Lipopolysaccharide activates caspase-1 (interleukin-1-converting enzyme) in cultured monocytic and endothelial cells.
Interleukin-1 beta (IL-1 beta) is a pleiotropic proinflammatory cytokine. Mechanisms leading to its secretion include not only release of newly synthesized protein, but also cleavage of a preformed immature precursor protein into an active secretory form by the intracellular protease caspase-1 (formerly termed IL-1-converting enzyme [ICE]). Caspase-1 belongs to a rapidly growing family of cyste...
متن کاملFunctional role of interleukin 1 beta (IL-1 beta) in IL-1 beta- converting enzyme-mediated apoptosis
Prointerleukin-1 beta (pro-IL-1 beta) is the only known physiologic substrate of the interleukin-1 beta (IL-1 beta)-converting enzyme (ICE), the founding member of the ICE/ced-3 cell death gene family. Since secreted mature IL-1 beta has been detected after apoptosis, we investigated whether this cytokine, when produced endogenously, plays a role in cell death. We found that hypoxia-induced apo...
متن کاملCharacterization of the chicken interleukin-1beta converting enzyme (caspase-1) cDNA and expression of caspase-1 mRNA in the hen.
We have cloned and sequenced a chicken homolog to the mammalian interleukin-1beta (IL-1beta)-converting enzyme (caspase-1) cDNA and have evaluated caspase-1 mRNA expression in various tissues from the domestic hen, including ovarian follicle granulosa and theca layers. The deduced amino acid (aa) sequence of chicken caspase-1 is 44.9% identical to human caspase-1, and contains an active site pe...
متن کاملProapoptotic effects of caspase-1/interleukin-converting enzyme dominate in myocardial ischemia.
Caspase-1/interleukin-converting enzyme (ICE) is a cysteine protease traditionally considered to have importance as an inflammatory mediator, but not as an apoptotic effector. Because of the dual functions of this caspase, the pathophysiological impact of its reported upregulation in hypertrophy and heart failure is not known. Here, the consequences of increased myocardial expression of procasp...
متن کاملCaspase-1 inflammasomes in infection and inflammation.
Nucleotide-binding and oligomerization domain-like receptors (NLRs) constitute a family of germline-encoded pattern-recognition receptors, which allow the host to respond rapidly to a wide variety of pathogenic microorganisms. Here, we discuss recent advances in the study of a subset of NLRs, which control the activation of caspase-1 through the assembly of large protein complexes, inflammasome...
