    Many peripheral substances, including ghrelin, induce neuronal activation in the brain. In the present study, we compared the effect of subcutaneously administered ghrelin and its three stable analogues, agonists: Dpr3ghr ([Dpr(N-octanoyl)3] ghrelin) (Dpr – diaminopropionic acid), YA GHRP-6 (Tyr-Ala-His-DTrp-Ala-Trp-DPhe-Lys-NH2), and JMV1843 (H-Aib-DTrp-D-gTrp-CHO) on the Fos expression in food intake-responsive brain areas such as the hypothalamic paraventricular (PVN) and arcuate (ARC) nuclei, the nucleus of the solitary tract (NTS), and area postrena (AP) in male C57BL/6 mice. Immunohistochemical analysis showed that acute SC administration of each of these substances, in dose (5 mg/kg b.w.), which induce strong food intake increase, elevated Fos protein expression in all brain areas studied.
