巨噬细胞通过其吞噬功能可清除炎症及肿瘤区域的病原体及坏死组织,在防御体系中发挥重要作用,当前肿瘤治疗常用的放疗化疗手段是引起细胞的凋亡,所形成的凋亡小体也依赖于巨噬细胞吞噬功能,但放疗化疗又同时造成巨噬细胞吞噬功能的降低,因此,研究吞噬细胞吞噬功能的提高有重要理论和实际意义. The phagocytosis function of macrophages can eliminate pathogens and necrotic tissues in the inflammation and tumor areas, and play an important role in the defense system. The current radiotherapy and chemotherapy used for tumor treatment is to cause cell apoptosis, and the formed apoptotic bodies are also Relying on macrophage phagocytosis, radiotherapy and chemotherapy also cause a decrease in phagocytosis of macrophages. Therefore, the study of the phagocytosis of phagocytic cells has important theoretical and practical significance.
