Pain and neuro-immune crosstalk in gut barrier function and colitis.

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 in IBD, and to determine whether inhibiting or activating these neurons leads to changes in the gut that can treat pain and inflammation.
