background: the role of mesenchymal stem cell in cellular therapy is the subject of interest for many researchers. the differentiation potential of mscs and abilities in modulations of the recipient’s immune system makes them important cells in tissue regenerative studies. mscs by releasing the proinflammatory cytokines play important role in immunomodulatory systems; however the signaling path...

The hyperlipidemia accompanying infection has been attributed to production of tumor necrosis factor. This cytokine inhibits adipose tissue lipoprotein lipase, which could decrease clearance of lipoproteins. Infections also increase hepatic lipogenesis. We now have demonstrated that tumor necrosis factor-alpha stimulates lipid synthesis in vivo. 2 h after administration of tumor necrosis factor...

Thus the pathophysiology of allergic asthma is traditionally explained by mast celland/or Th2 cell-mediated airway inflammation, which is a manifestation of the acquired immune response. On the other hand, recent studies have identified various other important molecules associated with phenotypes of asthma, including tumor necrosis factor (TNF)[2, 3] , thymic stromal lymphoprotein [4, 5] , inte...

Tumor necrosis factor alpha (TNF, TNFSF2) is an important multifunctional cytokine that regulates inflammation, host defense, immune responses, and apoptosis. TNF exists as a membrane-bound 26kDa, type II integral membrane protein, and a 17kDa soluble homotrimeric TNF that is generated via proteolytic cleavage by TNF-a converting enzyme (TACE, ADAM17). Both the membrane-bound and soluble forms ...

Tumor necrosis factor alpha (TNF-alpha) is a potent cytokine which regulates inflammation via the induction of adhesion molecules and chemokine expression. Its expression is known to be regulated in a complex manner with transcription, message turnover, message splicing, translation, and protein cleavage from the cell surface all being independently regulated. This study examined both cell line...

Hypertension can lead to subarachnoid hemorrhage and eventually to cerebral vasospasm. It has been suggested that the latter could be the result of oxidative stress and an inflammatory response evoked by subarachnoid hemorrhage. Because an unavoidable consequence of hemorrhage is lysis of red blood cells, we first tested the hypothesis on carotid arteries that the proinflammatory cytokine tumor...

background and aims: plants as medicines have always played a vital role in human life. tumor necrosis factor alpha (tnf)-α is one of the macrophage-derived inflammatory cytokine with pleotropic effects in the inflammation process. some studies have been demonstrated that some of the echinops species have anti-inflammatory activity. in fact, echinops lasilepis is introduced as one of the native...
