BACKGROUND Rats subjected to bile duct ligation (BDL) exhibit increased systemic oxidative stress and brain dysfunction characteristic of hepatic encephalopathy (HE), including fatigue, neurotransmitter alterations, cognitive and motor impairment, and brain inflammation. The levels of tumor necrosis factor-alpha (TNF-α) and asymmetric dimethylarginine (ADMA) are both increased in plasma and bra...

In the recent original research published on International Journal of Fertility and Sterility the association between tumor necrosis factor-alpha (TNF-α) genetic polymorphisms and endometriosis in 150 Iranian patients suffered this disease. The authors notably found a lower frequency of TNF-α -863C/A allele A among the affected patients in comparison with healthy women, although this difference...

recent studies have established that sex hormones directly or indirectly affect t and b cells and macrophages by manipulating the production of cytokines. in this study the possibility of the effect of 5a-dht on macrophage (mφ) nitric oxide (no) release via interleukin-l, 6 (ll-1β, il-6) or tumor necrosis factor-a (tnfα) was investigated. the endogenous cytokines il-1β, il-6 and tnf-α were neut...

Abstract Background: Breast cancer is the most common in women. The occurrence of metastasis breast should be detected early. Tumor necrosis factor-α (TNF-α) involved every step carcinogenesis process. A rise TNF-α level linked to advancement cancer. We aimed determine association between levels and metastases. Methods: An analytic cross-sectional study was conducted on women with treated at On...

Background: Tumor necrosis factor alpha (TNF-α) is a primary mediator of immune regulation and might be required in the early stages of DC development from CD34+ cells. However, details of optimal timing of exposure to TNF-α in DC development process in monocytes or non-purified hematopoitic cells are still lacking and clear benefits of this approach to the development of DCs remain to be valid...

background inflammatory bowel disease (ibd) is a chronic, relapsing, inflammatory disorder of the gastrointestinal tract that includes two entities, crohn`s disease (cd) and ulcerative colitis (uc). as with other complex diseases, both genetic susceptibility and environmental factors play role in the pathogenesis of these diseases. the tumor necrosis factor α (tnf-α) gene is located in the ibd3...

Although detrimental effects of tumor necrosis factor-α (TNF-α) have been reported in failing myocardium, clinical trials using TNF-α antagonists did not show the benefit of TNF-α inhibition in patients with chronic heart failure (CHF). The double-edged effects of TNF-α/Toll-like receptors (TLRs)-related proinflammatory cytokines and downstream signal transduction, nuclear factor (NF)-κB activa...
