GLP-2 action slide.gif (162277 bytes)Glucagon-like peptide-2 (GLP-2is a 33 amino acid peptide, co-secreted along with GLP-1 from intestinal endocrine cells in the small and large intestine

The function of GLP-2 was unrecognized for many years. The story starts with the observation that several human subjects with glucagonomas exhibit small bowel growth, as summarized in GLP-2 and Human Tumors. In 1996 GLP-2 administration in mice was shown to markedly increase small bowel growth in only a few days, principally due to hyperplasia of the villus epithelium
