ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of heat shock protein 72 (Hsp72) on the expression of IL-6 and IL-8 and activation of NF-kappaB in synoviocytes from patients suffered from rheumatoid arthritis (RA).</p><p><b>METHODS</b>IL6 and IL8 concentrations in culture supernatants were measured using enzyme-linked immunosorbent assays (ELISA). Nuclear translocation of NF-kappaB and degradation of the inhibitory protein IkappaBalpha were examined using immunohistochemistry and Western blot.</p><p><b>RESULTS</b>Hsp72 down-regulated IL-6 and IL-8 production in RA synoviocytes induced by tumor necrosis factor-alpha (TNF-alpha). Hsp72 inhibited nuclear translocation of NF-kappaB and degradation of IkappaBalpha induced by TNF-alpha.</p><p><b>CONCLUSION</b>Hsp72 has an anti-inflammatory effect on RA by down-regulation of IL-6 and IL-8 in synoviocytes, which is mediated through inhibiting the activation of NF-KalphaB signal pathways.</p>
