我们已经开发了一个简单的和可重复的系统感染人巨噬细胞系(U937)与静止相杜氏利什曼原虫前鞭毛体。感染后4天,超过90%的前鞭毛体已转化为无鞭毛体。抗利什曼原虫药物别嘌呤醇核苷、福霉素B、9-去氮肌苷和葡萄糖酸锑钠对利什曼原虫的生长有明显的抑制作用。donovani无鞭毛体在这个细胞系。为了研究U937细胞系中无鞭毛体进行实验监测的生化反应的能力,我们将细胞与放射性标记的9-脱氮肌苷一起孵育。这种嘌呤类似物在无鞭毛体阶段进行代谢,类似于发生在前鞭毛体阶段。该细胞系可用于寄生虫成熟和分化、寄生虫-人相互作用和抗寄生虫药物的研究。
We have developed a simple and reproducible system for infecting a human macrophage cell line (U937) with stationary-phase Leishmania donovani promastigotes. Four days after infection, greater than 90% of the promastigotes had transformed to amastigotes. The antileishmanial agents allopurinol riboside, formycin B, 9-deazainosine, and sodium stibogluconate effectively inhibited the growth of L. donovani amastigotes in this cell line. To study the capability of amastigotes in the U937 cell line to carry out biochemical reactions that could be monitored experimentally, we incubated the cells with radiolabeled 9-deazainosine. This purine analogue underwent metabolism in the amastigote phase similar to that occurring in the promastigote phase. This cell line should be useful for studies of parasite maturation and differentiation, parasite-human interactions, and antiparasitic drugs.
