Tirzepatide activates both GLP-1 and GIP receptors simultaneously, creating a more powerful appetite suppression and metabolic effect than semaglutide's single GLP-1 pathway
Furthermore, dual-action compounds engaging GLP-1 combined with glucose-dependent insulinotropic polypeptide (GIP) or glucagon pathways, alongside triple agonists incorporating all three receptors activation, have exhibited enhanced therapeutic potential
This sophisticated mechanism has made it a cornerstone of many ongoing studies exploring metabolic disorders
Immunostaining Deparaffinized tissues were unmasked using antigen unmasking solution (Vector Laboratories, Burlingame, CA, USA) in a microwave oven
Exploratory endpoints reported included changes from baseline to week 104 in glycemic category, antihypertensive medication use, and lipid-lowering medication use
