Blockers of tumour necrosis factor-α: mechanisms of action

Tumour necrosis factor-α in nasal allergy

Tumour necrosis factor-alpha (TNF-alpha) was measured by enzyme-linked immunosorbent assay and eosinophil cationic protein (ECP) by radio-immunoassay to evaluate TNF-alpha in nasal allergy. There was no significant difference either between the mean concentrations of TNF-alpha in nasal secretions from the patients with perennial nasal allergy and those of normal subjects, or between the TNF-alp...

How tumour necrosis factor blockers interfere with tuberculosis immunity.

Tumour necrosis factor (TNF) is a potent inflammatory cytokine that plays an important role in immunity to numerous bacterial infections, including Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis (TB) in humans. Infliximab, adalimumab, certolizumab pegol and etanercept are anti-TNF agents used to treat a range of inflammatory/autoimmune diseases, such as rheumatoid arthrit...

Exogenous tumour necrosis factor α induces suppression of autoimmune arthritis

INTRODUCTION Our previous studies showed that arthritic Lewis (LEW) rats produced the highest levels of tumour necrosis factor (TNF)alpha in the recovery phase of adjuvant arthritis (AA), suggesting a correlation between high TNFalpha levels and reduced severity of arthritis. To further explore this correlation, we compared the TNFalpha secretion profile of the AA-resistant Wistar Kyoto (WKY) r...

Circulating tumour necrosis factor α and soluble tumour necrosis factor receptors in patients with different patterns of rheumatoid synovitis

Objective: To examine the relation between the serum levels of tumour necrosis factor α (TNFα), soluble tumour necrosis factor receptors (sTNF-R), and the histological pattern of rheumatoid synovitis. Methods: An enzyme linked immunosorbent assay (ELISA) was used to measure TNFα, p55 sTNF-R, and p75 sTNF-R concentrations in the serum of 43 patients with rheumatoid arthritis (RA) and 34 patients...
