Humanized mouse model also may provide alternative solutions to current methods of adoptive transfer of xenogeneic human hemato-lymphoid cells e. Advances in this regard of using humanized mice to study IBD was demonstrated by Goettel et al. More recently, Goettel et al. In the new era of leveraging the power of data e.

These might render that traditional use of expensive animal models may be subsequently replaced by these alternatives in silico method to provide inference and insights on biological research with equivalent or even better outcomes. Similarly, these AI technologies can also be used in conjunction with animal models, e.

For example, Kozlowski et al. Indeed, AI technologies could be used to accelerate IBD research from fundamental studies including analysis of realworld data, to drug discovery and development, and in the clinic. The Nutritional Immunology and Molecular Medicine Laboratory, had created synthetic patient populations of CD and UC patients with properties of actual patient cohorts, and had built personalized predictive models of drug combinations and unravel complex relationships between diet, gut microbiome, immune system, and genetic lineup to determine the comparative treatment response in silico before testing in patients.

Overall, such approach may provide a more superior alternative method to traditional experimental colitis method of understanding the disease by allowing analysis of complex systems through crunching of big data. Increasingly sophisticated tissue organoids can model many aspects of diseases, including IBD, which may provide an alternative method to experimental animal models.

Use of organoid might also be beneficial in countries with strong regulations against animal testing. Several groups had demonstrated to ability to establish intestinal organoid system that can be used to understand disease pathogenesis.

Xu et al. In a separate study, Sarvestani et al. They concluded that these primary colonic organoid cultures from UC and nonIBD patients can be established that faithfully represent diseased or normal colonic states. A myriad of growth factors required in the culture medium also adds on to the cost involved.

Utilizing animal models have highly provided important insights into the pathogenesis of IBD although only limited percentage of clinical interventions from animal studies were subsequently developed into something that could be fit for patient use. However, major pathogenic factors as well as inflammatory modulators are unrevealed based on the genetically engineered mouse IBD models.

Alteration of multiple factors including innate immunity, adaptive immunity and epithelial defense play key roles during the development of IBD. In particular, animal models that incorporate variants of human IBD susceptibility genes have become indispensable roles to study these genes in chronic intestinal inflammation mechanistically and therapeutically.

Genetically Engineered Murine Models of IBD Recent advances on genetic engineering technologies allowed us to analyze the influences of overexpression or deficiency of particularly interesting genes during the development of IBD.

Open in a separate window. Chemically Induced IBD Models Currently, chemically induced colitis models belong to one of the most commonly used mouse IBD models since the onset of inflammation is immediate and the procedure is generally straightforward [ 18 ].

Small Molecules Small molecules medications remain the most common used first line of treatment for IBD. Signal Transduction Modulators Signal transduction modulators are one of the major groups of targets for the development of small molecule therapy for IBD. Cell Trafficking Modulators Cell trafficking modulators is the other major category that is being explored for the development of small molecule treatment for IBD.

Biologics Biological therapies have an increasing share in the modern therapeutics of various diseases including IBD. Table 1. Responses in Experimental Colitis Model to Biologics. Microbiota Gut microbiota dysbiosis represents another key factor involved in the pathogenesis of IBD and is now an attractive target for therapeutic development.
