The parasitophorous vacuoles (PVs) that insulate Leishmania spp.in host macrophages are vacuolar compartments wherein promastigote forms differentiate into amastigote that are the replicative form of the parasite and are also more resistant to host responses.We revisited the biogenesis of tight-fitting PVs that insulate L.

infantum in promastigote-infected macrophage-like RAW 264.7 Forecasting the biomass-based energy potential using artificial intelligence and geographic information systems: A case study cells by time-dependent confocal laser multidimensional imaging analysis.Pharmacological disassembly of the cellular microtubule network and silencing of the dynein gene led to an impaired interaction of L.

infantum-containing phagosomes with late endosomes and lysosomes, resulting in the tight-fitting parasite-containing phagosomes never transforming into mature PVs.Analysis of the shape of the L.infantum parasite within PVs, showed that factors that impair promastigote-amastigote differentiation can also result in PVs whose maturation is arrested.

These findings highlight the importance of the MT-dependent interaction of L.infantum-containing phagosomes with the host macrophage endolysosomal pathway LncRNA MCM3AP-AS1 sponges miR-148a to enhance cell invasion and migration in small cell lung cancer to secure the intracellular fate of the parasite.
