Background & Aim: Acute liver damage, inflammation and oxidative stress are underlying tissue necrosis and development of ciroces. The aim of this study was to evaluate the effect of Satureja bakhtiarica extract on acute liver disease induced by the thioacetamide and TNF-α and IL-6 cytokines level.  Experimental: In experimental study, 36 Wistar ...

To evaluate the importance of the proinflammatory cytokines TNF and lymphotoxin-alpha (LT alpha) in an experimental model of Staphylococcus aureus sepsis and arthritis, we used TNF/LT alpha-double-deficient mice raised on the C57BL/6 background. Mice were i.v. inoculated with a toxic shock syndrome toxin-1 (TSST-1)-producing S. aureus strain, LS-1. Intravenous inoculation of a high dose of bact...

According to the cancer immunoediting concept, inflammatory mediators play not only a critical role in promoting host protection against cancer but also contribute to cancer cell growth and survival. TNFis a critical factor in this network. However, the mechanisms underlying the tumor-promoting effect of TNFhave not been fully elucidated yet. We previously reported that in vitro culture of Lewi...

Objective(s): To observe and determine the effect and mechanism of psoralen on tumor necrosis factor-α (TNF-α)-induced muscle atrophy.Materials and Methods: Three sets of C2C12 cells, including blank control, TNF-α (10 or 20 ng/ml) treatment and a TNF-α (10 or 20 ng/ml) plus psoralen (80 μM) administration were investigated. Cell viabili...

Tumor necrosis factor alpha (TNF-alpha) activates both apoptosis and NF-kappaB-dependent survival pathways, the former of which requires inhibition of gene expression to be manifested. c-FLIP is a TNF-alpha-induced gene that inhibits caspase-8 activation during TNF-alpha signaling. Adenovirus infection and E1A expression sensitize cells to TNF-alpha by allowing apoptosis in the absence of inhib...

the aim of this study was to investigate the immunomodulatory effects of spirulina platensis (s.platensis) by measuring the levels of serum interleukin (il)-4, il-10, il-17, tumor necrosis factor(tnf)-α and interferon (ifn)-|γ| in mice suffered from systemic candidiasis and breast cancer. theaqueous extract of s. platensis was selected for this study. balb/c female mice were inoculated withcand...

The efficacy of radiation therapy for lung cancer is limited by radiation-induced lung toxicity (RILT). Although tumor necrosis factor-alpha (TNF-α) signaling plays a critical role in RILT, the molecular regulators of radiation-induced TNF-α production remain unknown. We investigated the role of a major TNF-α regulator, Tristetraprolin (TTP), in radiation-induced TNF-α production by macrophages...

Objective(s): It is generally believed that the inflammatory response in bone marrow mesenchymal stem cells (BMSCs) transplantation leads to poor survival and unsatisfactory effects, and is mainly mediated by cytokines, including interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α). In this study, we explored the mechanisms underlying the TNF-α-induced inflammatory ...
