During phagocytosis, microorganisms are taken up by immune cells into phagosomes. Through membrane-trafficking events mediated by SNARE proteins, phagosomes fuse with lysosomes, generating degradative phagolysosomes. Phagolysosomes contribute to host immunity by linking microbial killing within these organelles with antigen processing for presentation on(More)
Upon their internalization by macrophages, Leishmania promastigotes inhibit phagolysosome biogenesis. The main factor responsible for this inhibition is the promastigote surface glycolipid lipophosphoglycan (LPG). This glycolipid has a profound impact on the phagosome, causing periphagosomal accumulation of F-actin and disruption of phagosomal lipid(More)
UNLABELLED Myotonic dystrophy type 1 (DM1) is due to an unstable expansion of CTG repeat in the DMPK gene (19q13.3). The CTG repeat is highly polymorphic (5 to 37) in healthy individuals. According to the hypothesis that expanded (CTG)n alleles originated from larger normal alleles, there may exist a correlation between the prevalence of DM1 and the(More)
An intercellular spreading strategy using herpes simplex virus type 1 (HSV-1) VP22 protein is employed to enhance DNA vaccine potency of Leishmania major amastin antigen in BALB/c mice model. We evaluated the immunogenicity and protective efficacy of plasmid DNA vaccines encoding amastin-enhanced green fluorescent protein (EGFP) and VP22-amastin-EGFP.(More)
The protozoan Leishmania parasitizes macrophages and evades the microbicidal consequences of phagocytosis through the inhibition of phagolysosome biogenesis. In this study, we investigated the impact of this parasite on LC3-associated phagocytosis, a non-canonical autophagic process that enhances phagosome maturation and functions. We show that whereas(More)
Host lipid alterations are centrally involved in Leishmania donovani infection, and infected patients exhibit hypocholesterolemia. In this issue of Cell Host & Microbe, Ghosh et al. (2013) show that the metalloprotease GP63 released by L. donovani in the liver cleaves DICER1, inhibiting miR-122 maturation, which regulates cholesterol metabolism. These(More)
The potential emergence and spread of resistance to artemisinins in the Plasmodium falciparum malaria parasite constitutes a major global health threat. Hence, improving the efficacy of artemisinins and of artemisinin-based combination therapy (ACT) represents a major short-term goal in the global fight against malaria. Mice defective in the enzyme(More)
