Moreover, the widespread tissue presence of GLP-1R has witnessed new physiological roles for GLP-1 beyond glycaemia and satiety such as cardioprotection ( (118, 119); Figure 3), enhancing bone mass and strength in preclinical models of T2DM (120), and is thought to play an important role in enhancing cognition ( (121); Figure 3). The gene discussed is GLP1R; the disease is type 2 diabetes mellitus.
