We currently lack cures for chronic intestinal diseases. Despite incredible advances in understanding and targeting inflammation that promotes diseases like Crohn’s and ulcerative colitis, many patients develop resistance to treatment, suggesting alternative disease drivers beyond immune cells and the inflammatory molecules they produce. While the gut has remarkable regenerative capacity due to specialized stem cells that can rapidly generate all mature epithelial cells, diseases may impact underlying structural cells called fibroblasts which typically guide epithelial cell regeneration.
Our research vision is to identify the root causes of inflammatory diseases in the human gut. Our work suggests that fibroblasts play a central role, and our experiments to date have developed a unique and simple way to test how fibroblasts work closely with inflammatory immune cells. The specific internal cellular wiring diagrams and external cellular communication systems responsible for the identity and variety of fibroblasts that exist in the gut remain elusive. Our project aims to realize an integrative research plan that bridges careful human observation, computation and mechanistic experimental models. Our group is fundamentally interested in determining whether and how fibroblasts store and propagate disease in intestinal tissues to develop cures for IBD.
