Background & aim of research
Genetic studies have implicated the autophagy gene ATG16L1 and the endoplasmic stress (ER) gene XBP1 in the pathogenesis of Inflammatory Bowel Disease (IBD). Indeed, spontaneous inflammation develops in mice lacking ATG16L1 or XBP1 expression in intestinal epithelial cells (IEC). Because of the dominant role of failing autophagy and ER stress in IBD, we hypothesise that IEC stress contributes to intestinal fibrosis, gut dysmotility and pain during colitis.
This project aims, for the first time, to thoroughly comprehend the role of crucial IBD epithelial stress factors (i.e. ATG16L1 and XBP1 impairments) in enteric fibroblasts and neurons and to explore potential future intervention points.
