Background: There are strong evidences suggesting the secretion of different cytokines in cervical fluid during preterm labor. Betamethasone is widely administered for several reasons in preterm conditions. Objective: To Investigate the possible effect of betamethasone on endocervical cytokine concentration of women at risk of preterm labor. Methods: In a randomized clinical trial of 80 prime-g...

INTRODUCTION Interleukin (IL)-17 is a pro-inflammatory cytokine in rheumatoid arthritis (RA) and collagen-induced arthritis (CIA). Since interferon (IFN)-gamma inhibits Th17 cell development, IFN-gamma receptor knockout (IFN-gammaR KO) mice develop CIA more readily. We took advantage of this model to analyse the mechanisms of action of IL-17 in arthritis. The role of IFN-gamma on the effector m...

the aim of this study was assessing the adjuvant therapy of exercise on cytokines balance in mice with breast cancer tumor. twenty female balb/c mice were randomly assigned to experimental and control groups. after orientation in the environment, estrogen-receptor dependent breast cancer cells (mc4-l2) were injected to them and experimental group performed endurance training 5 day in week for 6...

Objective(s):With regard to pharmacological effects of carvacrol on the respiratory system, its effect on cytokines genes expression in splenocytes of asthmatic mice was examined in this study. Materials and Methods:Splenocytes were isolated from non-sensitized (control group), sensitized mice to ovalbumin (OVA) (group S), and S animals treated with dexamethasone, and three concentrations of c...

IFN-α exerts multiple effects leading to immune protection against pathogens and cancer as well to autoimmune reactions by acting on monocytes and dendritic cells. We analyzed the versatility of human monocytes conditioned by IFN-α towards dendritic cell differentiation (IFN-DC) in shaping the autologous T-helper response. Priming of naïve CD4 T cells with autologous IFN-DC in the presence of e...

IFN-beta currently serves as one of the major treatments for MS. Its anti-inflammatory mechanism has been reported as involving a shift in cytokine balance from Th1 to Th2 in the T-cell response against elements of the myelin sheath. In addition to the Th1 and Th2 groups, two other important pro-inflammatory cytokines, IL-17 and osteopontin (OPN), are believed to play important roles in CNS inf...

Interleukin (IL)-17 is exclusively produced by CD4 helper T-cells upon activation. It most often acts as a pro-inflammatory cytokine, which stimulates the release of pro-inflammatory cytokines IL-6, IL-8, TNF-α, and granulocyte-macrophage colony-stimulating factor (GM-CSF). In this study, we studied the in-vitro IL-17 response to specific antigens and a variety of mitogens and compared the IL-1...

Interleukin-17 (IL-17) is a signature cytokine of Th17 cells. Previous research has indicated that IL-17 plays a proinflammatory role by exacerbating interferon-γ (IFN-γ)-induced inflammation. However, prior to this study, it was not known whether inducible nitric oxide synthase (iNOS or NOS2), a signature molecule of inflammation, could be intensified by IL-17 when combined with IFN-γ. Thus, w...

We showed that Borrelia burgdorferi-vaccinated interferon gamma-deficient (IFN-gamma(0)) mice challenged with the Lyme spirochete developed a prominent chronic severe destructive osteoarthropathy. The immune response underlying the development of the severe destructive arthritis involves interleukin-17 (IL-17). Treatment of vaccinated IFN-gamma(0) mice challenged with B. burgdorferi with anti-I...

PURPOSE The purpose of this study was to evaluate Interferon (IFN)-γ and Interleukin(IL)-17 profiles in patients with different clinical presentations of pulmonary tuberculosis (TB) and to compare them with those of tuberculin-negative and tuberculin-reactive healthy controls METHODS Peripheral blood mononuclear cells (PBMCss), isolated from patients (n=52) and controls (n=30), were stimulate...
