Functional 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 کاملIL 1 B ( interleukin 1 , beta )
Other names: Catabolin; IL-1; IL-1B; IL1-BETA; IL1F2; pro-interleukin-1-beta HGNC (Hugo): IL1B Location: 2q13 Note: IL-1beta is a pro-inflamatory cytokine and is expressed by many cells including macrophage, NK cells, monocytes, and neutrophils. It belongs to the IL-1 family cluster that includes the IL-1a, and IL1-RN genes. The caspase 1 (CASP1/ICE) gene proteolitically activates IL-1β. This g...
متن کاملTransition from interleukin 1 beta (IL-1 beta) to IL-1 alpha production during maturation of inflammatory macrophages in vivo
In situ production of interleukin 1 alpha (IL-1 alpha) and IL-1 beta was investigated in Peyer's patches (PP) of mice undergoing an acute bacterial infection with Yersinia enterocolitica O8. Synthesis of IL-1 beta, as determined by immunohistochemistry, was found primarily in monocytes migrating into the inflamed PP. In comparison, synthesis of IL-1 alpha was temporarily delayed by at least 24 ...
متن کاملGranzyme A is an interleukin 1 beta-converting enzyme
Apoptosis is critically dependent on the presence of the ced-3 gene in Caenorhabditis elegans, which encodes a protein homologous to the mammalian interleukin (IL)-1 beta-converting enzyme (ICE). Overexpression of ICE or ced-3 promotes apoptosis. Cytotoxic T lymphocyte-mediated rapid apoptosis is induced by the proteases granzyme A and B. ICE and granzyme B share the rare substrate site of aspa...
متن کاملExpression of interleukin 1 beta and interleukin 1 beta converting enzyme by intestinal macrophages in health and inflammatory bowel disease.
BACKGROUND In the lipopolysaccharide (LPS) stimulated peripheral blood monocyte, the precursor form of interleukin 1 beta (IL-1 beta, 31 kD) is processed by IL-1 beta converting enzyme (ICE) to the mature, bioactive form (17 kD). IL-1 beta is a proinflammatory cytokine which is likely to have a role in the pathogenesis of inflammatory bowel disease (IBD). AIMS To investigate the expression an...
