Neuropeptide Y in the specific hypothalamic nuclei of rats treated neonatally with monosodium glutamate
Brain Res Bull.
1990 Feb.
Abstract
Neuropeptide Y (NPY) concentration was determined by radioimmunoassay in selected hypothalamic regions microdissected from fresh brain slices of rats treated neonatally with monosodium glutamate (MSG). Fourteen weeks after MSG treatment, significant decreases in NPY concentration were found in the paraventricular nucleus (PVN) and arcuate nucleus (ARH), while there was no appreciable change in the ventromedial nucleus (VMH) and lateral area (LH). The decrease in NPY in the ARH-PVN system may contribute to the endocrine and metabolic disturbances seen in MSG-treated animals.
