摘    要:为了探讨紫杉醇(Paclitaxel,PA)对小鼠不同组织巨噬细胞增殖和功能的影响。无菌操作制备小鼠腹腔、骨髓和脾脏巨噬细胞,在体外细胞培养体系中分别加入不同浓度40、80、160 ng/mL的PA和脂多糖(LPS)共培养,采用MTT法检测细胞增殖,ELISA和Griess法分别检测细胞分泌TNF-α和NO量,瑞氏-吉姆萨染色法测定腹腔巨噬细胞吞噬能力。结果表明: PA促进腹腔巨噬细胞和LPS诱导的腹腔和骨髓巨噬细胞增殖,但抑制脾脏和骨髓巨噬细胞以及LPS诱导的脾脏巨噬细胞增殖;PA抑制不同组织巨噬细胞分泌TNF-α,但促进腹腔和脾脏巨噬细胞分泌NO;PA提高了腹腔巨噬细胞吞噬鸡红细胞的能力。PA对小鼠不同组织巨噬细胞的免疫功能均有影响,这为进一步阐明PA的免疫调节机理提供了新的理论依据。

Abstract:To investigate the effects of Paclitaxel(PA) on proliferation and function of different tissue macrophages separated from mice. Peritoneal, bone marrow and spleen macrophages were prepared by aseptic technique and in vitro cultured in media containing different concentration of 40, 80,160 ng/mL PA alone or respectively together with lipopolysaccharide (LPS). Cell proliferation was detected by MTY, TNF-ot and NO level were assayed by ELISA and Griess methods respectively. Phagocytic ability of peritoneal macrophages was analyzed by Wright-Giemsa staining method. The results showed that PA could significantly promote peritoneal macrophage and LPS-stimulated peritoneal and bone marrow macrophages proliferation, but inhibit spleen and bone marrow macrophages and LPS-stimulated spleen macrophages. TNF-α secretion of different tissue macrophages was inhibited by PA, but NO secretion of peritoneal and spleen macrophages was promoted by PA. PA enhanced the phagocytosis of peritoneal macrophages to chicken red blood cells. PA had different impacts on the immune functions of different tissue macrophages from mice, which might be provided a new theoretical basis for the mechanism to regulate cellular immune function of PA.
Keywords:Paclitaxel  mice  macrophage  cellular immune function
