increased plasma NEFA and IL-6 concentrations, and IL-6 increases lipolysis in healthy men. We assessed the adipose tissue hormone-sensitive lipase (HSL) mRNA expression, protein expression and HSL activity in patients with type 2 diabetes mellitus, and determined the effect of IL-6 administration on these measures. Methods: Seven patients with type 2 diabetes mellitus (age 67±4 years, weight 87±7 kg) and six age- and weight-matched individuals visited the laboratory on two occasions. Subcutaneous adipose tissue biopsies and blood samples were obtained prior to and during 3 h of either saline or recombinant human IL-6 infusion. Re..
