Proinflammatory Endothelial Activation Detected by Molecular Imaging in Obese Nonhuman Primates Coincides With Onset of Insulin Resistance and Progressively Increases With Duration of Insulin Resistance

Abstract

In primates with diet-induced obesity, endothelial inflammatory activation is an early event that occurs coincident with the development of IR and long before any measurable change in carotid intima-media thickness. Endothelial activation is related more to the duration rather than to the severity of IR and is not mirrored by changes in plasma biomarkers.
