One receptor, many organs, one coordinated signal
Liraglutide works by switching on a single receptor, the GLP-1 receptor, that happens to sit in several organs at once. The same molecule nudges the pancreas to release insulin only when glucose is high, tells the brain you are full, slows the stomach, and touches the heart and kidneys.
This unit maps where the receptor acts, then builds the incretin biology underneath: why the insulin boost is glucose-dependent, how the signaling cascade runs, and why appetite falls. It is the mechanistic core that the trial units then test against real outcomes.
