BACKGROUND Interleukin-25 (IL-25) is a potent activator of type-2 immune responses, and is responsible for airway inflammation in asthma. Previous reports have shown that IL-25 expressed hyper-reactivity in an experimental mouse-model of asthma. In addition, the production of IL-13/IL-5 promoted by nuocytes induced airway inflammation. Thus, it has been questioned whether blocking IL-25 against...
Background: The purpose of this study was to investigate the effect of concurrent training on pre-inflammatory (IL-1β, TNF-α) and anti-inflammatory (IL-10) cytokines gene expression in women with type2 diabetes. Methods: 18-patients (age30-38, >130 glycemic index) were selected, randomly, and divided into control (n=6) the concurrent training(diabetes, n=6) and the concurrent training (healthy...
Macrophage-derived chemokine (MDC) is a CC chemokine that recognizes the CCR4 receptor and is selective for T helper 2 (Th2) versus T helper 1 (Th1) cells. The present study was designed to investigate the effect of the prototypic Th2/Th1 cytokines, interleukin-4 (IL-4) and interferon-gamma (IFN-gamma), on the production of MDC by human monocytes. IL-4 and IL-13 caused a time-dependent (plateau...
Bacterial lipopolysaccharide (LPS) and interleukin (IL)-13 increase mucus secretion and inflammatory cytokine production in normal human bronchial epithelial (NHBE) cells. We evaluated the effect of club cell 10-kDa protein (CC10), an anti-inflammatory protein produced by epithelial cells, on mucus secretion, cell morphology and inflammatory cytokine production. NHBE cells were cultured at an a...
زمینه و هدف: اینترلوکین های 17 و 23 در دفاع بر علیه برخی عفونت های مخاطی دستگاه گوارش نقش دارند و il-17 باعث جذب نوتروفیل ها به محل عفونت شده و در ایجاد التهاب نقش دارد. مطالعه حاضر میزان بیان mrna سیتوکاین های il-17و il-23در دو گروه بیماران گاستریتی با عفونت هلیکوباکترپیلوری و فاقد عفونت را به وسیله روش کمی real-time pcr بررسی می کند. روش بررسی: در این مطالعه مورد- شاهدی، از 58 بیمار دارای گاس...
When mast cells are activated through their immunoglobulin (Ig)E receptors, release of low molecular weight mediators like histamine is followed by secretion of multiple cytokines, including interleukin (IL)-3, IL-4, IL-5, and granulocyte/macrophage colony-stimulating factor. Here we report that stimulated mast cells also synthesize IL-13 mRNA and protein; secretion of this cytokine may be of p...
Previously, we analyzed the proximal IL-4 promoter in directing Th2-specific activity. An 800-base pair proximal promoter conferred some Th2-selective expression in transgenic mice. However, this region directed extremely low reporter mRNA levels relative to endogenous IL-4 mRNA, suggesting that full gene activity requires additional enhancer elements. Here, we analyzed large genomic IL-4 regio...
There is currently no clear in vitro model to study the Th2 status atopic dermatitis (AD). Staphylococcus aureus, skin-homing cutaneous lymphocyte-associated antigen (CLA)+ memory T cells and IL-13 are key players AD. Circulating CLA+ reflect abnormalities We have studied CLA+/- T-cell response staphylococcal enterotoxin B (SEB) when cocultured with autologous lesional epidermal from adult non-...
BACKGROUND IL-13 is a critical mediator of allergic asthma and associated airway hyperresponsiveness. IL-13 acts through a receptor complex comprised of IL-13Ralpha1 and IL-4Ralpha subunits with subsequent activation of signal transducer and activator of transcription 6 (STAT6). The IL-13Ralpha2 receptor may act as a decoy receptor. In human airway smooth muscle (HASM) cells, IL-13 enhances cel...
