Interleukin-1 receptor antagonist.
IL-1ra is the first described naturally occurring receptor antagonist of any cytokine or hormone-like molecule. IL-1ra is a member of the IL-1 family by three criteria: amino acid sequence homology of 26 to 30% to IL-1 beta and 19% to IL-1 alpha; similarities in gene structure; and common gene localization to human chromosome 2q14. Two structural variants of IL-1ra exist: sIL-1ra, a secretory m...
متن کاملInterleukin-6, interleukin-1 beta and interleukin-1 receptor antagonist levels in epileptic seizures
PURPOSE Data are accumulating to support the involvement of inflammatory mechanisms in the pathogenesis and course of epilepsy. METHODS The aim of this study was to examine seizure-induced changes in plasma concentrations of interleukin-6 (IL-6), interleukin-1 receptor antagonist (IL-1Ra), and interleukin-1 beta (IL-1β) in 23 patients with epilepsy undergoing a video-electroencephalography (E...
متن کاملProduction of interleukin-1 receptor antagonist and interleukin-1 beta by peripheral blood mononuclear cells is differentially regulated.
We studied the relationship between the production of the 23-Kd interleukin-1 receptor antagonist (IL-1ra) and IL-1 beta in cultures of human peripheral blood mononuclear cells (PBMC) using a specific radioimmunoassay for IL-1ra that had a sensitivity of 166 +/- 11 pg/mL. PBMC cultured without human serum made little IL-1ra or IL-1 beta. In the presence of 1% AB serum, there was no increase in ...
متن کاملLive Borrelia burgdorferi preferentially activate interleukin-1 beta gene expression and protein synthesis over the interleukin-1 receptor antagonist.
Lyme arthritis is one of the few forms of chronic arthritis in which the cause is known with certainty. Because cytokines are thought to contribute to the pathogenesis of chronic arthritis, we investigated the effect of the Lyme disease spirochete, Borrelia burgdorferi, on the gene expression and synthesis of IL-1 beta and the IL-1 receptor antagonist (IL-1ra) in human peripheral blood mononucl...
متن کاملHuman intestinal epithelial cells secrete interleukin-1 receptor antagonist and interleukin-8 but not interleukin-1 or interleukin-6.
BACKGROUND There is growing evidence that intestinal epithelial cells (IECs) are involved in the mucosal immune system. AIM To assess the pattern of cytokines secreted by IECs and lamina propria mononuclear cells (LPMNCs). To achieve this, the expression and secretion of interleukin (IL)-1, IL-1 receptor antagonist (IL-1ra), IL-6, and IL-8 in human primary colonic and ileal IECs and LPMNCs fr...
