  • A comparative immunohistochemical study on a galanin-like peptide in the neuroEndocrine system of the alimentary canal of three species of siluriform catfishes
    Journal of Fish Biology, 2006
    Co-Authors: Giampaolo Bosi, Andrew P Shinn, Silvana Arrighi, Edi Simoni, Cinzia Domeneghini
    Abstract:

    Immunohistochemical examination of the galaninergic and the Diffuse Endocrine Systems of the alimentary canal of three catfish species, Ameiurus melas, Silurus glanis and Clarias gariepinus showed the presence of galanin-like immunoreactive Endocrine cells in the stomachs and the proximal intestines and a galanin-like immunoreactivity within the enteric intramural neurons. The three species differed notably in the relative abundance of galaninergic neurons of the digestive system. A galanin-like peptide was detected in a high number of nerve bundles and nerve fibres running through the exocrine parenchyma and the Endocrine islets of the pancreas of all three species. It is conceivable that the galaninergic system in these species plays a role in regulating gut muscle activity, in modulating mucosal secretive and absorptive processes, and in controlling pancreatic hormone secretion.

    Abstract:

    Immunohistochem. examn. of the galaninergic and the Diffuse Endocrine Systems of the alimentary canal of 3 catfish species, Ameiurus melas, Silurus glanis, and Clarias gariepinus, showed the presence of galanin-like immunoreactive Endocrine cells in the stomachs and the proximal intestines and a galanin-like immunoreactivity within the enteric intramural neurons. The 3 species differed notably in the relative abundance of galaninergic neurons of the digestive system. A galanin-like peptide was detected in a high no. of nerve bundles and nerve fibers running through the exocrine parenchyma and the Endocrine islets of the pancreas of all 3 species. It is conceivable that the galaninergic system in these species plays a role in regulating gut muscle activity, in modulating mucosal secretive and absorptive processes, and in controlling pancreatic hormone secretion.

  • the presence of a galanin like peptide in the gut neuroEndocrine system of lampetra fluviatilis and acipenser transmontanus an immunohistochemical study
    Tissue & Cell, 2004
    Co-Authors: Giampaolo Bosi, Andrew P Shinn, Silvana Arrighi, Luisa Giari, Cinzia Domeneghini
    Abstract:

    Galanin is a brain-gut neuropeptide present in the central and peripheral nervous Systems of vertebrates. In the present survey, the galaninergic and the Diffuse Endocrine Systems of the alimentary canal of the river lamprey, Lampetra fluviatilis, and the white sturgeon, Acipenser transmontanus, were studied by immunohistochemistry. The results show the presence of galanin-like immunoreactive Endocrine cells in the gut of L. fluviatilis. In addition, a galanin-like immunoreactivity was detected in enteric intramural neurons of both species. It is conceivable that the galaninergic system plays in both species a role in the regulation of the gut muscle contractility and in the modulation of mucosal secretive/absorptive processes. In A. transmontanus, the presence of galanin-like immunoreactive nerve fibres associated with components of the gut associated-lymphoid tissue is possibly correlated with a control of the defensive events at this site. The presence of a galanin-like immunoreactivity in the neuroEndocrine system of these two ancient fishes confirms the hypothesis on the early occurrence of this regulative molecule in the gastro-enteric system of vertebrates.

  • Neurotransmitters, neuromodulators, and neurotrophin receptors in the gut of pantex, a hybrid sparid fish (Pagrus major x Dentex dentex). Localizations in the enteric nervous and Endocrine Systems
    2001
    Co-Authors: Radaelli Giuseppe, Arrighi S, Domeneghini C, Castaldo L, Lucini C, Mascarello Francesco
    Abstract:

    The gut of Pantex, a sparid hybrid fish (Pagrus major x Dentex dentex) with a great potential importance for the Italian aquaculture, was histochemically and immunohistochemically investigated in order to evidence components of the intramural nervous and Diffuse Endocrine Systems. The general structural aspects of the intramural nervous system were shown by the Nissl-thionin staining. As in most other fish, it was only organized in the myenteric plexus. Acetylcholinesterase (AChE) activity was observed in both nerve cell bodies and terminals all along the gut. The NADPH-diaphorase reactivity too, possibly linked to the synthesis and release of nitric oxide, was present in nerve cell bodies and nerve terminals of the oesophagus, stomach and intestine. In addition, the intramural nervous system was shown to contain Trk (tyrosinekinase) receptors for neurotrophin, as evidenced by Trk A-, Trk B- and Trk C-like immunoreactivities, thus suggesting an involvement of neurotrophin in the function of this system. Trk B- and Trk C-like immunoreactivities were detected in epithelial Endocrine cells, too. The additional presence of serotonin- and metenkephalin-like immunoreactivities in numerous Endocrine cells in the epithelial layers of the stomach and intestine was showed
