Electronic Thesis and Dissertation Repository
Pre-diabetes is associated with impairments in cardiovascular health that manifest prior to the onset of overt type 2 diabetes. Characterized by hyperinsulinemia and insulin resistance, pre-diabetes has been associated with increases in sympathetic nerve activity, which may result in augmented sympathetic control of the peripheral vasculature within skeletal muscle. Currently however, there are no studies investigating the impact of pre-diabetes on sympathetically-mediated vascular control. The primary study of this thesis investigated the effects of pre-diabetes on baseline sympathetic neuropeptide Y Y1 receptor (NPY Y1R) and alpha 1 adrenergic receptor (a1R) control of hindlimb vascular tone. Experiments were carried out in …
