OBJECTIVE To determine the relationship between the expression of interleukin-1beta (IL-1beta) and IL-1 receptor antagonists (IL-1ra) in the subacromial bursa and shoulder pain in rotator cuff diseases. METHODS Synovial specimens were analysed using various methods including reverse transcriptase-polymerase chain reaction (RT-PCR), immunohistochemistry and in situ RT-PCR. Thirty-nine patients...
Human bone marrow-derived mesenchymal stem cells (MSCs) have been observed to inhibit arthritis in experimental animal models such as collagen-induced arthritis. However, the exact anti-inflammatory mechanisms remain poorly understood. Interleukin-1 receptor antagonist (IL-1Ra) is an anti-inflammatory cytokine produced by immune and stromal cells. We postulated that MSCs could produce IL-1Ra an...
The proinflammatory cytokines IL-1α and IL-1β promote tumor angiogenesis that might be counteracted by the IL-1 receptor antagonist (IL-1Ra), anakinra, a clinically approved agent. A diet with high amounts of phytoestrogens, such as flaxseed (Flax), genistein (GEN), and the mammalian lignan enterolactone (ENL), may affect breast cancer progression in a similar fashion as the antiestrogen tamoxi...
PURPOSE To investigate the protective effects of interleukin-1 receptor antagonist (IL-1ra) gene transfer in a rat model of corneal graft rejection. METHODS We constructed a recombinant plasmid (pcDNA3.1-hIL-1ra) with high IL-1ra expression in eukaryotic cells. Using a Wistar-SD rat model of corneal graft rejection, we examined the effects of IL-1ra in vivo after cationic polymer jetPEI-media...
OBJECTIVES β-cell dysfunction and apoptosis associated with islet inflammation play a key role in the pathogenesis of type 2 diabetes (T2D). Growing evidence suggests that islet amyloid, formed by aggregation of human islet amyloid polypeptide (hIAPP), contributes to islet inflammation and β-cell death in T2D. We recently showed the role of interleukin-1β (IL-1β)/Fas/caspase-8 apoptotic pathway...
Human monocytes cultured on adherent IgG produce a specific IL-1 inhibitor that functions as a receptor antagonist (IL-1ra). This molecular has been purified, sequenced, cloned as a cDNA, and expressed in Escherichia coli. Recombinant IL-1ra has 17,000 mol wt and binds to IL-1 receptors on T lymphocytes, synovial cells, and chondrocytes with an affinity nearly equal to that of IL-1. These studi...
Polymorphonuclear leukocytes (PMN) have been identified as cells capable of producing a number of pro- and antiinflammatory cytokines in response to specific agonists. Previously, we showed that tumor necrosis factor (TNF), interleukin-1 beta (IL-1 beta), and IL-8, are produced by PMN after stimulation with agonists, such as lipopolysaccharide (LPS). In this study, we demonstrate that LPS is al...
Circulating concentrations of tumor necrosis factor-alpha (TNF), interleukin (IL)-1 beta, IL-6, IL-1 receptor antagonist (IL-1ra), and soluble TNF receptors p55 (sTNFr-55) and p75 (sTNFr-75) and ex vivo production of TNF, IL-1, IL-6, and IL-1ra using a whole blood culture system were measured during the acute and convalescent stages of meningococcal infection. Circulating TNF and IL-1 were belo...
PURPOSE This article investigates the relationship between cancer cells and stromal cells in carcinoma cell living microenvironment and elucidates the mechanism that interleukin-1 receptor antagonist (IL-1RA) blocks metastatic potential in colon cancer. METHODS Western blot and RT-PCR assay were used to determine the expression of hepatocyte growth factor (HGF) and IL-1α in colon carcinoma ce...
