Exendin-4能激活GLP-1受体，使该受体增加胰腺腺泡细胞(pancreatic acinar cells）的细胞内cAMP水平,但对VIP受体无效果。
Exendin-4 has been used as incretin mimetics for the treatment in HepG2 cells to exclude the influence of auxiliary material. It has also been used as an r (GLP-1R) agonist to exclude interference from auxiliary material.
Exendin-4 has been used for the treatment of ob/ob mouse model to determine the glucose and insulin concentrations and homeostasis model of assessment (HOMA), and for the determination of nuclear factor-κΒ (NF-κB) p65 level in macrophages treated with exendin-4. |

Exendin-4是一种39个氨基酸的多肽
Exendin-4 is an incretin mimetic peptide, which is composed of 39 amino acids. It is an analog of glucagon-like peptide 1 (GLP-1), and an insulinotropic agent, with a long half-life. It was originally isolated from the venom of Gila monster lizard called Heloderma suspectum. |
| 生化机理 |
Exendin-4 mimics the activity of mammalian incretin hormone glucagon-like peptide 1 (GLP-1), and thus, functions in the control of glucose. This includes the secretion of insulin in a glucose dependent manner, negative regulation of high glucagon secretion, and increased duration of stomach emptying. In type 2 diabetes patients, this peptide can be administered subcutaneously for glycemic control, when metformin is unable to produce adequate results. It promotes the neogeneration and proliferation of β-cells, and thus aids in the regeneration of pancreas. It acts as a ligand to exendin receptor, and leads to an elevation of acinar cell cAMP levels. |
