Glucagon-like peptide-2

Glucagon-like peptide-2 (GLP-2) is a 33-amino-acid gut hormone produced from proglucagon in intestinal L cells and co-released with GLP-1. Acting through the GLP-2 receptor, it promotes intestinal growth, mucosal integrity and nutrient absorption. This page is educational and not medical advice.

Overview

Glucagon-like peptide-2 (GLP-2) is a 33-amino-acid gut hormone produced from proglucagon in intestinal L cells and co-released with GLP-1. Acting through the GLP-2 receptor, it promotes intestinal growth, mucosal integrity and nutrient absorption. This page is educational and not medical advice.

Source & context

Biological / chemical source: Secreted by intestinal L cells (proglucagon gene)

Primary research or clinical context: Intestinal physiology and short-bowel research

Origin and actions

GLP-2 is cleaved from the same proglucagon precursor as GLP-1 and secreted after meals. It increases intestinal villus height and crypt depth, enhances barrier function and blood flow, and reduces bone breakdown, with a short native half-life because of DPP-4 degradation.

Therapeutic analog

The DPP-4-resistant analog teduglutide substitutes glycine for alanine at position 2, extending its half-life, and is approved for short bowel syndrome. This makes GLP-2 a well-characterized model for intestinal-adaptation and gut-hormone research.
