GLP-1 Receptor Pathway - Reduces hunger drive centrally (hypothalamus, brainstem) - Decreases the reward value of food (mesolimbic system) - Enhances glucose-dependent insulin secretion - Slows gastric emptying Amylin Receptor Pathway - Induces satiety through the area postrema and NTS - Activates POMC neurons (pro-satiety) and suppresses NPY/AgRP neurons (pro-hunger) in the arcuate nucleus - Additional gastric emptying delay through distinct neural circuits - Suppresses post-prandial glucagon secretion - May contribute to leptin resensitization The combination of these two pathways produces what researchers describe as broader modulation of neuroendocrine appetite control meaning amycretin hits more of the biological switches that drive eating behavior than a GLP-1-only drug can reach

Alternatives if Wegovy is too expensive If youre paying out of pocket and Wegovy is unaffordable, consider: Compounded semaglutide : Offered by some weight loss clinics for $250$400/month Zepbound (tirzepatide) : Newer GLP-1 option with similar pricing but different insurance coverage Phentermine or Contrave : Older appetite suppressants, much cheaper (~$30$100/month) GLP-1 programs at urgent care clinics : May offer bundled pricing for meds, labs, and check-ins Urgent care providers can help you compare your options and start safely the same day

Trypsin activity was quenched by adding 200 L of MEF medium (10% FBS in DMEM), and the cell suspensions were centrifuged at 300 g
