Research Overview

Larazotide

Clinical and translational studies suggest larazotide can reduce antigen passage across the epithelium and improve gut barrier function. It is one of the better-known peptides for intestinal permeability and barrier-focused gastrointestinal therapy.

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.
