Introduction: IFN-γ is one of the most important cytokines in the development of chronic inflammatory diseases such as asthma and COPD. The IFN-γ promoter methylation at CpG islands could be altered by various chemical and toxic substances which may have a role in the incidence of chronic pulmonary diseases and its severity. Thereby, the present study was aimed to evaluate the effect of sulfur ...

    Background & Aim: The immune system is quite capable to combat tumors and many immunological parameters including cytokines such as IL-12 & IFN-γ play major roles in this regard. IL-12 is also the major cytokine responsible for the differentiation of TH1 cells, which are potent producers of IFN-γ, IFN-γ in turn has a powerful enhancing effect on the ability of phagocytes to produce IL-12 as...

Abstract Plasmacytoid dendritic cells (pDCs) chronically produce type I interferon (IFN-I) in autoimmune diseases, including systemic sclerosis (SSc) and lupus erythematosus (SLE). We report that the IRE1α-XBP1 branch of unfolded protein response (UPR) inhibits IFN-α production by TLR7- or TLR9-activated pDCs. In SSc patients, UPR gene expression was reduced pDCs, which inversely correlated wit...

Interferon gamma (IFN-γ) is one of the key cytokines in defining T helper 1 lymphocyte immuneresponses. In this study, the bovine IFN-γ gene was cloned from spleen tissue RNA using the reversetranscription-polymerase chain reaction (RT-PCR). IFN-γ cDNA was sub-cloned and expressed inmammalian expression plasmid (pcDNA3.1(+)) under the control of the human cytomegalovirus (CMV)promoter. The pred...

Abstract Background and objectives: Dendritic Cells are the most important of antigen presenting cells with an effective role in immune tolerance. This study, aims to clarify the role of IFN- β in induction on dendritic cells derived by monocyte in diabetes type1 to evaluate the T cells response to beta cell specific antigenic molecule. Material and Methods: In this research, peripheral bl...
