Abstract:
Establishing a suitable animal model is important for studying the mechanism of inflammatory bowel disease (IBD) and exploring new therapeutic approaches. Although a large number of IBD single gene knockout animal models have been established, single knockout of certain genes associated with human IBD susceptibility does not manifest symptoms of IBD or manifest extremely milder symptoms, while composite animal models based on other modeling factors can better simulate the clinical features of IBD. This article mainly introduces three novel composite animal models and elaborates the possible pathogenesis of each composite model:animal models established by gene double knockout have more obvious and earlier symptoms than single-knockout models; single gene knockout model with Helicobacter infection can help to study the role of microbial infections in the pathogenesis of IBD; on the basis of gene knockout, specific deletion of certain immune cells can be used to study the role of the immune cells in the development of IBD. Among the above composite animal models, double knockout mice may be important animal models for IBD study.
