About this trial

The investigators will test the hypothesis that, in adults with type 1 diabetes (T1D), glucagon-like peptide-1 receptor agonism (GLP-1RA, i.e. dulaglutide) enhances insulin-mediated skeletal muscle microvascular perfusion via attenuating endothelial oxidative stress and thereby improving endothelial function.
