BACKGROUND Inhibitors of tumor necrosis factor alpha (TNFalpha) have demonstrated significant efficacy in chronic inflammatory diseases, including Crohn's disease (CD). To further elucidate the mechanisms of action of these agents, we compared the anti-TNFalpha agents certolizumab pegol, infliximab, adalimumab, and etanercept in several in vitro systems. (More)
