    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.

    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.

    A frameshift in Yersinia pestis rcsD alters canonical Rcs signalling to preserve flea-mammal plague transmission cycles

    Xiao-Peng Guo, Hai-Qin Yan ... Yi-Cheng Sun
    Pseudogenization of rcsD alters canonical Rcs phosphorelay signalling and marks a significant adaptive evolutionary step in the emergence of ubiquitous extant branches of Yersinia pestis that can maintain stable plague outbreaks.

    The mutational signatures of poor treatment outcomes on the drug-susceptible Mycobacterium tuberculosis genome

    Yiwang Chen, Qi Jiang ... Qian Gao
    There are fourteen genomic variants of Mycobacterium tuberculosis that are significantly associated with poor treatment outcomes in drug-susceptible TB patients, but their predictive value is limited.

    A TRAF-like E3 ubiquitin ligase TrafE coordinates ESCRT and autophagy in endolysosomal damage response and cell-autonomous immunity to Mycobacterium marinum

    Lyudmil Raykov, Manon Mottet ... Thierry Soldati
    The Dictyostelium discoideum TRAF6 homolog TrafE coordinates the autophagy and ESCRT membrane repair machineries and works in the major cell-autonomous restriction pathway to control Mycobacterium marinum intracellular infection.

    Interactions between metabolism and growth can determine the co-existence of Staphylococcus aureus and Pseudomonas aeruginosa

    Camryn Pajon, Marla C Fortoul ... Robert P Smith
    The growth environment driven ratio of ATP to growth rate, called absolute growth, determines the final population composition of Staphylococcus aureus and Pseudomonas aeruginosa when in co-culture.

    A pH-dependent cluster of charges in a conserved cryptic pocket on flaviviral envelopes

    Lorena Zuzic, Jan K Marzinek ... Peter J Bond
    Benzene mapping simulations of envelope protein rafts from six different flaviviruses reveal a conserved cryptic site whose cluster of ionisable residues is likely responsible for orchestrating pH-dependent conformational changes during fusion, thereby representing an attractive target for antiviral development.

    Two enhancer binding proteins activate σ54-dependent transcription of a quorum regulatory RNA in a bacterial symbiont

    Ericka D Surrett, Kirsten R Guckes ... Tim I Miyashiro
    Genetic analysis and host colonization assays reveal a regulatory mechanism that enables a bacterial symbiont to bypass the constraints of quorum sensing to activate specific cellular traits necessary to colonize its host.

    Immunopeptidomics reveals determinants of Mycobacterium tuberculosis antigen presentation on MHC class I

    Owen Leddy, Forest M White, Bryan D Bryson
    Human macrophages infected with Mycobacterium tuberculosis present peptides derived from substrates of type VII secretion systems on MHC class I via a pathway dependent on the ESX-1 secretion system and independent of antigen processing by the proteasome and cathepsins.

    The antidepressant sertraline provides a novel host directed therapy module for augmenting TB therapy

    Deepthi Shankaran, Anjali Singh ... Vivek Rao
    Sertraline, a widely used antidepressant, enhances the potency of the standard antimycobacterial therapy in preclinical models of TB infection.
