Persistent inflammation observed in inflammatory bowel disease may be the consequence of an increased or aberrant immune response to normal gut constituents or an overall immune dysregulation and imbalance. Cytokines play an important role in immune regulation and interleukin 18 (IL-18) is one such cytokine that has emerged as being instrumental in driving CD4+ T cell responses towards a Th1-type. IL-18 can also directly mediate inflammation, moderate interleukin 1 activity, and can act on cell types other than T cells. It has been reported recently that IL-18 mRNA and protein are upregulated in gut tissue from IBD patients. The aim of this study was to understand more about the role of IL-18 in contributing to the pathology of IBD and to assess whether blocking IL-18 activity may be of therapeutic benefit as a treatment regimen for IBD.
