Interleukin (IL)-23 p19 expression induced by IL-1 in human fibroblast-like synoviocytes with rheumatoid arthritis via active nuclear factor- B and AP-1 dependent pathway

Abstract excerpt

OBJECTIVES: To explore the source of the p19 subunit of interleukin-23 (IL-23) in joints with rheumatoid arthritis (RA), the effects of IL-1beta and tumour necrosis factor (TNF)-alpha on IL-23 gene expression in RA fibroblast-like synoviocytes and the effect of IL-23 on proinflammatory cytokines. METHODS: Expression of IL-23 p19 in joints was examined by immunohistochemical analysis of patients with RA and...
