Core Tip
Core tip: Inflammatory bowel diseases (IBDs), including Crohn’s disease and ulcerative colitis are an immunolgically mediated disease with undetermined etiology. Evidence from animal and clinical studies demonstrate a positive correlation between an increased concentration of nitric oxide (NO) and the severity of the disease. Moreover, a positive correlation between NO production and increased pro-inflammatory cytokine levels [tumor necrosis factor-α, interleukin (IL)-6, IL-17, IL-12, and interferon-γ] were reported in patients with IBD. This review focuses on the role of cytokines in intestinal inflammation and their relationship with NO in IBD.
