Nesfatin/NUCB2 is expressed in the appetite-control hypothalamic nuclei such as paraventricular nucleus (PVN), arcuate nucleus (ARC), supraoptic nucleus (SON) of hypothalamus, lateral hypothalamic area (LHA), and zona incerta in rats. Nesfatin-1 immunoreactivity was also found in the brainstem nuclei such as nucleus of the solitary tract (NTS) and Dorsal nucleus of vagus nerve.
