Context: Dipeptidyl-peptidase-IV (DPP-4) inhibition increases endogenous GLP-1 activity, resulting in improved glycemic control in patients with type 2 diabetes mellitus. The metabolic response may be explained in part by extrapancreatic mechanisms.
Objective: We tested the hypothesis that DPP-4 inhibition with vildagliptin elicits changes in adipose tissue and skeletal muscle metabolism.
