Interestingly, the GLP-1 receptor antagonist, des-His1-Glu9-exendin-4, attenuates LiCl-induced conditioned taste avoidance and anorexia by mechanisms involving the AP, NTS, and lateral parabrachial nucleus [15, 16] demonstrating several sites of action within the brain to modulate malaise and aversive mechanisms. This evidence concerns the gene GLP1R and Anorexia.
