The proinflammatory cytokines interleukin (IL)-1beta and IL-18 are supposed to play a crucial role in the pathogenesis of human inflammatory bowel disease. To exert biological activity, the precursors of both IL-1beta and IL-18 need to be cleaved by the interleukin-1beta-converting enzyme (ICE). IL-18 induces the synthesis of IFN-gamma in T cells and NK cells. In the present study, we investiga...

aim : to induce acute colitis progresses to chronicity in c57bl/6 mice by dextran sulfate sodium.   background : murine models are essential tools to understand ibd pathogenesis. among different types of chemically induced colitis models, the dextran sulfate sodium (dss)-induced colitis model is the most common model of ibd, due to its simplicity. patients and methods : male c57bl/6 mice 6–8 we...
