摘要: 目的 探讨人参、乳双歧杆菌BL-99及其组合物在长春瑞滨(VNR)诱导免疫抑制状态下对巨噬细胞免疫功能的调节作用,并初步分析其作用机制。方法 用长春瑞滨构建低免疫力斑马鱼模型和小鼠巨噬细胞系(RAW264.7)模型。斑马鱼实验中,用转基因荧光斑马鱼观察巨噬细胞数量与吞噬功能的变化。细胞实验中,CCK-8法检测人参、BL-99及其组合物对RAW264.7细胞活力的影响、中性红法检测吞噬功能、DCFH-DA荧光探针法检测细胞内活性氧(ROS)水平、annexin V/PI双染检测凋亡情况及RT-qPCR检测凋亡与吞噬相关基因(Bcl2、caspase3、Msr1、Rac1)表达;同时结合网络药理学预测人参的作用机制。结果 与对照组相比,模型组斑马鱼巨噬细胞数量和吞噬功能显著下降(P<0.001)。与模型组相比,人参与BL-99单独干预均显著提高巨噬细胞数量并增强了吞噬功能(P<0.001);联合干预组的效果显著优于单药组(P<0.05)。在RAW264.7细胞实验中,人参、BL-99及联合干预组细胞活力与吞噬功能均显著提高,活性氧水平及凋亡率显著下降(P<0.01)。RT-qPCR结果显示,人参与BL-99组合可上调Bcl2、Msr1和Rac1表达,下调caspase3表达(P<0.01)。网络药理分析表明,人参调控低免疫力巨噬细胞功能可能与抗凋亡通路相关。结论 人参和乳双歧杆菌BL-99在长春瑞滨诱导的免疫抑制模型中通过减轻氧化应激、调控凋亡及吞噬相关基因表达,协同增强了巨噬细胞免疫功能。

Abstract: Objective To investigate the modulatory effects of ginseng, Bifidobacterium lactis BL-99 and their combination on the immune function of macrophages under vinorelbine(VNR)-induced immunosuppression, and to preliminarily explore the underlying mechanisms. Methods Vinorelbine-induced immunosuppressive models were establi-shed in both zebrafish and the murine macrophage cell line RAW264.7. In zebrafish experiments, changes of macrophage number and phagocytic function were observed using transgenic fluorescent zebrafish. In cell experiments, the following assessments were conducted: RAW264.7 cell viability by CCK-8 assay, phagocytic function by neutral red assay, intracellular reactive oxygen species (ROS) levels by DCFH-DA fluorescence probe assay, apoptosis by annexin V/PI double staining, and the expression of apoptosis- and phagocytosis-related genes (Bcl2, caspase3,Msr1, Rac1) by RT-qPCR. Network pharmacology was used to predict the mechanism of ginseng. Results Compared to the control group, the model group showed a significant reduction in macrophage number and phagocyte function (P<0.001). Both ginseng and BL-99 monotherapies significantly increased the number of macrophages and enhanced phagocytosis (P<0.001), with the combined intervention group showing stronger effects(P<0.05). In RAW264.7 cells, compared with the model group, cell viability and phagocytosis were significantly enhanced, reactive oxygen species levels and apoptosis rate was significantly decreased in the ginseng, BL-99 and their combination group(P<0.01). RT-qPCR results showed that ginseng in combination with BL-99 upregulated the expression of Bcl2, Msr1 and Rac1 and downregulated the expression of caspase3(P<0.01). Network pharmacological analysis suggested that the modulatory effect of ginseng on macrophage function under immunosuppressive conditions is closely associated with anti-apoptotic signaling pathways. Conclusions Ginseng and Bifidobacterium lactis BL-99 synergistically enhance macrophage immune function in the vinorelbine-induced immunosuppression model by alleviating oxidative stress and regulating the expression of apoptosis- and phagocytosis-related genes.
