As GLP-1Rs are expressed in multiple brain regions, and GLP-1RAs such as liraglutide and lixisenatide can penetrate the blood-brain barrier, liraglutide and exendin-4 can be vagus-dependent or independent in the suppression of the food intake (176)

Integrated Metabolic Modeling: Supports studies evaluating coordinated endocrine signaling rather than isolated receptor activation

Despite this shared mechanism, the two receptors exhibit distinct expression patterns and physiological roles that are genuinely complementary: When both axes are activated concurrently, the cAMP response in pancreatic -cells exceeds that of either agonist alone, indicating synergistic rather than merely additive intracellular signaling

Taken as a once daily pill, the drug was much more convenient than exenatide which required administration by injection (Cordes)
