Expression and significance of Th1/Th2 cytokines in ankylosing spondylitis / 中国综合临床

ABSTRACT

Objective To investigate the changes and significance of Th1/Th2 cytokines in ankylosing spondyhtis (AS).Metbotis Serum and synovial fluid levels of TNF-α,IL.17.IL-10 and IL-4 were detected by en-zyme linked immunosorbent assay(ELISA)in AS cases.Results The serun levels of TNF-α,IL-17 and IL-10 were significantly higher,while the serum level of IL-4 Was significantly lower in AS group than in normal group.The levels of TNF-α.IL-17 and IL-4 in synovial fluid were significantly higher than in serum.Conclusion Disequilibrium exists in Th1/Th2 cytokine network of AS.and there is a strong predominance of Th1.
