Effect of Vitamin D treatment on Interleukin-2 and Interleukin-4 Genes expression in Multiple Sclerosis
Introduction: Multiple sclerosis is a chronic inflammatory disease of central nervous system. The etiology of MS is slightly known, but genetic and environmental factors are reported. Vitamin D regulates gene expression and affects target cell functions. The aim of this study was to investigate the expression variation of IL-2 and IL-4 genes under vitamin D supplementation in patients with mult...
متن کاملInterleukin-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 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...
متن کاملInhibition of Interleukin-1 Receptor-Associated Kinases 1/4, Increases Gene Expression and Serum Level of Adiponectin in Mouse Model of Insulin Resistance
Insulin resistance is a feature of most patients with type 2 diabetes mellitus. Epidemiological evidence suggests a correlation between inflammation and insulin resistant states such as obesity, but the underlying mechanisms are largely unknown. Interleukin-1 receptor-associated kinases (IRAK) play a central role in inflammatory responses by regulating the expression of various inflammatory gen...
متن کاملInterleukin-4 Suppresses Interleukin-1-Induced Expression of Matrix Metalloproteinase-3 in Human Gingival Fibroblasts
OBJECTIVE—In periodontitis, matrix metalloproteinase 3 (MMP-3, stromelysin 1) is present at increased levels in active disease sites compared to inactive or healthy sites, and the levels are correlated with clinical parameters and associated with progression of the disease. Interleukin 4 (IL-4) has been shown in other systems to suppress interleukin-1 (IL-1) induced expression of MMP-3, but thi...
