Research Overview
Motilin
Motilin is a 22-amino-acid peptide released from the upper small intestine and is one of the classic physiologic prokinetic signals. It is a real peptide target for GI motility research, though not commonly used as a standard drug.
TFF3
TFF3 is a well-established mucosal repair factor in the literature, especially in the context of intestinal injury and inflammation. Experimental studies support a role in accelerating restitution and protecting the epithelial surface in gut disease models.
