GLP-1 Peptides: Mechanism of Action

Overview

GLP-1 (glucagon-like peptide-1) receptor agonists are a class of incretin mimetics that have transformed metabolic research over the past decade. Originally investigated in the context of type 2 diabetes, this class is now studied extensively for weight regulation, cardiovascular outcomes, and neuroprotection.

Mechanism

GLP-1 binds to the GLP-1R receptor on pancreatic β-cells, triggering glucose-dependent insulin secretion. Secondary effects include slowed gastric emptying, suppressed glucagon release, and reduced appetite via central nervous system pathways.
