The invention provides for methods of protecting neurons within the enteric nervous system (ENS) comprising administering an EGF receptor agonist, such as heparin-binding EGF (HB-EGF). These methods include reducing damage of ENS neurons in patient s suffering from an intestinal injury. In addition, the invention provides for increasing intestinal motility in a patient suffering from an intestinal injury comprising administering HB-EGF. The invention also provides for methods of inducing neurite growth within the ENS in a patient suffering from intestinal injury comprising administering HB-EGF.
