Considerable evidence suggests that host genetic factor play an important role in the pathogenesis and clinical outcome of chronic hepatitis B virus (HBV) infection in several ethic groups. Association study was performed included 150 chronic HBV patients, 100 resolved hepatitis B and 150 healthy individuals with similar ethic background. Interestingly, human leucocyte antigen (HLA)-DR13 show a...

BACKGROUND AND OBJECTIVE The aim of our study was to investigate the influence of G-308 promoter variant of the tumor necrosis factor (TNF) alpha gene on metabolic changes and weight loss secondary to a high monounsaturated fat vs a high polyunsaturated fat hypocaloric diet in obese subjects. PATIENTS AND METHOD A sample of 261 obese subjects were enrolled in a consecutive prospective way, fr...

Objective: This work aimed of to review the implications anti-TNF-α therapy in COVID-19 patients associated with genetic polymorphism (TNF-α polymorphisms region-308) this pertinent cytokine Methodology: Electronic searches were carried out on PUBMED Central, BVS/BIREME, Web Science and The Cochrane Library aid key-words. Results: Twenty-six articles collected. Anti-TNF-α was interpreted evalua...

Introduction: The systemic and local content of inflammatory cytokines and chemokines play substantial roles in pathophysiology of arthritis. This study was purposed to verify the roles of synovial TNF-α, IL-6 and fractalkine (Fkn) in edema changes during different stages of Complete Freund’s Adjuvant (CFA)-induced knee arthritis in rats. Methods: 168 male Wistar rats were divided i...

late-onset alzheimer's disease (load) is a neurodegenerative disorder and the most common form of dementia affecting people over 65 years old. alzheimer’s disease is a complex disease with multi-factorial etiology. inflammation has been approved to have an important role in the pathogenesis of alzheimer’s disease (ad). tnf-a is a main pro-inflammatory cytokine that plays an essential role in in...

While previous studies have researched in association analyses between TNFα promoter polymorphisms and responses to TNF blockers in spondyloarthritis patients, their results were conflicting. Therefore, we aimed to determine whether TNFα promoter polymorphisms could predict response to TNF blockers and find the source of heterogeneity. Data were extracted and analyzed from published articles an...

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...

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 ...

Within a neonatal vitamin A supplementation (VAS) trial, we investigated the effect of VAS on TNF-α, IL-10, IL-5 and IL-13 production after lipopolysaccharide, purified protein derivative (PPD) of Mycobacterium tuberculosis and phytohaemagglutinin stimulation using a whole blood culture protocol. We found that VAS recipients had lower unstimulated TNF-α concentrations than placebo recipients. I...
