Research Overview
Glucagon-like peptide-2
Native GLP-2 is a key enteric growth factor with rapid degradation by DPP-4. Its therapeutic value is best known through GLP-2 analog development, but the native peptide itself is a real GI-relevant hormone.
Trefoil factor 2
TFF2 strengthens mucus-barrier repair and epithelial restitution after gastric injury in experimental systems, making it a well-known gastric-protective peptide.
