Background: Rheumatoid arthritis (RA) is a chronic multisystem autoimmune disease common in all races and ethnics. Cytokines and cytokines receptors play an important role in RA pathogenesis and clinical presentation. Objective: To investigate the serum levels of TNF-α, TNF-α RI, TNF-α RII and IL-12 in RA patients and healthy control group. Methods: In this study 43 patients fulfilling the revi...

Background: The expression of mouse tumor necrosis factor alpha (TNF-α) in Escherichia coli is a favorable way to get high yield of protein; however, the formation of cytoplasmic inclusion bodies, which is the consequence of insoluble accumulated proteins, is a major obstacle in this system. To overcome this obstacle, we used a pulsed dilution method to convert the product to its native c...

TNFα is one of the most important inflammatory cytokines which induces caspase and apoptotic process. There are two forms of TNFα: soluble TNFα (solTNFα) and transmembrane TNFα (tmTNFα). These inflammatory cytokines have two receptors namely TNRF1 and TNRF2. The attachments of the cytokines to those receptors induce the TRAF and activate the NK-Kb. TNFR1 is f...

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 ...

Background: Tumor necrosis factor- a (TNF-α) is a cytokine that was identified as a factor with a wide range of proinflammatory activities. The expression of bovine TNF-α in mammary tissue during pregnancy seems to have a role in development of the corresponding glands.Objective: Single nucleotide polymorphisms (SNPs) were defined in 3′-flanking region of...

Gemäß des Treat-to-Target-Konzepts empfiehlt das American College of Rheumatology für Patientinnen und Pa-tienten mit einer rheumatoiden Arthri-tis (RA), welche auf konventionelle syn-thetische DMARDs (disease-modifying antirheumatic drugs) nicht ausreichend ansprechen, die Umstellung bio-logische oder gezielte synthetische DMARDs. Die optimale Therapiereihen-folge ist allerdings unklar.
