Abstract

Abstract Absent in melanoma 2 (AIM2) is a sensor of cytosolic DNA that is responsible for activation of the inflammasome and host immune responses to DNA viruses and intracellular bacteria. However, the role of AIM2 in host defenses against Mycobacterium tuberculosis is unknown. Here, we show that AIM2-deficient mice were highly susceptible to intratracheal infection with M. tuberculosis and that this was associated with defective IL-1± and IL-18 production together with impaired Th1 responses. Macrophages from AIM2-deficient mice infected with M. tuberculosis showed severely impaired secretion of IL-1± and IL-18 as well as activation of the inflammasome, determined by caspase-1 cleavage. Genomic DNA extracted from M. tuberculosis (Mtb DNA) induced caspase-1 activation and IL-1±/IL-18 secretion in an AIM2-dependent manner. Mtb DNA, which was present in the cytosol, co-localized with AIM2. Taken together, these findings demonstrate that AIM2 plays an important role in M. tuberculosis infection through the recognition of Mtb DNA.

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.
