Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist used by researchers to study incretin pathways that influence insulin secretion, appetite regulation, and glycemic control. This article explores the GLP-1 receptor signaling cascade, its role in energy homeostasis, and how semaglutide provides a tool for investigating these mechanisms in vitro. We discuss how researchers use semaglutide to examine pancreatic beta-cell function, neuronal satiety pathways, and metabolic regulation.
