Inhibitors of tumor necrosis factor-alpha (TNF-alpha) have been approved for treating rheumatoid arthritis. As one of the biological response modifiers, etanercept has also been used in the treatment of psoriatic arthritis and inflammatory bowel disease. While etanercept is effective, certain infectious complications, such as tuberculosis, fungus, and cytomegalovirus, have been reported. We rep...

We investigated the role of tumor necrosis factor alpha (TNF-alpha) in human peripheral monocytes infected with Legionella pneumophila in vitro. Exogenous TNF-alpha significantly inhibited the intracellular multiplication of the bacterium. This effect was concentration and time dependent and was abrogated by anti-TNF antibodies. TNF-alpha levels in the culture supernatants were low but were enh...

We report downregulatory effects of granulocyte colony-stimulating factor (G-CSF) on allogeneic immune responses in vitro. G-CSF did not affect the proliferative response of peripheral blood mononuclear cells (PBMC) against allogeneic Daudi cells but did inhibit tumor necrosis factor (TNF)-alpha secretion. In contrast with G-CSF, granulocyte-macrophage (GM)-CSF and interleukin (IL)-3 enhanced a...

Abstract. Our study aimed to establish a possible correlation between parathyroid hormone (PTH) levels and biomarkers of inflammation in hemodialysis patients with secondary hyperparathyroidism.
 Methods. This observational сross-sectional involved 108 hyperparathyroidism. The serum cytokines interleukin-1 (IL-1), IL-6 tumor necrosis factor-alpha (TNF-alpha) were determined all patients. c...

Recombinant human tumor necrosis factor-alpha (TNF-alpha) has demonstrable antitumor activity in transplantable murine tumor models and patients with cancer but is highly toxic to both animals and human beings. The narrow therapeutic index of TNF-alpha has limited its anticancer utility. Toxicity associated with many standard anticancer drugs is highly dependent upon the circadian timing of the...
