Isolation of intact Leishmania amazonensis large parasitophorous vacuoles from infected macrophages by density gradient fractionation.

Isolation of intact Leishmania amazonensis large parasitophorous vacuoles from infected macrophages by density gradient fractionation. Exp Parasitol. 2020 Sep 14;:107989 Authors: Real F 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.
