Methylation of IFN-γ in sulfur mustard-exposed patients
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 ...
متن کاملIFN-γ modulates Ly-49 receptors on NK cells in IFN-γ-induced pregnancy failure
We have previously shown that interferon gamma (IFN-γ) induces aberrant CD49b(+) natural killer (NK) cell recruitment by regulating CX3CL1 and eventually provokes foetal loss. In this study, we show that IFN-γ also modulates Ly-49 receptors on NK cells during pregnancy failure. The percentages of Ly-49A(+) and Ly-49G2(+) NK cells in the uteri of the IFN-γ-treated group were significantly lower ...
متن کاملبررسی پلی مورفیسم ژن های ( IFN-γ R1(-611 ، IFN-γ(2109) و( IL-12B (-1188 با بیماری سل ریوی
چکیده زمینه و هدف:. بسیاری از عوامل می توانند در پیشرفت بیماری سل دخیل باشند، اما فاکتور های ژنتیکی میزبان مهمترین نقش را در پیشرفت این بیماری دارند. یکی از این فاکتورهای ژنتیکی، پلی مورفیسم ژن‌های کد کننده ی سایتوکاین ها می باشد. مطالعات اخیر نشان می دهد که سایتو کاین هایی مانند IL-12 و IFN-γ نقش محوری را در تنظیم نوع، و میزان پاسخ های ایمنی در عفونت های مایکوباکتریومی بازی می کنند و موتاس...
متن کاملReduced IFN-γ Production in Chronic Brucellosis Patients
Background: Brucella is a well-known intracellular bacterium entailing acute and chronic illnesses in humans and domestic animals. The infection chronicity may be affected by the cell-mediated immunity and cytokine patterns. Objective: To evaluate the patterns of T-helper cytokines in patients suffering from chronic and acute brucellosis. Methods: In this cross-sectional study, 22 individuals w...
متن کاملSH2 Modified STAT1 Induces HLA-I Expression and Improves IFN-γ Signaling in IFN-α Resistant HCV Replicon Cells
BACKGROUND We have developed multiple stable cell lines containing subgenomic HCV RNA that are resistant to treatment with interferon alpha (IFN-α. Characterization of these IFN-α resistant replicon cells showed defects in the phosphorylation and nuclear translocation of STAT1 and STAT2 proteins due to a defective Jak-STAT pathway. METHODOLOGY/PRINCIPAL FINDINGS In this study, we have develop...
