中文摘要：

探究肉苁蓉低分子糖（LMSC）对RAW264.7小鼠巨噬细胞的激活作用靶点蛋白群及相关作用机制。该研究首先通过测定巨噬细胞吞噬活性以及NO释放量来评价LMSC对RAW264.7巨噬细胞的激活作用。实验结果显示,LMSC在0.25~2g·L^-1给药浓度可显著提高RAW264.7细胞的吞噬活性及NO的释放量,提示具有巨噬细胞激活作用。通过构建LMSC键合的环氧活化琼脂糖固相微球作为亲和介质,捕获RAW264.7细胞裂解液中特异性结合靶标蛋白;对高分辨质谱鉴定获得的LMSC靶标蛋白群进行信号通路富集分析,探讨LMSC巨噬细胞激活作用相关机制。实验共获得Eef2等24个LMSC靶点蛋白,分别涉及Fcγ受体依赖的吞噬、TNF-αNF-κB信号通路、糖酵解/糖原异生以及柠檬酸（TCA）循环和呼吸电子运输过程等10条巨噬细胞激活相关信号通路。以上结果提示LMSC通过作用于多个靶点进而调节细胞吞噬、NF-κB信号通路以及糖代谢途径最终实现对RAW264.7巨噬细胞激活作用。

英文摘要：

This study aims to investigate the targets and targets-involved mechanism for the macrophage activation of low molecular weight saccharides from Cistanche deserticola（ LMSC）. The phagocytic activity and NO release of RAW264. 7 cells were detected,and results showed that LMSC exerts immune activation effect by significantly increasing the phagocytic activity and NO release. LMSC-conjugated epoxy-activated sepharose beads were prepared as affinity reagent to capture the target proteins. Twenty-four proteins such as Eef2 were identified by LC-MS/MS analysis. Pathway enrichment analysis showed LMSC activated RAW264. 7 cells by regulating Fcgamma receptor dependent phagocytosis,TNF-alpha NF-κB signaling pathway,glycolysis/gluconeogenesis and the citric acid cycle and respiratory electron transport pathway.
