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...

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...

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 ...

Tumor necrosis factor (TNF)-alpha has been implicated in several muscle-wasting disorders, with increased levels of the cytokine reported in malnourished children. The role of TNF-alpha in mediating malnutrition-induced inhibition of diaphragm (DIA) muscle growth in young growing rats was evaluated. Three groups of rats were studied: 1) control (CTL); 2) nutritional deprivation (ND; 50% of norm...

OBJECTIVE To clarify the efficacy and safety of anti-TNF-alpha therapy for intractable lupus nephritis. METHODS In nine patients with systemic erythematosus who presented with lupus nephritis resistant to steroids and immunosuppressants, 200 mg/body of infliximab was drip-infused three times. No changes were made to other treatments for three months after the start of anti-TNF-alpha therapy, ...

Necrotizing enterocolitis (NEC) is the most common gastrointestinal disease of premature infants. However, despite significant morbidity and mortality, the etiology and pathogenesis of NEC are poorly understood. Evidence suggests that ileal proinflammatory mediators such as IL-18 contribute to the pathology associated with this disease. In addition, we have previously shown that upregulation of...

BACKGROUND Tumor necrosis factor-alpha (TNF-alpha) has been reported to have an antiviral effect in vitro; however, its in vivo effect remains to be clarified. METHODS AND RESULTS To investigate the role of TNF-alpha in viral myocarditis using a murine model induced by encephalomyocarditis virus (EMCV), we evaluated (1) plasma TNF-alpha levels by enzyme-linked immunosorbent assay (ELISA), (2)...

INTRODUCTION Passive blockade of tumor necrosis factor-alpha (TNF-alpha) has demonstrated high therapeutic efficiency in chronic inflammatory diseases, such as rheumatoid arthritis, although some concerns remain such as occurrence of resistance and high cost. These limitations prompted investigations of an alternative strategy to target TNF-alpha. This study sought to demonstrate a long-lasting...
