Definitions
- the present invention relates to the prophylactic or therapeutic use of GLP-2 derivatives and long-acting conjugates thereof for mucositis induced by radiotherapy, chemotherapy, or a combination thereof.
- Glucagon-like peptide-2 (GLP-2) is a peptide hormone composed of 33 amino acids produced by L-cells in the small intestine in response to ingested nutrients. GLP-2 induces mucosal growth in the small and large intestine, promotes growth of intestinal cells and crypt cells, and inhibits apoptosis. GLP-2 also increases the absorption of nutrients in the small intestine and decreases intestinal permeability. In addition, GLP-2 inhibits gastric emptying and gastric acid secretion, increases intestinal blood flow rate, and relaxes intestinal smooth muscle.
- GLP-2 has shown promising potential as a therapeutic agent in experimental models of various intestinal diseases and intestinal damage due to its features such as energy absorption and protection and activation of intestinal cell functions.
- GLP-2 As a hormone that regulates nutrient absorption, GLP-2 has potential as a treatment for short bowel syndrome (SBS).
- SBS short bowel syndrome
- SBS is caused by congenital or acquired causes such as bowel resection surgery and causes nutritional deficiencies due to a decrease in the absorption area of the small intestine. It was confirmed that GLP-2 enhances nutrient absorption and digestive tract absorption in a rodent experimental model with SBS (Ljungmann K et al., Am. J. Physiol. Gastrointest Liver Physiol., 2001, 281(3):G779-85). ).
