To determine whether Crohn's disease and ulcerative colitis are characterized by discrete profiles of mucosal lymphokine production.
Isolated total cellular RNA from intestinal mucosal biopsies of healthy controls and patients with inflammatory bowel disease.
Quantified messenger RNA transcript levels for interleukin-2 (IL-2), IL-4, IL-5, and interferon-γ (IFN-γ) using quantitative reverse transcriptase polymerase chain reaction (RT-PCR).
Crohn's disease mucosal lesions exhibited significantly higher IL-2 and IFN-γ mRNA transcript levels compared with inflamed ulcerative colitis mucosa and healthy controls (p < 0.05), consistent with a Th1-like profile.
Ulcerative colitis involved tissue demonstrated significantly elevated IL-5 mRNA levels compared with healthy controls (p < 0.05) and active Crohn's disease lesions (p < 0.05), indicative of a Th2-like profile.

Implication

Comparative tissue analysis reveals distinct T-helper cytokine profiles in inflammatory bowel disease, indicating divergent immune mechanisms driving Crohn's disease and ulcerative colitis.
