A microbiota-derived metabolite, a human colitis-on-chip, and a new angle on IBD barrier repair
In a new paper published by in Frontiers in Immunology the authors showed in a human colitis-on-chip that physiological lithocholic acid meaningfully reduced colitis-like damage by maintaining villus morphology, improving the barrier, and restoring epithelial proliferation, largely via FXR signaling.
It’s a strong example of how organ-on-chip models integrating epithelium, endothelium, and macrophages under flow, can capture multi-compartment effects that are invisible in simple monocultures and are difficult to dissect in animals.
Congratulations to Tim Kaden, Manuel Allwang, Johannes Stallhofer, Katja Graf, Martin Raasch and Alexander S. Mosig on this recent publication!
