Background: Pre-eclampsia (PE) is one of the most important and life-threatening pregnancy disorders that affect at least 3-5% of all pregnancies. Imbalance in helper T cell functions may play a role in predisposing to PE or severity of the disease. Elevated frequencies of Th17 cells in the peripheral blood of PE patients have been reported. Several single nucleotide polymorphisms (SNP) within ...

background : interleukin (il)-4 is a member of t helper 2 (th2) axis produced by t-lymphocyte and mast cell. it has been shown that il-4 expression changes in tumor tissues. the main objective of this study is to investigate the expression of il-4 mrna in patients with laryngeal squamous cell carcinoma (lscc) with or without lymph node involvement. materials and methods: mrna expression of il-4...

RNA-RNA in situ hybridization was used to study the frequency of cells producing mRNA for IL-2 and IL-2-R in T lymphocytes stimulated by either of three mitogens: anti-CD3, anti-CD28, or PHA. Both CD4+ and CD8+ T cells expressed transcripts for IL-2 and the low-affinity IL-2-R when stimulated with these mitogens plus PMA. IL-2 transcripts peaked at 8-16 h, and IL-2-R at 24-40 h. Cyclosporin A (...

An interleukin 1 alpha (IL-1 alpha) cDNA probe and an IL-1 responsive T-cell clone (D10.G4; half-maximal stimulation, 0.1-1 pM) have been used to study the production of IL-1 by primary murine cell populations, particularly macrophages and dendritic cells. Spleen and peritoneal macrophages produced IL-1 mRNA and released biologically active IL-1 when challenged with lipopolysaccharide (LPS). In...

BACKGROUND Mice deficient in interleukin-2 (IL-2) develop inflammatory bowel disease resembling ulcerative colitis in humans. Recent studies provided evidence that alpha beta T cells, particularly CD4 T cells, rather than B cells, are involved in the pathogenesis of bowel inflammation of IL-2 deficient mice. AIM To analyse the pattern of expression of cytokine mRNA in intestinal tissue of nor...

Interleukin (IL)-25 is a recently described T helper 2 (Th2) cell-derived cytokine that belongs to IL-17 family and induces the production of IL-4, IL-5, and IL-13 from an unidentified non-T cell population. Here, we show that mast cells are also potent IL-25-producing cells. When bone marrow-derived mast cells (BMMCs) were stimulated by IgE cross-linking, IL-25 mRNA was induced within 30 min i...

epidemiological and clinical studies indicate a close relationship between obesity and asthma. here, we determined the impact of diet-induced obesity on the expression levels of il-1β, irak-1 and traf-6 mrna as well as il-1β protein level and pathological changes in male wistar rat’s lung after sensitization with ovalbumin (ova). twenty male wistar rats divided into four groups, control with no...

The chemokine thymus- and activation-regulated chemokine (TARC) induces selective migration of Th2, but not Th1, lymphocytes and is upregulated in the airways of asthmatic patients. The purpose of this study was to determine whether human airway smooth muscle (HASM) cells produce TARC. Neither IL-4, IL-13, IL-1beta, IFN-gamma, nor TNF-alpha alone stimulated TARC release into the supernatant of ...
