We studied the long term effects of a single exposure to immobilization stress (IS) (1 h) on the expression of anorexigenic (Pro-opiomelanocortin: POMC and cocaine amphetamine related transcript: CART) and orexigenic (neuropeptide Y:NPY, Agouti related peptide: AgRP) factors in hypothalamus and dorso vagal complex (DVC). We showed, by using RT-PCR that in(More)
The aim of the present investigation was to determine a detailed mapping of neurotensin (NT) in the human hypothalamus, the brain region involved in neuroendocrine control. For this, we investigated the presence and the distribution of neurotensin binding sites in the human hypothalamus, using an in vitro quantitative autoradiography technique and the(More)
The dorsal vagal complex (DVC) is the satiety reflex-integrating center of adult mammals. Immobilization stress (IS) is known to elicit anorexia and to up-regulate BDNF expression in adult rat forebrain; intra-DVC delivery of BDNF was shown to elicit anorexia. Therefore, we addressed here whether IS would increase BDNF signaling in rat DVC by using PCR and(More)
We have studied the developmental patterns of vasoactive intestinal polypeptide (VIP) binding sites in the human hypothalamus. VIP recognition sites were widely distributed throughout the rostrocaudal extent of the hypothalamus. VIP binding was generally low in the fetal and neonatal periods and a tendency in increasing densities was observed during(More)
The aim of the present study was to determine a detailed mapping of neurotensin (NT) in the human hypothalamus, during the first postnatal year using an in vitro quantitative autoradiography technique and the selective radioligand monoiodo-Tyr3-NT. Ten human postmortem hypothalami obtained from control neonates and infants (aged from 2 h to 1 year of(More)
Somatostatin has been reported to modulate GABA A receptor complex in many brain structures. This study was conducted to investigate somatostatin modulation of the GABA A receptor binding in several rat diencephalic structures, focusing primarily on the thalamus, as this structure plays important roles. Animals were assigned to control conditions. Changes(More)
