The incidence of Inflammatory Bowel Disease is increasing worldwide in lockstep with modernization and worldwide ‘Westernization’ of lifestyles. One of the most important aspects of Westernization for human health is the adoption of a diet high in fat and sugar and low in fiber. Relatively little is known about how dietary sugar specifically affects the […]
The gut is composed of many cell types that contribute to its complex functions and ability to adapt to changing conditions associated with diet, lifestyles and the environment. Each of these factors can affect the health of the gut and contribute to intestinal disease such as inflammatory bowel disease and intestinal discomfort and pain. Many […]
To gain insight into IBD mechanisms and to improve the development of new therapeutics, an understanding of how genetic factors modulate intestinal homeostasis is required. We propose to model human IBD pathogenesis using gene editing in human embryonic stem cell-derived organoids to generate lines carrying mutations associated with IBD susceptibility. First, we will establish human […]
IBD patients have increased chances of developing colorectal cancer. Additionally this specific form of colon cancer is very difficult to treat. Despite numerous efforts we still do not fully understand the relationship between intestinal inflammation and the increased chance for colon cancer development. Understanding this will allow us to develop more specific and targeted prevention […]
Inflammatory Bowel Disease (IBD) can be a devastating illness. For reasons that are not clear, the cells that line the intestine in patients with IBD mount inappropriate immune responses toward the harmless bacteria that normally inhabit our gastrointestinal tracts. Treatments for IBD therefore involve suppressing immune responses to limit the damage caused by this immune […]
Inflammatory bowel disease is a debilitating chronic disease associated with inappropriate accumulation of white blood cells in the bowel. This causes tissue damage and is associated with pain, diarrhea, tiredness and weight loss. There are some effective drugs available that reduce the inflammation, but many patients will not respond to therapy. We have identified a […]
The gastrointestinal tract absorbs nutrients through the intestinal epithelium while controlling the resident bacterial community. A significant increase in the risk for inflammatory bowel diseases (IBDs) is associated with high cholesterol diets; dysbiosis, an imbalanced composition of gut bacteria, is an important hallmark of intestinal inflammation in patients with IBDs. However, the role of dietary […]
Inflammation is an integral part of immune defense against pathogens or tissue damage. However, inappropriate or prolonged inflammation has deleterious consequences and underlies many chronic diseases, especially inflammatory bowel diseases (IBD) like Crohn’s disease and colitis. Specialized immune sensors that reside inside the cell cytosol are of particular interest in IBD, because mutations in the […]
Gastrointestinal (GI) health is essential for overall body health. Inflammatory insults to the GI mucosa often cause profound and irreversible changes of GI homeostasis, including disrupted enteric neural regulation and subsequent alteration of GI function. Mucosal inflammation causes irreversible structural changes of the enteric nervous system (ENS), demonstrating a strong linkage between inflammation and GI […]
