Brucella abortus is a facultative intracellular bacterial pathogen that causes abortion in domestic animals and undulant fever in humans. IFN-γ, IL-12, and CD8+ T lymphocytes are important components of host immune responses against B. abortus. Herein, IFN-γ and IL-12/β2-microglobulin (β2-m) knockout mice were used to determine whether CD8+ T cells and IL-12-dependent IFN-γ deficiency would be ...

Neutrophils are an emerging cellular source of IFN-γ, a key cytokine that mediates host defense to intracellular pathogens. Production of IFN-γ by neutrophils, in contrast to lymphoid cells, is TLR- and IL-12-independent and the events associated with IFN-γ production by neutrophils are not understood. In this study, we show that mouse neutrophils express IFN-γ during their lineage development ...

conclusions moderate exercise for 8 weeks increased the ifn-γ and decreased the il-17 serum levels in the morphine-dependent rats. for this reason, this type of exercise can improve the function of the immune system during morphine withdrawal syndrome. results after 8 weeks of exercise, a significant increase was observed in the serum ifn-γ level in the ht group (251.17 ± 13.045) in comparison ...

Background: Management of multiple sclerosis (MS) is based on the usage of immunosuppressive and immune-modulating medications. Cytokines play an important role in the pathogenesis of MS. Objective: To evaluate the effects of rapamycin on the concentrations of Th1/Th2/Th17 serum cytokines in patients with MS. Methods: Six patients with relapsing remitting MS as a case group and 6 healthy indivi...

Background: In addition to humoral immunity associated with anti-desmoglein antibodies, cellular immunity and mediators including cytokines are involved in the pathogenesis of pemphigus vulgaris. In this study we evaluated the level of IL-2, IFN-γ, TNF-α, IL-4, and IL-10 in the sera of patients with pemphigus vulgaris before and after treatment.Methods: A total number of 71 new patients with pe...

The only available vaccine against pulmonary tuberculosis is Bacille Calmette-Guérin (BCG). As the efficacy reported of the vaccine is not up to the mark, there is an urgent need to develop improved anti-tuberculosis vaccines. Antigen 85B (Ag85B) is a very promising vaccine candidate molecule of Mycobacterium tuberculosis and interferon (IFN)-γ and has been considered the most attractive correl...

Indoleamine 2,3-dioxygenase (IDO) can locally suppress T cell-mediated immune responses. It has been shown that defective self-tolerance in early prediabetic female non-obese diabetic (NOD) mice can be attributed to the impaired interferon-gamma (IFN-γ)- induced IDO expression in dendritic cells of these animals. As IFN-γ can induce IDO in both dendritic cells and fibroblasts, we asked the ques...

Interferon gamma (IFN-γ) can induce a host antiviral response to foot and mouth disease virus (FMDV) in vivo and in vitro. To elucidate the mechanism of IFN-γ anti FMDV infection in host cells, high-throughput RNA sequencing was analyzed for systemic changes in gene expression profiles in PK15 cells infected by FMDV with or without IFN-γ pretreatment. More than 25 million reads, covering 1.2-1....
