Project description:Leishmania RNA virus 1 (LRV1) is a double stranded RNA (dsRNA) virus found in some strains of the human protozoan parasite Leishmania, the causative agent of leishmaniasis, a neglected tropical disease. Interestingly, the presence of LRV1 inside Leishmania constitutes an important virulence factor which worsens leishmaniasis outcome in a type I interferon (type I IFN) dependent manner and contributes to treatment failure. Understanding how macrophages respond towards Leishmania alone or in combination with LRV1 as well as the role that type I IFNs may play during infection is fundamental to oversee new therapeutic strategies. In order to dissect the macrophage response towards infection, RNA Sequencing (RNA-Seq) was performed on murine wild-type (WT) bone marrow derived macrophages infected with Leishmania guyanensis (Lgy) devoid or not of LRV1 (LgyLRV1- and LgyLRV1+ respectively) or co-infected with LgyLRV1- and Lymphocytic choriomeningitis virus (LCMV) for 8 and 24 hours. Additionally, macrophages were treated with type I IFN (IFNα or IFNβ) after 6 hours of infection.

Project description:The genomic DNAs of strains JPCM5 and 263 of L. infantum, strains LV39 and Friedlin of L. major and strains Parrot-TarII and S125 of L. tarentolae were used in comparative genomic hybridizations to reveal the intra-species and inter-species gene content, and to validate L. tarentolae Parrot-TarII genome sequencing results. Leishmania (Sauroleishmania) tarentolae was first isolated in the lizard Tarentola mauritanica. This species is not known to be pathogenic to humans but is often used as a model organism for molecular analyses or protein overproduction. The Leishmania tarentolae Parrot-TarII strain genome sequence was resolved by high-throughput sequencing technologies. The L. tarentolae genome was first assembled de novo and then aligned against the reference L. major Friedlin genome to facilitate contig positioning and annotation, providing a 23-fold coverage of the genome. This is the first non-pathogenic to humans kinetoplastid protozoan genome to be described, and it provides an opportunity for comparison with the completed genomes of the pathogenic Leishmania species. A high synteny was observed in de novo assembled contigs between all sequenced Leishmania species. A number of limited chromosomal regions diverged between L. tarentolae and L. infantum, while remaining syntenic with L. major. Globally, over 90% of the L. tarentolae gene content was shared with the other Leishmania species. There were 250 L. major genes absent from L. tarentolae, and interestingly these missing genes were primarily expressed in the intracellular amastigote stage of the pathogenic parasites. This implies that L. tarentolae may have impaired ability to survive as an intracellular parasite. In contrast to other Leishmania genomes, two gene families were expanded in L. tarentolae, namely the leishmanolysin (GP63) and a gene related to the promastigote surface antigen (PSA31C). Overall, L. tarentolae appears to have a gene content more adapted to the insect stage rather than the mammalian one. This may partly explain its inability to replicate within mammalian macrophages and its suspected preferred life style as promastigote in the lizards.

Project description:Leishmania species are responsible for a broad spectrum of diseases, denominated Leishmaniasis, affecting over 12 million people worldwide. During the last decade, there have been impressive efforts for sequencing the genome of most of the pathogenic Leishmania spp. as well as hundreds of strains, but large-scale proteomic analyses did not follow these achievements and Leishmania proteome remained mostly uncharacterized. Here, we report a comprehensive comparative study of the proteomes of L. braziliensis, L. panamensis and L. guyanensis. Proteins extracted by SDS-mediated lysis were processed following the multi-enzyme digestion-filter aided sample preparation (FASP) procedure and analysed by high accuracy mass spectrometry. “Total Protein Approach” and “Proteomic Ruler” were applied for absolute quantification of proteins. Principal component analysis demonstrated very high reproducibility among biological replicates and a very clear differentiation of the three species. Our dataset comprises near 7000 proteins, representing the most complete Leishmania proteome yet known, and provides a quantitative picture of the proteomes of the three species in terms of protein concentration and copy numbers. We describe the abundance of proteins from the major energy metabolic processes, highlighting the main differences among the species. In addition, we provide quantitative data about different membrane proteins, transporters, and lipids, all of which delineate significant differences among those species and provide rich substrate for explore new molecules for diagnosing purposes.

Project description:Monocyte derived dendritic cells (MDDC) were infected with Leishmania major or Leishmania donovani parasites and collected at 4, 8, and 24 hours post-infection to analyze the differential effects those parasite species have on human host cell gene expression over time. Monocyte derived dendritic cells (MDDC) were generated from blood buffy coats collected from five anonymous healthy human donors and infected 10:1 (parasite to host cell) with Leishmania major Friedlin V1 strain or Leishmania donovani 1S strain parasites, where after 4, 8, or 24 hours total RNA was harvested from cells, cDNA generated, and hybridized to human gene transcipt expression arrays to assess differential host cell gene transcriptional expression differences relative to uninfected cells.
