Various dermatological conditions have been reported during tumor necrosis factor (TNF)-alpha-blocking therapy, but until now no prospective studies have been focused on this aspect. The present study was set up to investigate the number and nature of clinically important dermatological conditions during TNF-alpha-blocking therapy in patients with rheumatoid arthritis (RA). RA patients starting...

We have previously shown an unbalanced cytokine production in Fanconi anemia (FA) cells, ie, an underproduction of interleukin 6 (IL-6) during growth. Among a number of cytokines analyzed, the only other anomalies detected concern tumor necrosis factor alpha (TNF alpha). In comparison to normal cells, this cytokine is overproduced by FA lymphoblasts from the four genetic complementation groups....

We have analyzed the production of tumor necrosis factor alpha (TNF-alpha) induced by in vitro infection with African swine fever (ASF) virus (ASFV) and the systemic and local release of this inflammatory cytokine upon in vivo infection. An early increase in TNF-alpha mRNA expression was detected in ASFV-infected alveolar macrophages, and high levels of TNF-alpha protein were detected by ELISA ...

BACKGROUND Rat trachea display a differential topographical distribution of connective tissue mast cells (CTMC) and mucosal mast cells (MMC) that may imply regional differences in the release of allergic mediators such as tumor necrosis factor-alpha (TNF-alpha) and eicosanoids. AIM To evaluate the role of CTMC and MMC for release of TNF-alpha and eicosanoids after allergenic challenge in dist...

Tumor necrosis factor-alpha (TNF-alpha) is a polypeptide cytokine that has been associated with muscle wasting and weakness in inflammatory disease. Despite its potential importance in muscle pathology, the direct effects of TNF-alpha on skeletal muscle have remained undefined until recently. Studies of cultured muscle cells indicate that TNF-alpha disrupts the differentiation process and can p...

Tumor necrosis factor alpha (TNF alpha) stimulates production of granulocyte colony-stimulating factor (G-CSF) protein and mRNA in fibroblast cells. In contrast, TNF beta is at least 1,000-fold less potent than TNF alpha in increasing levels of G-CSF and GM-CSF activity and mRNA. The fibroblasts produce G-CSF and GM-CSF mRNA in a coordinate fashion after exposure to TNF. The ability of TNF alph...

Introduction: The role of adipose tissue as energy storage and endocrine organ is an area interest in the treatment several diseases. This study aimed to evaluate blood adiponectin (ADP), leptin, tumor necrosis factor type alpha (TNF-alpha) concentrations, their prognostic value patients with exacerbated chronic heart failure (CHF). Methods results: following were assessed 64 consecutive hospit...

The G-308A polymorphism of the tumour necrosis factor-alpha (TNF-alpha) gene, a variant that influences TNF-alpha transcription, may contribute to non-ischaemic dilated cardiomyopathy. To evaluate whether TNF-alpha genotyping may assist in identifying a subset of patients who could potentially benefit from immunomodulatory therapy, we assessed the relationship between the G-308A polymorphism of...

Tumor necrosis factor alpha (TNF-alpha) not only induces apoptotic signals but also causes antiapoptotic and regenerative responses in the liver. However, the molecular mechanism(s) of the latter events remains unclear. In the present study, we examined TNF-alpha-induced genes in Hc human normal (unsensitized) hepatocytes by cDNA microarray analysis. Interleukin-8 (IL-8) induction was the most ...

Apoptosis of neutrophils is a key mechanism to control the intensity of the acute inflammatory response. Previously, the cytokine tumor necrosis factor alpha (TNF-alpha) was reported by some to have pro-apoptotic and by others to have antiapoptotic effects on neutrophils. The aim of this study was to explain these contradictory results. We found that TNF-alpha at low concentrations strongly dec...
