Western Diet (WD)-fed Apoe−/− rats exhibit small fatty streak lesions of atherosclerosis limited to the aortic sinus. (A) Histological slides of the aortic sinus in an Apoe−/− rat fed the LF diet without detectable plaque (40X, Stained with Oil Red O), and Apoe−/− rat fed the WD with an early fatty streak-type lesion (40X, Stained with Oil Red O). (B) Higher magnification of the fatty streak lesion in A. The lesion is indicated by an arrow. (C) Graphical representation of the lesion area measurements at 20 weeks of age showed significantly higher plaque burden in animals fed Western diets (groups 3 and 4) compared with animals fed the low fat control diet. Data are expressed as mean ± SEM. n = 14 in the low fat (LF) and low fat + gluten (LF + G) groups, n = 11 in the Western Diet (WD) group and n = 7 in the Western Diet + gluten (WD + G) group.
