IL-10 Knockout Model of Chronic Colitis

A Preclinical Model of Spontaneous Disease

The IL-10 knockout mouse develops chronic colitis over time and is used to test new prophylactic and therapeutic agents using a range of treatment schedules.

Why the IL-10 Knockout?

Spontaneous disease onset and the development of chronic colitis with a clinically relevant disease mechanism

IL-10 is a key anti-inflammatory cytokine secreted by immune cells, including regulatory Foxp3+ T cells and M2 macrophages. IL-10 and IL-10ra (the genes encoding IL-10 and the IL-10 receptor alpha subunit) are both candidate susceptibility genes for Inflammatory Bowel Disease in humans.

Deletion of the IL-10 gene results in dysregulated immune responses in the intestinal mucosa, allowing the establishment of inflammatory responses to antigens derived from the gut microbiome and the development of chronic colitis.  Similar to the adoptive T cell transfer model, the IL-10 knockout model is characterised by a Th1/Th17-type immune response, showing features such as epithelial hyperplasia, mixed inflammatory cell infiltration in the mucosa and submucosa, crypt abscess formation, occasional ulceration and the formation of cryptopatches.

New therapeutic strategies for treating inflammatory bowel diseases can be benchmarked against a validated reference item.
