background: the pro-inflammatory cytokine, tumor necrosis factor-alpha (tnf-α), is a pathogenic element for a number of disorders. previous studies have reported that the -1031 t/c and -238 g/a polymorphisms in the promoter region of the tnf-α gene are important factors in reproductive-related disorders. one of the most common gynecological diseases of women during the reproductive years is end...

In the present studies we investigated the effect of interferon-alpha (IFN alpha) on the release of the soluble (extracellular) form of the tumor necrosis factor p55 receptor (TNFsRp55), because TNFsRp55 is a natural antagonist of tumor necrosis factor (TNF)-induced inflammation and also might be part of the antiinflammatory properties of IFN alpha. Plasma levels of TNFsRp55 were measured by a ...

Inflammation is portion of the body's immune response and it is basically a host protective response to tissue ischemia, injury, autoimmune responses or infectious agents. Although the information presented so far points to a detrimental role for inflammation in central nervous system (CNS) disease, it may also be useful. CNS demonstrates characteristic of inflammation, and in response to damag...

Many species of tea (Camellia sinensis) and cowslip (Echium amoenum) are used in Iranian traditional medicine. The aim of this study was to conduct the survey on the ability of Iranian black tea and cowslip extracts on secretion of tumor necrosis factor-alpha (TNF-alpha) by non-infected and infected mouse macrophages. A macrophage infection model with Legionella pneumophila and enzyme linked im...

A combination of adenosine (Ado) and homocysteine (Homo) enhances tumor necrosis factor (TNF)-alpha cytotoxicity in vitro and in vivo in several tumor cells. Ado and Homo at concentrations that enhanced TNF-alpha-mediated cytotoxicity accumulated S-adenosylhomocysteine (AdoHcy) and as consequence decreased the cellular methylation state, i.e. the ratio of S-adenosylmethionine to AdoHcy. This de...

Tumor necrosis factor-alpha (TNF-α) inhibitors are immunosuppressive agents used in a variety of inflammatory diseases, including rheumatoid arthritis (RA), spondyloarthritis, psoriasis, and bowel disease (IBD). Kaposi’s sarcoma (KS) is an angioproliferative associated with the human herpes virus 8 (HHV-8). We present 46-year-old male patient ankylosing spondylitis (AS) treated TNF-α inhibitor ...

Tumor necrosis factor (TNF)-alpha has been reported to modulate brain injury, but remarkably, little is known about its effects on neurogenesis. We report that TNF-alpha strongly influences survival, proliferation, and neuronal differentiation in cultured subventricular zone (SVZ) neural stem/progenitor cells derived from the neonatal P1-3 C57BL/6 mice. By using single-cell calcium imaging, we ...

Epithelial ovarian cancer cells express the chemokine receptor, CXCR4, which may be associated with increased survival and metastatic potential, but the regulation of this receptor is not understood. The inflammatory cytokine tumor necrosis factor-alpha (TNF-alpha) is found in ovarian cancer biopsies and is associated with increased tumor grade. In this report, we show that CXCR4 expression on ...
