pubmed:abstractText |
The anti-inflammatory effect of acetylsalicylic acid (ASA) has been thought to be secondary to the inhibition of prostaglandin synthesis. Because doses of ASA necessary to treat chronic inflammatory diseases are much higher than those needed to inhibit prostaglandin synthesis, a prostaglandin-independent pathway has been emerging as the new anti-inflammatory mechanism of ASA. Here, we examined the effect of ASA on the interleukin (IL)-1 beta- and tumor necrosis factor (TNF)-alpha-induced proinflammatory cytokine expression and evaluated whether this effect is closely linked to the nuclear factor (NF)-kappa B/I kappa B-alpha pathway. A high dose of ASA blocked IL-1 beta- and TNF-alpha-induced TNF-alpha and IL-8 expression, respectively. ASA inhibited TNF-alpha-induced activation of NF-kappa B by preventing phosphorylation and subsequent degradation of I kappa B-alpha in a prostanoid-independent manner. TNF-alpha-induced activation of I kappa B kinase was also suppressed by ASA pretreatment. These observations suggest that the anti-inflammatory effect of ASA in lung epithelial cells may be due to suppression of I kappa B kinase activity, which thereby inhibits subsequent phosphorylation and degradation of I kappa B-alpha, activation of NF-kappa B, and proinflammatory cytokine expression in lung epithelial cells.
