Caspase‐11 activates a canonical NLRP3 inflammasome by promoting K + efflux
Abstract
Recognition of microbe‐associated molecular patterns or endogenous danger signals by a subset of cytosolic PRRs results in the assembly of multiprotein signaling complexes, the so‐called inflammasomes. Canonical inflammasomes are assembled by NOD‐like receptor (NLR) or PYHIN family members and activate caspase‐1, which promotes the induction of pyroptosis and the release of mature interleukin‐1β/‐18. Recently, a noncanonical inflammasome pathway was discovered that results in caspase‐11 activation in response to bacterial lipopolysaccharide (LPS) in the cytosol. Interestingly, caspase‐11 induces pyroptosis by itself, but requires NLRP3, the inflammasome adapter ASC, and caspase‐1 to promote cytokine secretion. Here, we have studied the mechanism by which caspase‐11 controls IL‐1β secretion. Investigating NLRP3/ASC complex formation, we find that caspase‐11 functions upstream of a canonical NLRP3 inflammasome. The activation of NLRP3 by caspase‐11 during LPS transfection is a cell‐intrinsic process and is independent of the release of danger signals. Furthermore, we show that active caspase‐11 leads to a drop of intracellular potassium levels, which is necessary to activate NLRP3. Our study, therefore, sheds new light on the mechanism of noncanonical inflammasome signaling.

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.
