  ABSTRACT: Background: Studies demonstrated the autoantiboies against angiotension II type 1 receptor (AT1-AAs) could induce vascular endothelial dysfunction. Our objective is to investigate the effect of AT1-AAs on atherosclerosis. Methods: AT1-AAs were purified from sera of patients with primary hypertension. Thirty-six New Zealand white rabbits were underwent balloon-induced abdominal aortic endothelial injury and fed an atherogenic diet for 6 weeks and were randomly divided into six groups with different drugs for 4 weeks. The levels of AT1-AAs, tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in different stage were detected by ELISA. The abdominal aortas of rabbits were stained with hematoxylin and eosin. The expression of matrix metalloproteinases-2 (MMP-2) in aortic tissue was detected by Western blotting. Results: The levels of TNF-α in the eighth week (0.17 ± 0.04, 0.34 ± 0.08) and in the tenth week (0.23 ± 0.04, 0.54 ± 0.11) were significantly higher than that at the beginning of test (0.04 ± 0.03, 0.08 ± 0.02) in the group of AT1-AAs with low-dose and high-dose (P Conclusion: The results showed that the AT1-AAs could aggravate the inflammatory reaction and the plaque formation.
