An autologous colonic organoid-derived monolayer model to study immune: bacterial interactions in Crohn's disease patients.

Objectives: Crohn's disease (CD) initiation and pathogenesis are believed to involve an environmental trigger in a genetically susceptible person that results in an immune response against commensal gut bacteria, leading to a compromised intestinal epithelial barrier and a cycle of inflammation. However, it has been difficult to study the contribution of all factors together in a physiologically relevant model and in a heterogenous patient population.

Methods: We developed an autologous colonic monolayer model that incorporated the immune response from the same donor and a commensal bacteria, .
