objective(s):pentoxifylline is an immunomodulatory and anti-inflammatory agent and is used in vascular disorders. it has been shown that pentoxifylline inhibits proinflammatory [d1] cytokines production. the purpose of this study was to investigate the therapeutic effects of pentoxifylline on the treatment of autoimmune diabetes in mice. materials and methods: diabetes was induced by multiple l...

Although SHIP is a well-established suppressor of IgE plus Ag-induced degranulation and cytokine production in bone marrow-derived mast cells (BMMCs), little is known about its role in connective tissue (CTMCs) or mucosal (MMCs) mast cells. In this study, we compared SHIP's role in the development as well as the IgE plus Ag and TLR-induced activation of CTMCs, MMCs, and BMMCs and found that SHI...

OBJECTIVE Pregnant individuals of many species, including humans, are more sensitive to various bacteria or their products as compared with non-pregnant individuals. Pregnant individuals also respond differently to different bacteria or their products. Therefore, in the present study, we evaluated whether the increased sensitivity of pregnant women to bacterial products and their heterogeneous ...

background: repeated implantation failure (rif) is one of the most intricate obstacles in assisted reproduction. the cytokine and chemokine composition of uterine cavity seem to play important roles in the implantation process. objective: to compare the cytokine profile in the endometrium of normal fertile women and those with repeated implantation failure. methods: after enzymatic digestion of...

Dissecting the mechanisms of T cell-mediated immunity requires the identification of functional characteristics and surface markers that distinguish between activated and memory T lymphocytes. In this study, we compared the rates of cytokine production by virus-specific primary and memory CD8+ T cells directly ex vivo. Ag-specific IFN-gamma and TNF-alpha production by both primary and long-term...

In addition to its well-established effect on T cells, cyclosporin A (CsA) also inhibits inflammatory cytokine production by macrophages. However, little is known about the mechanism of action of CsA on macrophage cytokine production. We measured the effect of CsA on basal and phorbol-myristate-acetate (PMA)-stimulated production of interleukin-6 using the human monocyte cell line U937 differen...

this in vitro study was conducted to evaluate lymphocyte blastogenic and cytokine production by bovine peripheral blood mononuclear cells (pbmcs) stimulated with phytohemagglutinin (pha), pokeweed mitogen (pwm) and concanavalin a (con a) mitogens, by using tetrazolium salt and elisa tests, respectively. the results presented that  interleukin-2 (il-2), il-4, il-5, il-10, il-17 and ifn-γ product...

A shift toward Th2 cytokine production has been demonstrated during pregnancy and high dose estrogen therapy and is thought to be the primary mechanism by which estrogen suppresses the development of experimental autoimmune encephalomyelitis. However, low dose estrogen treatment is equally protective in the absence of a significant shift in cytokine production. In this study cytokine-deficient ...

Background: β-thalassemia as a hereditary disease is defined as defective synthesis of   β-globin chains, resulting in erythropoiesis abnormalities and severe anemia. Different studies have shown that cytokines and cytokine gene polymorphisms play a major role in the pathogenesis of   β-thalassemia. Single nucleotide polymorphisms (SNPs) within the promoter region or other regulatory sequences ...
