Abstract

As the causative agent of hard-to-treat diffuse cutaneous leishmaniasis, Leishmania (L.) amazonensis persists in the host organism sheltered within large Parasitophorous Vacuoles (PVs) formed mainly in macrophages. In the present study, I present a simple and efficient method for L. amazonensis PV isolation. Isolated PVs are intact as demonstrated by the conservation of lysosomal probes loaded into PVs before the procedure. The method is useful for studies aiming at a complete and accurate molecular profile of these structures, to better understand the biogenesis of this pathogen-containing vacuole and its implication in parasite persistence and in leishmaniasis pathogenesis.

摘要

作为难治性皮肤利什曼病的病原体,亚马逊利什曼原虫(Leishmania)(L.)亚马逊ensis 存在于宿主组织中,被大型吞噬体空泡(PVs)所保护,这些空泡主要在巨噬细胞中形成。在本研究中,我提出了一种简单有效的亚马逊利什曼原虫 PV 分离方法。分离的 PV 是完整的,这可以通过在该过程之前加载到 PV 中的溶酶体探针的保留来证明。该方法可用于研究这些结构的完整和准确的分子谱,以更好地理解这种含有病原体的空泡的生物发生及其在寄生虫持续存在和利什曼病发病机制中的意义。
