Research Overview
Insulin Degludec
Studies highlight prolonged action and lower glycemic variability compared with many other basal insulins. It is frequently used in research on ultra-long basal coverage and hypoglycemia reduction.
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.
