    Listeria monocytogenes cell-to-cell spread in epithelia is heterogeneous and dominated by rare pioneer bacteria

    Fabian E Ortega et al.
    The pathogenic bacterium Listeria monocytogenes spreads infection using a two-tiered strategy, where most bacteria spread locally but a few 'pioneers' move further, increasing the likelihood of a persistent infection.

    ISG15 counteracts Listeria monocytogenes infection

    Lilliana Radoshevich et al.
    The induction of ISG15 during bacterial infection can be independent of Type I Interferons and leads to an increase in the secretion of cytokines known to be critical for bacterial clearance.

    Phenotypic complementation of genetic immunodeficiency by chronic herpesvirus infection

    Donna A MacDuff et al.
    HOIL-1 deficiency in mice results in a severe immunodeficiency that is effectively complemented by chronic infection with a murine gamma-herpesvirus.

    Cas9+ conditionally-immortalized macrophages as a tool for bacterial pathogenesis and beyond

    Allison W Roberts et al.
    Combination of stem cell engineering and CRISPR technologies created a facile method to genetically manipulate macrophages, a multifunctional cell type that plays critical roles in immunity, cancer, and tissue homeostasis.

    Chemotactic network responses to live bacteria show independence of phagocytosis from chemoreceptor sensing

    Netra Pal Meena, Alan R Kimmel
    Eukaryotic chemotaxis to live bacteria was quantified at a high throughput level, for the first time, and mechanistically examined for the interrelationship between chemotaxis and phagocytosis.

    Mycobacterium tuberculosis induces decelerated bioenergetic metabolism in human macrophages

    Bridgette M Cumming et al.
    Quantifiable bioenergetic parameters, determined from extracellular flux analyses, are distinct between macrophages infected with Mycobacteriumtuberculosis or vaccine strain M. bovis BCG, enabling assessment of future vaccine and drug efficacy.

    A randomised double blind placebo controlled phase 2 trial of adjunctive aspirin for tuberculous meningitis in HIV-uninfected adults

    Nguyen TH Mai et al.
    Adjunctive aspirin may reduce new brain infarcts and deaths in the first 60 days of treatment for HIV-uninfected adults with tuberculous meningitis.

    IFN-mediated negative feedback supports bacteria class-specific macrophage inflammatory responses

    Rachel A Gottschalk et al.
    Inflammatory dynamics are tailored to bacterial class through macrophage integration of microbial stimuli and cytokine feedback.
