Interleukin-1 receptor antagonist knockout mice as a model of the inflammatory bowel disease

T
he inflammatory cytokine Interleukin 1 (IL-1) is an important mediator of inflammation and tissue damage in inflammatory
bowel disease (IBD). The activity of IL-1 is inhibited by a natural inhibitor: interleukin 1 receptor antagonist (IL-1Ra). The
balance between IL-1 and IL-1Ra plays a vital role in diseases. We investigated whether inflammatory bowel disease could be
induced spontaneously by the removal of IL-1Ra in mice. Histological staining was performed on BALB/Cmice to characterize
the morphology and enzyme activity of the small intestine from different ages and genotypes. Wild type mice served as a
negative control. 20 well oriented villi/crypt units and villus width at midvillus in longitudinal tissue sections were measured
in the jejunum and ileum. The number of goblet cells per villi was determined. Immuno histochemical staining was performed
to localise and detect MUC2, MUC5AC, MMP2, MMP9, ADAMTS1, IL-1β and TNFα. The results showed that there was a
significant decrease in the villi/crypts units’ height in the jejunum and ileum whereas the width of the villi was increased in the
jejunum and decreased in the ileum. The number of goblet cells per villi was increased in knockout mice compared with wild
type mice. Research is ongoing for the analysis of the immunohistochemistry. We conclude that IL-1Ra knockout mice could
act as a model for inflammatory bowel disease highlighting the importance of IL-1 in this disorder.
