Peripheral, Placental and Cord Cytokines Profile in Spontaneous Labor and Elective Caesarean Section
Background: Cesarean section delivery can lead to much maternal morbidity. Different cytokines have been reported to be influenced by the mode of delivery. Objective: To investigate the influence of mode of delivery on maternal, placental and cord sera of interferon gamma (IFN-γ), interleukin-4 (IL-4) and interleukin-10 (IL-10) levels. Methods: These three cytokines were measured using ELISA in...
Background: Previous studies have shown that some cytokines have protective effects on cartilage in joint diseases. In the current study, effects of IL-4 against morphological changes and tissue degradation induced by IL-1α on bovine nasal cartilage (BNC) explants were investigated. Methods: Fresh BNC samples were prepared from a slaughterhouse under sterile conditions. BNC explants culture was...
the t helper 17 (th17) cells have been suggested to have osteoclast activating effects while t helper 2 (th2) cells are considered to have an osteoprotective role in periodontitis. this study was to compare the markers of th17 cells (rorc2 and il-17 genes) with that of th2 cells (il-4 and gata-3 genes) between healthy and periodontitis tissues.the samples were obtained from patients with period...
Interleukin 4 (IL-4) and IL-13 share many biological functions. Both cytokines promote growth of activated human B cells and induce naive human surface immunoglobulin D+ (sIgD+) B cells to produce IgG4 and IgE. Here we show that a mutant form of human IL-4, in which the tyrosine residue at position 124 is replaced by aspartic acid (hIL-4.Y124D), specifically blocks IL-4 and IL-13-induced prolif...

سابقه و هدف: ضایعات مزمن پریاپیکال دندان، عبارتند از بروز پاسخ التهابی مزمن در بافتهای اطراف انتهای ریشه دندان. نظر به اینکه سلولهای T helper، سلول غالب در این ضایعات میباشند، بنابراین این تحقیق با هدف تعیین رابطه میان غلظت IL-4 (به عنوان مهمترین سایتوکاین القا کننده تمایز T helper2) و IL-12 (به عنوان مهمترین سایتوکاین القا کننده تمایز سلولهای T helper 1) با اندازه ضایعات مزمن پریاپیکال...
