Figure 1 3 Mechanism of action GLP-1RA mimics the role of GLP-1, a hormone released by the intestines after consumption of glucose-rich foods (12)
In this case, 5-h-fasted mice were intraperitoneally administered with 0.75 U of insulin (Sigma-Aldrich, MO, USA) per kg body weight, and blood glucose concentrations were determined before (0) and at 15, 30, 60, and 120 min after insulin injection
The scope of the review is intentionally selective rather than exhaustive, focusing on peptidereceptor systems that demonstrate biological plausibility, mechanistic coherence, and unmet therapeutic potential, yet lack approved therapeutic analogs or advanced clinical programs

Safety Monitoring To ensure safe escalation, clinical protocols monitored: Liver enzymes (ALT, AST) Kidney function Cardiovascular markers (blood pressure, lipids) Blood glucose in diabetic and non-diabetic participants So far, no significant cardiovascular safety issues have been reported, though long-term Phase 3 data will be critical before final conclusions can be made
In line with clinical data, GLP-1R agonism may also directly influence food preference through modulation of taste receptor expression
