Abstract

Dying cells are capable of activating the innate immune system and inducing a sterile inflammatory response. Here, we show that necrotic cells are sensed by the Nlrp3 inflammasome resulting in the subsequent release of the proinflammatory cytokine IL-1β. Necrotic cells produced by pressure disruption, hypoxic injury, or complement-mediated damage were capable of activating the Nlrp3 inflammasome. Nlrp3 inflammasome activation was triggered in part through ATP produced by mitochondria released from damaged cells. Neutrophilic influx into the peritoneum in response to necrotic cells in vivo was also markedly diminished in the absence of Nlrp3. Nlrp3-deficiency moreover protected animals against mortality, renal dysfunction, and neutrophil influx in an in vivo renal ischemic acute tubular necrosis model. These findings suggest that the inhibition of Nlrp3 inflammasome activity can diminish the acute inflammation and damage associated with tissue injury.

  • Necrotic cells can activate NLRP3, which is partly dependent on actively respiring mitochondria and the physiological release of ATP.

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.
