Abstract

The origins of neuropeptide Y-like immunoreactive (NPYI) fibers in the paraventricular and dorsomedial hypothalamic nuclei of the rat were examined using immunohistochemistry. Destruction of the arcuate nucleus resulted in a marked decrease of NPYI fibers ipsilaterally in these nuclei, suggesting that most of NPYI fibers in these nuclei originate from NPYI neurons in the arcuate nucleus. These NPYI systems did not contain noradrenalin.

    Indeed, NPY ablation results in a similar compensatory upregulation of hypothalamic and hindbrain NPY expression and a resultant increase in food deprivation-induced food intake in other rodents [71,72]. Hindbrain NPY-producing neurons and Arc AgRP neurons project to the same hypothalamic nuclei (i.e. PVH) and may therefore contribute to, at the very least, the food deprivation-induced increases in food intake through similar mechanisms [73,74]. Although these results, together with mice and rat studies, clearly demonstrate an important role for the Arc in regulating ingestive behaviors, neuronal ablation prohibits interrogation of discrete neuronal populations.
