Adipocytes express angiotensin II (AngII) receptors; however the direct effects of AngII at the adipocyte remain unclear. Knockout mouse models of renin-angiotensin system components exhibit reduced body weight, reduced adiposity, improved glucose tolerance, and improved blood pressure when fed high fat diets, which may be due to reduced action of AngII through the AT1aR in adipocytes. Additionally, hypercholesterolemic AT1aR deficient mice are protected from AngII-induced increases in atherosclerosis and abdominal aortic aneurysm (AAA) formation. We hypothesized that deficiency of AT1aR in adipocytes would reduce the development of obesity, obesity-induced disorders, and vascular diseases. To test this hypothesis, we created a …
