中文摘要: 肿瘤免疫抑制微环境(TIME)在肿瘤生长和免疫逃逸中扮演着至关重要的角色。研究发现黄芪甲苷通过降低肿瘤细胞程序性死亡配体(PD-L1)和B7-H3的表达,调节免疫细胞功能,抑制免疫抑制因子,减少肿瘤源性细胞外囊泡的释放,并促进巨噬细胞从M2型向M1型的极化,有效重塑了TIME,从而显著增强了抗肿瘤免疫反应。本综述系统分析了黄芪甲苷在重塑TIME中的作用及其在抗肿瘤治疗中的潜在机制。未来的研究应进一步探索黄芪甲苷的分子机制,以期优化其在肿瘤治疗中的应用。
Abstract:Tumor immunosuppressive microenvironment (TIME) plays a crucial role in tumor growth and immune escape. A number of studies have found that Astragaloside Ⅳ (AS-Ⅳ) effectively reshaped TIME by reducing the expression of programmed cell death ligand 1 (PD-L1) and B7-H3 in tumor cells, regulating the function of immune cells, inhibiting immunosuppressive factors, reducing the release of tumor-derived extracellular vesicles, and promoting the polarization of macrophages from M2 type to M1 type. Thus, the anti-tumor immune response can be significantly enhanced. This review systematically analyzes the role of AS-Ⅳ in remodeling TIME and its potential mechanism in antitumor therapy. Future studies should further explore the molecular mechanism of AS-Ⅳ with a view to optimizing its use in tumor therapy.
