Exendin-4 significantly increased insulin level and phosphorylation of insulin receptor substrate 1 (IRS-1) in rat hippocampus, and could not change the status of tau phosphorylation without insulin in HT22 neurons, suggesting that insulin is required in reduction of tau hyperphosphorylation by GLP-1R agonists (154)
Albiglutide, dulaglutide, exenatide, liraglutide, lixisenatide, orforglipron and semaglutide used in the clinic are monoGLP-1RAs, tirzepatide acts not only on GLP1R, but also on glucose-dependent receptors of insulinotropic peptide (GIP), and retatrutide is a triple agonist of GLP-1, GIP and glucagon receptors
