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.
Secretin
Secretin is a classic GI hormone with extensive physiology literature and established diagnostic use. It remains important for studying pancreatic secretory function, biliary responses, and duodenal feedback.
