Abstract

IKKbeta-dependent NF-kappaB activation plays a key role in innate immunity and inflammation, and inhibition of IKKbeta has been considered as a likely anti-inflammatory therapy. Surprisingly, however, mice with a targeted IKKbeta deletion in myeloid cells are more susceptible to endotoxin-induced shock than control mice. Increased endotoxin susceptibility is associated with elevated plasma IL-1beta as a result of increased pro-IL-1beta processing, which was also seen upon bacterial infection. In macrophages enhanced pro-IL-1beta processing depends on caspase-1, whose activation is inhibited by NF-kappaB-dependent gene products. In neutrophils, however, IL-1beta secretion is caspase-1 independent and depends on serine proteases, whose activity is also inhibited by NF-kappaB gene products. Prolonged pharmacologic inhibition of IKKbeta also augments IL-1beta secretion upon endotoxin challenge. These results unravel an unanticipated role for IKKbeta-dependent NF-kappaB signaling in the negative control of IL-1beta production and highlight potential complications of long-term IKKbeta inhibition.

  • Multiple components of molecular machinery for necroptosis-including ZBP1, RIPK3, MLKL, and TNFR1 (mainly via NF-κB)-impinge on control of inflammasome, a supramolecular platform for activation of CASP1 and consequent secretion of mature IL1B and IL18.

    “Importantly, multiple components of the molecular machinery for necroptosis—including ZBP1, RIPK3, MLKL, and TNFR1 (mainly via NF-κB)—impinge on the control of the so-called “inflammasome”, a supramolecular platform for the activation of CASP1 and consequent secretion of mature interleukin 1 beta (IL1B; best known as IL-1β) and IL18 [524–529].”

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.
