ABSTRACT
ObjectiveTo observe the effects of telmisartan on toll-like receptor (TLR) 4 expression in monocytes of mice atherosclerosis (AS)model, and explore the mechanism of inflammation.MethodsAS mice model were established in ApoE-deficient mice fed with high-fat diet,and treated with telmisartan as intervention group. After 8 weeks, serum low density lipoprotein,triacylglycerol and total cholesterol were detected in group fed with high-fat diet and intervention group.TLR 4 expressions in two groups were analyzed by flow cytometry. Results There was no significant difference in levels of blood lipids between the two groups.TLR4 expression in monocytes in telmisartan intervention group was lower than group fed with high-fat diet (P＜0.05).ConclusionsTelmisartan may intervene the inflammation during atherosclerosis by downregulating TLR4 expression in monocytes.
