    Giuliana Zega
    Dipartimento di Biologia, Sez Zoologia S N, Universit Statale di Milano, Milan, Italy
    Int J Dev Biol 51:307-13. 2007
    ..Results from this work showed that 5-HT could stimulate metamorphosis in E. racemosum planulae in the presence of a natural inducer. A mechanism by which this neurotransmitter could act in this phase is proposed...
  2. ncbi Dopamine and serotonin modulate the onset of metamorphosis in the ascidian Phallusia mammillata

    Dipartimento di Biologia, Universita di Milano, Via Celoria 26, I 20133, Milano, Italy
    Dev Biol 282:246-56. 2005
    ..So, it is possible to suppose that dopamine signaling delayed metamorphosis while serotonin signaling triggers it. We propose a mechanism by which these neurotransmitters may modulate the timing of metamorphosis in larvae...

    J Comp Neurol 506:489-505. 2008
    ..intestinalis nervous system and that it can signal through GABA(B) receptors both pre- and postsynaptically to modulate different sensory inputs and subsequent swimming activity...
  4. ncbi Development of swimming behaviour in the larva of the ascidian Ciona intestinalis
    Giuliana Zega
    Neurobiology Laboratory Stazione Zoologica Anton Dohrn, Villa Comunale I 80121 Naples, Italy
    J Exp Biol 209:3405-12. 2006
    ..Our results provide a starting point for future studies that aim to characterize the nervous control of ascidian locomotion, in wild-type or mutant larvae...

    Department of Biology, sez Zoologia S N 7B, University of Milan, Via Celoria 26, 20133 Milan, Italy
    Dev Genes Evol 213:187-92. 2003
    ..These results suggest that 5-HT plays a role in the development of the neural system in ascidians and its action is mediated by receptors similar to the members of the 5-HT(1A) receptor subtype of mammals...
  6. ncbi Developmental expression of tryptophan hydroxylase gene in Ciona intestinalis
    Roberta Pennati
    Dipartimento di Biologia, Universita di Milano, Via Celoria 26, 20133 Milano, Italy

    Aquat Toxicol 91:255-61. 2009
    ..It is likely that the fungicidal teratogenic mechanism involved RA signalling but that its effects on ascidian development depend on a more complex mechanism...

    Aquat Toxicol 79:205-12. 2006
    ..Ascidians proved to be good models to study the toxic effects of pesticides since they offered both the convenience of working with an invertebrate species and the tissue sensitivity to chemical compound comparable to vertebrates...

    Silvia Groppelli
    Department of Biology, University of Milano, Via Celoria 26, 20133 Milano, Italy
    Environ Toxicol Pharmacol 23:265-71. 2007
    ..These anomalies resulted similar to those induced by retinoic acid (RA) treatment. Thus, it could be hypothesized that FLUCO and RA may act with a similar pathogenic mechanism in ascidian larvae, as it has been proposed for mammals...

    Environ Toxicol Pharmacol 29:24-31. 2010
    ..For its sensitivity to paraquat and its simple chordate body plan, ascidian larva is a promising animal model to further investigate the molecular mechanism of paraquat neurotoxicity...
