The role of in utero endotoxin exposure in the development of inflammatory bowel disease in mice

Although early environmental influences are thought to influence the development of inflammatory bowel disease (IBD), little is known about the role of the in utero environment on subsequent IBD risk. We hypothesized that prenatal exposure to bacterial lipopolysaccharide (LPS) could modify the subsequent development of dextran sulfate sodium (DSS)‐induced ulcerative colitis in adulthood by influencing the associated cellular and immune response.
