Characterization 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 کاملLipopolysaccharide 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 کاملRab39a Binds Caspase-1 and Is Required for Caspase-1-dependent Interleukin-1β Secretion*
Interleukin-1beta (IL-1beta) is an important pro-inflammatory cytokine that is secreted by unconventional means in a caspase-1-dependent manner. Using a one-step immunoprecipitation approach to isolate endogenous caspase-1 from the monocytic THP1 cell line, we identified previously undescribed binding partners using mass spectrometry. One of the proteins identified was Rab39a, a member of the R...
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 کاملRegular Voluntary Exercise Potentiates Interleukin-1β and Interleukin-18 Secretion by Increasing Caspase-1 Expression in Murine Macrophages
Moderate-intensity regular exercise improves proinflammatory responses of lipopolysaccharide- (LPS-) stimulated macrophages. However, intracellular events that mediate the beneficial effects of exercise were unclear. This study aimed to clarify the mechanism by which regular voluntary exercise (VE) improves proinflammatory cytokine production by macrophages challenged with LPS. Peritoneal macro...
