Proinflammatory cytokines in the pathogenesis of inflammatory bowel diseases.

ABSTRACT: The cytokine responses characterizing the inflammatory bowel diseases are the key pathophysiologic elements that govern the initiation, evolution, and, ultimately, the resolution of these forms of inflammation. Studies during the last 2 decades now provide a detailed (but not yet complete) picture of the nature of these responses. The first tier of cytokine responses are governed by the T-cell differentiation patterns dominating the disease. In Crohn's disease, the major cytokines arise from T-helper cell (Th) 1 and Th17 CD4(+) T-cell differentiation and consist of interferon-γ and interleukin (IL)-17/IL-22 generated by these types of differentiation. The relative importance of these cytokines to Crohn's inflammation is still unclear, although evidence is mounting that interferon-γ is prim
