Abstract：
:Our previous in vivo structure-activity studies suggested that the putative receptors mediating the effects of NPY and NPY2-36 on food intake and body temperature are pharmacologically different [17]. In the present study, we examined and compared dose-related effects of NPY and NPY2-36 on ad lib food intake and rectal temperature after administration into discrete hypothalamic nuclei of the rat. Results indicate that NPY and NPY2-36 have opposite effects on body temperature to those of NPY when injected in the preoptic area (POA): hypothermia and hyperthermia, respectively. When administered in the paraventricular nucleus (PVN), both increased body temperature. When injected into the third ventricle (3V), NPY produced a biphasic effect: hypothermia at low doses and hyperthermia at high doses. Similar effects were obtained with NPY2-36, but in an inverted dose-related fashion: hyperthermia at low and hypothermia at higher doses. In the arcuate nucleus (Arc), NPY induced a significant hypothermia whereas NPY2-36 had no effect. Finally, neither peptide affected body temperature when injected into the ventromedial (VMH) and perifornical (PeF) nuclei. Both NPY and NPY2-36 increased food intake after injection in all regions examined. In general, NPY was more potent and efficacious than NPY2-36. The present results clearly dissociate the effects of NPY on food intake and body temperature. Furthermore, the data support the hypothesis that the putative receptors underlying the effects of NPY and NPY2-36 on food intake are similar, whereas those mediating the effects on body temperature are pharmacologically different.
