摘要: 三七总皂苷(Panax notoginseng saponins,PNS)是从五加科人参属植物三七根部提取的有效活性成分,临床广泛应用于动脉粥样硬化疾病的治疗,但其相关机制尚不完全清楚,本课题对ApoE基因敲除(ApoE-/-)小鼠的体内实验研究发现PNS具有明显的改善血脂的功能,并对小鼠动脉粥样硬化斑块的形成具有抑制作用,其分子机制与TLR4/SYK信号通路相关;进一步通过体外细胞实验发现PNS能够抑制小鼠斑块内巨噬细胞的吞噬能力和CD36的表达,从而抑制泡沫细胞的形成。因此我们认为三七总皂苷可通过调节TLR4/SYK信号抑制ApoE-/-小鼠泡沫细胞的形成从而抑制动脉粥样硬化的进展。

Abstract:

Panax notoginseng saponins (PNS) is an active ingredient extracted from the roots of Panax notoginseng,which is widely used in the treatment of atherosclerotic diseases.However,its related mechanism is not completely clear.In this study,we found that PNS has the function of improving blood lipid and inhibiting the formation of atherosclerotic plaque in ApoE-/- mice.Its molecular mechanism is related to TLR4/SYK signaling pathway.Furthermore,in vitro cell experiments showed that PNS could inhibit macrophage phagocytosis and CD36 expression in mouse plaques.Therefore,we believe that PNS can inhibit the formation of foam cells in ApoE-/- mice by inhibiting TLR4/SYK signaling so as to inhibiting the progression of atherosclerosis.
