Research Overview
Exendin-4
Exendin-4 helped establish GLP-1 receptor biology in diabetes and remains a classic beta-cell protective peptide. Preclinical studies show reduced beta-cell apoptosis, improved insulin content, and better islet function under metabolic stress.
Glucagon
Clinical and emergency medicine use is well established for severe hypoglycemia, with newer stable formulations improving ease of administration.
