Summary
AIM2: The purpose of Aim-2 of this study is to determine the role of basal GLP-1 action on the beta-cell response to insulin resistance. Healthy subjects will have fasting GLP-1 action determined with GLP-1r blockade before and after induction of experimental insulin resistance. The investigators hypothesize that fasting GLP-1 action will increase to compensate for experimental insulin resistance. AIM3: The purpose of Aim-3 of this study is to determine the role of basal GLP-1 action on fasting glucose regulation in lean, obese, pre-diabetic and type 2 diabetic (T2DM) subjects. A cross sectional study of age-matched subjects across the spectrum of glucose tolerance will be used to test the hypothesis that fasting GLP-1 action increases as beta-cell function declines.
