摘要: 目的:探讨参芪扶正注射液(Shenqi fuzheng injection, SFI)干预肿瘤免疫作用及初步分子机制研究。方法:采用B16-PKM2-OE建立低糖肿瘤微环境动物模型;采用ELISA试剂盒检测白细胞介素-2(IL-2),干扰素-γ(IFN-γ),CD40L和转化生长因子-β1(TGF-β1)的水平;采用Western blot法检测CD4+T细胞葡萄糖转运蛋白(Glut-1)和糖酵解关键酶(HK、PFK和PK)的表达。结果:试剂盒检测结果显示,SFI可以提高肿瘤组织中IL-2、IFN-γ、CD40L水平,降低TGF-β1的水平。Western blot法检测结果发现,SFI能够促进CD4+T细胞细胞膜表面Glut-1蛋白的表达,同时呈剂量依赖性上调糖酵解关键酶的表达。 结论:SFI能够升高肿瘤组织中的IL-2、IFN-γ和CD40L水平并降低TGF-β1水平,同时增加肿瘤组织里活化CD4+ T细胞的数量,促进CD4+T细胞的糖酵解,表明SFI能够改善肿瘤免疫微环境。

Abstract: AIM: To investigate the effect of Shenqi fuzheng injection (SFI) on tumor immunity and its preliminary molecular mechanism. METHODS: The animal model of low glucose tumor microenvironment was established by B16-PKM2-OE; the level of interleukin-2(IL-2) and interferon-γ(IFN-γ), CD40L and transforming growth factor-β1(TGF-β1) were detected by ELISA kit; the expressions of glucose transporter-1 (Glut-1) and key enzymes of glycolysis ( HK, PFK and PK ) in CD4+T cells were detected by Western blot. RESULTS: The results of the kit showed that SFI could increase IL-2, IFN-γ and CD40L, and decreased TGF-β1 in tumor tissues. Western blot assay showed that SFI could promote the expression of Glut-1 protein on the surface of CD4+T cell membrane, and up-regulated the expression of key enzymes of glycolysis (HK, PFK1 and PK) in a dose-dependent manner. CONCLUSION: SFI can increase the expression levels of IL-2, IFN-γ, CD40L and decrease the expression level of TGF-β1 in tumor tissues. Also, it increases the number of activated CD4+T cells in tumor tissue and promotes the glycolysis of CD4+T cells, indicating that SFI can improve the tumor immune microenvironment.
