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...

conclusions the results indicated that there was a positive association between susceptibility to chronic hbv infection and tnf-α polymorphism. in addition, hbv patients carrying -308 gg, -857 cc, and -863 aa genotypes with lower serum levels of tnf-α had an increased risk of infection. background the host genetic background regulates the natural history of chronic hepatitis b virus (hbv) infec...

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...
