Inappropriate and chronic inflammatory responses underly the development of inflammatory bowel diseases (IBD), including both ulcerative colitis and Crohn’s disease. This process is an intertwined, inter-cellular cascade among diverse immune cells and tissue stroma. The interactions between immune and stromal cells not only propagate inflammatory responses but also regulate resolution of inflammation. Yet, we do […]

It is now well recognized that IBD develops as a result of complex gene-environment interactions. Since there is no cure for IBD, treatment has focused on alleviating the symptoms. A better understanding of the fundamental mechanisms that drive the development and progression of IBD would allow for the design of more specific and effective treatments. […]

The microbes that flourish within our guts are central to many aspects of human health. Which microbes are present can dictate susceptibility to a number of acute and chronic diseases, including IBD. This proposal will use a mouse model with a defined and stable set of bacteria to probe how mice interact with specific members […]

Pain is a major component of inflammatory bowel diseases, increasing the suffering of patients and decreasing their quality of life. However, the underlying cellular basis for pain in IBD and the role of pain-mediating neurons in driving gut dysfunction are not well known. Our goal is to characterize the role of neurons that mediate pain […]
