Neuropeptide Y (NPY) is believed to regulate the normal eating behavior and body weight in rats via central mechanisms. We have investigated whether NPY, which stimulates food intake, may in turn be modified by the nutritional state of the animals. Thus the impact of food deprivation (FD) (48 h) and subsequent refeeding on the levels of NPY in discrete hypothalamic areas was examined in this study. The results showed site specific change in only 3 of 7 hypothalamic sites. A 5-fold increment in… CONTINUE READING
