Response: The gut is densely innervated by pain fibers and we know that pain is associated with gut-related diseases. However, it is not so clear how pain fibers talk to the gut lining and barrier. We were interested to see that pain fibers were very close by the epithelial cells that line the gut, and in particular the goblet cells that produce mucus. We were wondering if mucus could be regulated by pain. Mucus is a key protective barrier that keeps our gut healthy by keeping harmful substances as well as bacteria away from the gut wall.
