Abstract

Neutrophils enter sites of infection, where they can eliminate pathogenic bacteria in an oxidative manner. Despite their predominance in active tuberculosis lesions, the function of neutrophils in this important human infection is still highly controversial. We observed that virulent Mycobacterium tuberculosis survived inside human neutrophils despite prompt activation of these defence cells' microbicidal effectors. Survival of M. tuberculosis was accompanied by necrotic cell death of infected neutrophils. Necrotic cell death entirely depended on radical oxygen species production since chronic granulomatous disease neutrophils were protected from M. tuberculosis-triggered necrosis. More, importantly, the M. tuberculosis ΔRD1 mutant failed to induce neutrophil necrosis rendering this strain susceptible to radical oxygen species-mediated killing. We conclude that this virulence function is instrumental for M. tuberculosis to escape killing by neutrophils and contributes to pathogenesis in tuberculosis.

  • PMNs from chronic granulomatous disease patients lacking a functional NADPH-oxidase fail to succumb to necrotic cell death by wildtype M. tuberculosis but are also unable to kill attenuated strains.

    “Interestingly, PMNs from chronic granulomatous disease patients lacking a functional NADPH-oxidase fail to succumb to necrotic cell death by wildtype M. tuberculosis but are also unable to kill attenuated strains (120).”

  • Virulent M. tuberculosis strains use ROI-mediated necrosis as an escape mechanism from killing by PMNs.

    “These data suggest that virulent M. tuberculosis strains use ROI-mediated necrosis as an escape mechanism from killing by PMNs.”

  • Upon co-culture with M. tuberculosis, PMNs actively migrate toward the mycobacteria in vitro and become activated upon phagocytosis, as indicated by ROI production, IL-8 release, and generation of active cathelicidin, MPO, and NETs.

    “Upon co-culture with M. tuberculosis, PMNs actively migrate toward the mycobacteria in an in vitro assay and become activated upon phagocytosis as indicated by ROI production, IL-8 release and generation of active cathelicidin, MPO and NETs (120).”

    From Macrophage defense mechanisms against intracellular bacteria (2015) · cites this paper as [120]

  • Attenuated M. tuberculosis strains lacking the RD1 genomic virulence region extend the survival of PMNs before apoptotic suicide and are eventually killed in a ROI (MPO, NOX2)-dependent manner.

    “In contrast, attenuated M. tuberculosis strains lacking the RD1 genomic virulence region not only extend the survival of PMNs before apoptotic suicide but also eventually kills those attenuated strains in a ROI (MPO, NOX2)-dependent manner.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
