Background: Rheumatoid arthritis (RA) is a chronic multisystem autoimmune disease common in all races and ethnics. Cytokines and cytokines receptors play an important role in RA pathogenesis and clinical presentation. Objective: To investigate the serum levels of TNF-α, TNF-α RI, TNF-α RII and IL-12 in RA patients and healthy control group. Methods: In this study 43 patients fulfilling the revi...
Introduction: Mycobacterium ulcerans is the etiological agent of Buruli ulcer (BU) the third most common mycobacterial infection in humans after tuberculosis and leprosy. BU is now considered by the WHO to be an emerging infection of major concern. M. ulcerans produces mycolactone toxin, which is required for the organism’s virulence. Mycolactone destroys tissue and suppresses host immune respo...
Background and Aims: Plants as medicines have always played a vital role in human life. Tumor necrosis factor alpha (TNF)-α is one of the macrophage-derived inflammatory cytokine with pleotropic effects in the inflammation process. Some studies have been demonstrated that some of the Echinops species have anti-inflammatory activity. In fact, Echinops lasilepis is introduced as one of the ...
Objective(s): Resistance to medications is one of the main complications in chemotherapy of cancer. It has been shown that some multidrug resistant cancer cells indicate more sensitivity against cytotoxic effects of TNF-α compared to their parental cells. Our previous findings indicated vulnerability of the mitoxantrone-resistant breast cancer cells MCF-7/MX to cell de...
Background: Pre-eclampsia is the most common critical condition during pregnancy. Plasma concentrations of tumor necrosis factor-alpha (TNF-α) and interleukin-1-beta (IL-1β) increase in pregnant women with pre-eclampsia, compared to normal pregnant women. Objective: To investigate the polymorphisms of IL-1β (C+3954T), TNF-α (G- 308A), and (G-238A) in preeclemptic women northeastern Iran. Me...
زمینه و هدف: ورزش های مقاومتی، اثرات متفاوتی بر بیماران دیابتی نسبت به ورزش های هوازی دارند. هدف از مطالعه حاضر تاثیر تمرین مقاومتی منظم بر روی سطوح پلاسمایی سایتوکاین های tnf-?و il-18 در رتهای سالم و دیابتی بود. روش بررسی: برای اجرای این مطالعه 32 رت سه ماهه از نژاد ویستار(محدوده وزنی 30±250گرم)انتخاب و به طور تصادفی به چهار گروه 8 تایی تقسیم شدند. جهت ایجاد دیابت در 17 موش از روش تزریق داخل ...
Introduction: Irritable bowel syndrome (IBS) is accompanied by abdominal pain and intestinal discomforts. A line of evidence shows that the immune system plays important roles in the pathogenesis of the disease. Two main cytokines directing the immune system are IL-6 and TNF-α which may play a role in the immunopathogenesis of this disease. The present study aimed at investigating the serum lev...
Background: Recent studies have shown that the course of cystic fibrosis in patients with this disease differs despite the same mutation in CFTR gene. We aimed to investigate the role of polymorphism in TNF α (-308) and TNF α (-863), and its effect on the phenotype of the patients with cystic fibrosis and progression of disease. Materials and Methods:...
objective: recent studies suggest that intermittent and prolonged normobaric hyperoxia (ho) results in ischemic tolerance to preventing ischemia brain injury. in this research attempts were made to see the changes in excitatory amio-acid transporter 3 (eaat3), tnf-α levels, and nf-κb activity following prolonged and intermittent nbho preconditioning. materials and methods: rats were divided i...
