Research Overview
Glucagon
Clinical and emergency medicine use is well established for severe hypoglycemia, with newer stable formulations improving ease of administration.
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.
