These include IL10-/- colitis [one published study,73 and one referenced within the text of another110] and TNFΔARE ileitis.56 Several studies have used oil of mustard, croton oil, and LPS to induce colitis [detailed within a recent systematic review115] but these models are not classically felt to be experimental models of human IBD, although they may provide insight into intestinal inflammation in general. Here, IL10 is linked to Crohn ileitis.
