Cytokines such as tumour necrosis factor-alpha are well-known mediators of the immune system, and treatment with a chimeric anti-tumour necrosis factor-alpha antibody (infliximab) has been shown to be highly effective in patients with Crohn's disease. Recent evidence indicates that infliximab induces apoptosis in lamina propria T lymphocytes in these patients. To better understand the mechanisms of infliximab's effect on gastrointestinal inflammation, we investigated changes in the serum level of cytokines after treatment in these patients, and the effect of infliximab in inducing the apoptosis of T lymphocytes.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>Thirteen patients with Crohn's disease were treated with infliximab at a dosage of 5-mg/kg body weight.
