Description
This finding demonstrates the robust activity of tirzepatide at the alpha cell GIPR that outweighs inhibitory actions produced by GLP-1R agonism and provides additional evidence that tirzepatide has important activity at the GIPR in human islets
This improved sensitivity may result from lower glucagon levels associated with enhanced insulin action due to improved metabolic control
The study is observational and cannot establish causation
