Background: Aloes have been used as medicinal plants for centuries. The immunomodulatory effect of Aloe vera has previouslybeen shown. Meanwhile, TNF-α, as an inflammatory cytokine, plays an essential role in defense against invading pathogen. Objectives: In the present study, the effects of A. vera extract gel and its fractions were investigated on the TNF-α production bymacrophages against Ca...

Background: Periodontitis and rheumatoid arthritis (RA) share a number of clinical and pathologic features, one of which is the presence of the tumor necrosis factor alpha (TNF-α)-induced bone resorption that is involved in the pathogenesis of both. Objectives: To investigate the effect of TNF-α blockade on periodontal conditions in patients with active RA. Method: The periodontal statuses of 3...

Tumor necrosis factor alpha (TNF-α) expression amplifies to excess amounts in several disorders such as rheumatoid arthritis and psoriasis. Although, Anti-TNF biologics have revolutionized the treatment of these autoimmune diseases, formation of anti-drug antibodies (ADA) has dramatically affected their use. The next generation antibodies (e.g. Fab, scFv) have not only reduced resulted immunoge...

background tnf-α is one of the most potent cytokines in proinflammatory reactions. results one hundred and twenty children with acute pyelonephritis were evaluated. urinary tnf-α/cr was 0.0051 ± 0.00083 pg/g creatinine. the authors found out a significant difference in urinary tnf-α/cr between patients who have normal and abnormal levels of urine leukocytes, urine protein, urine culture, erythr...

Objective(s): It is generally believed that the inflammatory response in bone marrow mesenchymal stem cells (BMSCs) transplantation leads to poor survival and unsatisfactory effects, and is mainly mediated by cytokines, including interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α). In this study, we explored the mechanisms underlying the TNF-α-induced inflammatory ...
