Enhanced AMPA Receptor Trafficking Mediates the Anorexigenic Effect of Endogenous Glucagon-like Peptide-1 in the Paraventricular Hypothalamus

0

Liu et al. show that GLP-1 signaling in PVN suppresses food intake and may prevent obesity. The molecular mechanism underlying the GLP-1 function in the PVN is via AMPA receptor subunit-GluA1 phosphorylation and subsequent membrane trafficking in a PKA-dependent pathway.
