Bushenkangshuai tablet reduces atherosclerotic lesion by improving blood lipids metabolism and inhibiting inflammatory response via TLR4 and NF- B signaling pathway

Abstract

Bushenkangshuai tablet (BSKS) is a Chinese herbal compound which has been used for the treatment of cardiovascular and cerebrovascular diseases in China for decades. This study intends to explore the molecular mechanism of BSKS against atherosclerosis in ApoE-/- mice. ApoE-/- mice were fed with western-type diet for 6 weeks and then were given BSKS for 6 weeks. The results showed that BSKS attenuated the size of the atherosclerotic lesion, reduced visceral adipose content, and decreased blood lipids. We also found that BSKS promoted the expression of adiponectin and its receptors, inhibited the expression of Toll-like receptor 4 and nuclear factor-kappa B, decreased the levels of interleukin-1 beta, monocyte chemotactic protein-1, and vascular cell adhesion molecule-1, and increased the levels of interleukin-10 and adiponectin. Our data provided evidence that BSKS exerted an antiatherosclerotic effect by lowering blood lipids and inhibiting inflammatory response via TLR4 and NF-B signaling pathway.
