Localization of Neuropeptide Y-like Immunoreactive Structures in the Brain of the Pejerrey, Odontesthes bonariensis (Teleostei, Atheriniformes)
The aim of this study was to determine the distribution of Neuropeptide-Y (NPY) immunoreactive neurons and fibres in the brain and pituitary of Odontesthes bonariensis by immunohistochemical methods. A wide distribution of immunoreactive NPY (ir-NPY) cells and fibres in the forebrain and midbrain wa...

| 520 | |a The aim of this study was to determine the distribution of Neuropeptide-Y (NPY) immunoreactive neurons and fibres in the brain and pituitary of Odontesthes bonariensis by immunohistochemical methods. A wide distribution of immunoreactive NPY (ir-NPY) cells and fibres in the forebrain and midbrain was observed. A prominent ir-NPY nucleus was found in the ventral telencephalon and other ir-NPY cells groups were recognized at the dorso-medial telencephalon. The diencephalon showed ir-NPY cells in the Nucleus entopeduncularis, the Nucleus preopticus periventricularis and in the Nucleus lateralis tuberis. Ir-NPY fibres were conspicuous in the preoptic region and the hypothalamus. There were also numerous ir-NPY fibres at the epithalamic level running ventrally to the hypothalamus and the pituitary stalk. At the rhomboencephalic level, the ir-NPY neurons were observed in the Locus coeruleus. Double-labelled immunostaining showed a close association between ir-NPY fibres that reach the adenohypophysis and growth hormone (GH)- and gonadotropin (GtH)-expressing cells. Although our results exhibit some relevant differences when compared to other fish groups, they support the existence of a conserved NPY system in teleosts. | ||

Localization of Neuropeptide Y-like Immunoreactive Structures in the Brain of the Pejerrey, Odontesthes bonariensis (Teleostei, Atheriniformes) |
| abstract |
The aim of this study was to determine the distribution of Neuropeptide-Y (NPY) immunoreactive neurons and fibres in the brain and pituitary of Odontesthes bonariensis by immunohistochemical methods. A wide distribution of immunoreactive NPY (ir-NPY) cells and fibres in the forebrain and midbrain was observed. A prominent ir-NPY nucleus was found in the ventral telencephalon and other ir-NPY cells groups were recognized at the dorso-medial telencephalon. The diencephalon showed ir-NPY cells in the Nucleus entopeduncularis, the Nucleus preopticus periventricularis and in the Nucleus lateralis tuberis. Ir-NPY fibres were conspicuous in the preoptic region and the hypothalamus. There were also numerous ir-NPY fibres at the epithalamic level running ventrally to the hypothalamus and the pituitary stalk. At the rhomboencephalic level, the ir-NPY neurons were observed in the Locus coeruleus. Double-labelled immunostaining showed a close association between ir-NPY fibres that reach the adenohypophysis and growth hormone (GH)- and gonadotropin (GtH)-expressing cells. Although our results exhibit some relevant differences when compared to other fish groups, they support the existence of a conserved NPY system in teleosts. |
