    High-speed, three-dimensional imaging reveals chemotactic behaviour specific to human-infective Leishmania parasites

    Rachel C Findlay, Mohamed Osman ... Laurence G Wilson
    High-speed holographic microscopy shows that Leishmania parasites modify their swimming behaviour to target human macrophages.

    Genome duplication in Leishmania major relies on persistent subtelomeric DNA replication

    Jeziel Dener Damasceno, Catarina A Marques ... Richard McCulloch
    Duplication of Leishmania chromosomes combines S-phase DNA replication initiated at a single internal region with subtelomeric DNA replication detectable outside S-phase, potentially explaining genome plasticity in this important parasite.

    Global genome diversity of the Leishmania donovani complex

    Susanne U Franssen, Caroline Durrant ... James A Cotton
    Genomic data for the parasites that cause visceral leishmaniasis provides the first global picture of the diversity and evolution of the pathogen and the epidemiology of this fatal tropical disease.

    Structure of the SAS-6 cartwheel hub from Leishmania major

    Mark van Breugel, Rainer Wilcken ... Christopher M Johnson
    The X-ray structure of the SAS-6 cartwheel hub from Leishmania major demonstrates that SAS-6 can be sufficient to determine centriolar cartwheel symmetry.

    Gene editing and scalable functional genomic screening in Leishmania species using the CRISPR/Cas9 cytosine base editor toolbox LeishBASEedit

    Markus Engstler, Tom Beneke
    LeishBASEedit enables gene editing in Leishmania without requiring DNA double-strand breaks, homologous recombination, or donor DNA, thereby facilitating loss-of-function screens via delivery of plasmid libraries and regardless of limitations due to gene copy number variations and/or lack of RNAi components.

    Stress conditions promote Leishmania hybridization in vitro marked by expression of the ancestral gamete fusogen HAP2 as revealed by single-cell RNA-seq

    Isabelle Louradour, Tiago Rodrigues Ferreira ... David Sacks
    Following exposure of Leishmania culture promastigotes to DNA stress, single-cell RNA sequencing reveals discrete clusters of cells associated with efficient generation of hybrids between different species and strains in vitro marked by expression of the ancestral gamete fusogen HAP2.

    Evolutionary genomics of epidemic visceral leishmaniasis in the Indian subcontinent

    Hideo Imamura, Tim Downing ... James A Cotton
    Genome sequencing reveals the evolution and epidemiology of Leishmania donovani in the Indian subcontinent, where epidemics have caused up to 30,000 deaths per year.

    The anti-tubercular drug delamanid as a potential oral treatment for visceral leishmaniasis

    Stephen Patterson, Susan Wyllie ... Alan H Fairlamb
    Biological and pharmacokinetic studies indicate that the anti-tubercular drug, delamanid, could be repurposed for the treatment of visceral leishmaniasis.

    Formation and three-dimensional architecture of Leishmania adhesion in the sand fly vector

    Ryuji Yanase, Flávia Moreira-Leite ... Jack D Sunter
    Using advanced volume electron microscopy, the ultrastructural and spatial organisation of Leishmania parasites strongly adhered to the gut of its sand fly vector was defined.

    Basalin is an evolutionarily unconstrained protein revealed via a conserved role in flagellum basal plate function

    Samuel Dean, Flavia Moreira-Leite, Keith Gull
    Basalins are intrinsically disordered proteins with astonishingly high-sequence divergence that are essential for building the transition zone basal plate and for proper central pair nucleation.
