Glucagon-like peptide-2

Glucagon-like peptide-2 (GLP-2) is a protein and hormone that is synthesized and released by the intestinal cells in the human body. It is one of the two forms of Glucagon-like peptides, the other being GLP-1. GLP-2 plays a crucial role in the regulation of nutrient absorption, intestinal growth and function, and maintenance of the intestinal mucosa.

Structure

GLP-2 is a 33-amino acid peptide hormone that is derived from the proglucagon gene. The structure of GLP-2 is characterized by a single disulfide bond which is essential for its biological activity.

Function

GLP-2 is primarily known for its role in the growth and maintenance of the intestinal lining. It promotes the growth of the intestinal epithelium and enhances the absorption of nutrients by increasing the surface area of the intestinal mucosa. GLP-2 also reduces intestinal permeability and inflammation, thereby playing a role in the maintenance of gut barrier function.

In addition to its effects on the intestine, GLP-2 has been shown to influence bone metabolism, appetite regulation, and glucose homeostasis. However, the mechanisms underlying these effects are not fully understood.

Clinical significance

GLP-2 has been studied for its potential therapeutic applications in various gastrointestinal diseases. Synthetic GLP-2 analogs, such as Teduglutide, have been developed and approved for the treatment of short bowel syndrome and Crohn's disease. Research is ongoing to explore the potential of GLP-2 in the treatment of other conditions, such as intestinal failure, celiac disease, and chemotherapy-induced mucositis.
