Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <sec> <title>Objective—</title> <p>The purpose of this study was to determine the role of the endothelial glucocorticoid receptor in the pathogenesis of atherosclerosis.</p> </sec> <sec> <title>Approach and Results—</title> <p>Control mice and mice lacking the endothelial glucocorticoid receptor were bred onto an <italic>Apoe</italic> knockout background and subjected to high-fat diet feeding for 12 weeks. Assessment of body weight and total cholesterol and triglycerides before and after the diet revealed no differences between the 2 groups of mice. However, mice lacking the endothelial glucocorticoid receptor developed more severe atherosclerotic lesions in the aorta, brachiocephalic artery, and aortic sinus, as well as a heightened inflammatory milieu as evidenced by increased macrophage recruitment in the lesions.</p> </sec> <sec> <title>Conclusions—</title> <p>These data suggest that the endothelial glucocorticoid receptor is important for tonic inhibition of inflammation and limitation of atherosclerosis progression in this model.</p> </sec> </abstract>
