Objective(s):  Chlorpyrifos (CP) is a broad-spectrum organophosphorus pesticide used extensively in agricultural and domestic pest control, accounting for 50% of the global insecticidal use. In the present study, protective effects of two selenium-enriched strong antioxidative medicines IMOD and Angipars were examined in human lymphocytes treated with CP in vitro. Materials and Methods: Isolate...

Tumor necrosis factor receptor-associated factor 2 (TRAF2) is a critical mediator of tumor necrosis factor-α (TNF-α) signaling. However, the regulatory mechanisms of TRAF2 are not fully understood. Here we show evidence that TRAF2 requires brefeldin A-inhibited guanine nucleotide-exchange factor 1 (BIG1) to be recruited into TNF receptor 1 (TNFR1) signaling complexes. In BIG1 knockdown cells, T...

The effect of hypoxia on the release of tumor necrosis factor-α (TNF-α) in transformed rat retinal ganglion cells (RGCs) and the effect of agmatine on the hypoxia-induced production of TNF-α in RGCs were evaluated. RGCs were cultured under hypoxic conditions with 5% oxygen, with or without 100 μM agmatine. The expression levels of TNF-α and its receptor-1 (TNF-R1) were investigated by Western b...

OBJECTIVE This study investigated the effects of immune complexes (ICs) on tumor necrosis factor α (TNF-α) and B cell-activating factor (BAFF) production from U937 cells and further explored the mechanism. MATERIALS AND METHODS U937 cells were incubated with necrosis supernatant or systemic lupus erythematosus (SLE) sera alone, or their combination. The expression of TNF-α and BAFF was determ...

Anti-tumor necrosis factor-α (TNF-α) biological agents, including soluble TNF-α receptors and anti-TNF-α monoclonal antibodies, bring new hope for treating rheumatic diseases such as rheumatoid arthritis, but also increase the risk of infection, especially tuberculosis (TB) infection. Recent findings have shown that the physiological TNF-mediated signaling was somehow impaired by TNF antagonist...

The manifestation of the disease varies depending on the type of Leishmania and the immunestatus of the patient. Tumor Necrosis Factor (TNF)-α antag...

Toxins convert the hepatocellular response to tumor necrosis factor-α (TNF-α) stimulation from proliferation to cell death, suggesting that hepatotoxins somehow sensitize hepatocytes to TNF-α toxicity. Because nuclear factor-κB (NF-κB) activation confers resistance to TNF-α cytotoxicity in nonhepatic cells, the possibility that toxin-induced sensitization to TNF-α killing results from inhibitio...

objective: stevioside is a natural non-caloric sweetener which has been reported to have anti-inflammatory activity.  the aim of  the present study was to examine in vitro and in vivo effects of  stevioside on rats  plasma levels of tumor necrosis factor- α (tnf-α),  interleukin-1β (il-1β), tnf-α and il-1β release from lipopolysaccharide(lps)-stimulated rat peripheral blood mononuclear cells (p...

Although tumor necrosis factor-α (TNF-α) inhibits collagen-α1(I) gene expression in cultured hepatic stellate cells, assessment of its effects on hepatic collagen expression is complicated by the confounding variables of tissue necrosis and inflammation. Therefore, we analyzed whether chronically elevated serum TNF-α affects constitutive hepatic collagen metabolism in vivo by inoculating nude m...

background: since tumor necrosis factor‑α (tnf‑α) could be one of the risk factors at the development of diabetes complications; as well as serum leptin deficiency is related to increased susceptibility to infections in diabetic patients, they are potential indices from the preventive medicine viewpoint. this study was conducted to represent the effect of supplemental vitamin d3 on serum leptin...
