Intestinal inflammation is among the most prevalent health indications in the Western world. It comprises a range of diseases, from the less defined irritable bowel syndrome to full impairment of intestinal function in inflammatory bowel disease (IBD).
The development of preventative and therapeutic agents proved to be challenging as many of the processes involved in intestinal inflammation are still poorly understood. Reliable, robust, and high-throughput in vitro models that capture key aspects of intestinal inflammation are therefore essential for the drug development process but are still lacking. Additionally, each stage of the drug development process comes with its own specific demands in terms of complexity and screenability of the model, which further emphasizes the need for modular platforms that allow tailored biological complexity.
Together with Philip Morris International (PMI) we developed a 3D in vitro intestinal model consisting of epithelial and immune-competent cells. We demonstrated that intestinal inflammation can be induced or prevented by specific compounds, as assessed by changes in barrier function and cytokine release.
Finally, we showed how the biological complexity of the model can be adjusted, allowing us to optimize the combination of biological components relevant to intestinal inflammation and the specific research question.
