在这里, 我们描述了体外 培养条件、分离和细 粒棘球蚴细胞外囊泡 (EV) 的增加产生。通过动态光散射和透射电子显微镜对小型 EV 进行表征。使用共聚焦显微镜和流式细胞术研究骨髓来源的树突状细胞的摄取及其表型调节。

我们的研究重点是细粒棘球绦虫细胞外囊泡的表征及其在寄生虫-宿主相互作用中的作用。我们研究了宿主树突状细胞对成分的摄取以及对免疫调节的潜在影响。我们证明 E. granulosus EV 被树突状细胞吸收,影响成熟和抗原呈递。我们还确定了EV货物中的关键免疫调节和抗原蛋白,这些蛋白可能影响寄生虫与宿主的相互作用和免疫反应。

我们的方案优化了体外寄生虫培养,以增强小EV的产生,并确保高质量的分离,并整合树突状细胞测定来研究免疫调节。它可以整体应用,也可以部分应用。我们未来的研究将探索颗粒肠杆菌 EV 对免疫反应的体内影响、它们作为疫苗成分的潜力,以及它们对树突状细胞、微噬细胞和这些细胞免疫模型的影响。
