How GLP-1 Influences Brain Circuits that Control Eating
Updated
Abstract
Hypothalamic nuclei integrate signals from glucagon-like peptide-1 (GLP-1) to regulate feeding behavior and body weight.
- Endogenous GLP-1 is produced by preproglucagon neurons in the nucleus tractus solitarius.
- Pharmacological GLP-1 receptor agonists (GLP-1RAs) engage hypothalamic circuits that overlap with those activated by endogenous GLP-1.
- Mechanisms of action involve circuit redundancy and diverse modes of signal integration.
- Different GLP-1R ligands may have context-dependent effects on hypothalamic functions.
- Targeting central GLP-1 pathways could offer therapeutic potential for obesity treatment.
