Abstract

Tuberculosis remains the most hazardous bacterial infection worldwide. The causative agent, Mycobacterium tuberculosis, is a facultative intracellular pathogen of resting MΦ. IFN‐γ secreted by natural killer, CD4 Th 1 and CD8 T cells upon instruction by IL‐12 and ‐18 activates MΦ to restrict mycobacterial growth. Production of both cytokines is induced by TLR signalling in DC and MΦ. Mice deficient for the TLR adaptor, MyD88, are highly susceptible to M. tuberculosis infection. Shared usage of MyD88 by signalling cascades for TLR and receptors for IL‐1 and IL‐18 prompted us to revisit the role of IL‐18 during experimental infection with M. tuberculosis. We show that mice deficient for IL‐18 and MyD88 but not for IL‐18 receptor promptly succumbed to M. tuberculosis infection in contrast to WT or TLR‐2/‐4 double KO mice indicating that lack of IL‐18 contributes to the high susceptibility of MyD88 KO mice to M. tuberculosis. Without IL‐18, the protective Th1 response was decreased and hence, mycobacterial propagation was favoured. Neutrophil‐driven lung immunopathology concomitant with unrestrained growth of tubercle bacilli are most likely responsible for the premature death of IL‐18 KO mice. Thus, IL‐18 plays a decisive role in protective immunity against tuberculosis.

  • Activated macrophages can limit growth of intracellular bacteria including M. tuberculosis and drive phagosome maturation toward phagolysosomes and auto-phagolysosomes.

    “Activated MΦs can limit growth of intracellular bacteria including M. tuberculosis and drive phagosome maturation toward phagolysosomes and auto-phagolysosomes (54, 55).”

  • IL-18 appears to be important to mount an efficient immune response because IL-18 knockout mice are more susceptible to M. tuberculosis infection than wildtype ones.

    “Similarly to IL-1β, IL-18 appears to be of importance to mount an efficient immune response because IL-18 knockout mice are more susceptible to M. tuberculosis infection than wildtype ones.”

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.
