GLP-2: what do we know? What are we going to discover?

Area of Science:

• Gastroenterology
• Neuroendocrinology
• Metabolism

Background:

• Glucagon-like peptide 2 (GLP-2) is an intestinal peptide hormone.
• GLP-2 acts via the GLP-2 receptor (GLP-2R) located on enteric neurons, not intestinal epithelium.
• GLP-2 is recognized for its gut-trophic effects and is gaining attention for short bowel syndrome (SBS) treatment.

Purpose of the Study:

• To review the role of GLP-2 in modulating gastrointestinal function.
• To highlight recent advancements and the innovative aspects of GLP-2 research.
• To explore the emerging involvement of GLP-2 in glucose homeostasis.

Main Methods:

• Literature review focusing on neuroendocrine peptides, particularly GLP-2.
• Analysis of studies investigating GLP-2's mechanism of action and physiological roles.
• Synthesis of recent findings on GLP-2R signaling and therapeutic applications.

Main Results:

• GLP-2 exerts its effects indirectly through the enteric nervous system.
• GLP-2R agonists are approved for short bowel syndrome, demonstrating clinical relevance.
• Emerging evidence suggests a role for GLP-2 in regulating glucose metabolism.

Conclusions:

• GLP-2 is a key neuroendocrine peptide involved in gastrointestinal regulation.
• The indirect action of GLP-2 via GLP-2R presents unique therapeutic opportunities.
• Further research into GLP-2's multifaceted roles, including glucose homeostasis, is warranted.
