Chemical mediation in Coelenterata.

E G Mendes

    Anais Da Academia Brasileira De Ciencias
    |January 1, 1976
    PubMed
    Summary

    This study found that the anthozoan Bunodosoma caissarum muscle preparations only responded to acetylcholine and body wall homogenates, challenging previous neurotransmitter theories in coelenterates.

    Area of Science:

    • Pharmacology
    • Neuroscience
    • Marine Biology

    Background:

    • Coelenterates, including anthozoans, possess a neuromuscular system.
    • Previous research on coelenterate neuromuscular junctions has yielded varied results regarding drug actions.

    Purpose of the Study:

    • To conduct a pharmacological survey of drug effects on Bunodosoma caissarum muscle preparations.
    • To critically review existing data on drug actions at the coelenterate neuromuscular junction.

    Main Methods:

    • Pharmacological testing of various drugs on isolated muscle preparations.
    • Analysis of responses to body wall homogenates and specific neurotransmitters/neuromodulators.

    Main Results:

    • Bunodosoma caissarum muscle preparations demonstrated sensitivity exclusively to acetylcholine and body wall homogenates.
    • Adrenaline, nor-adrenaline, tryptamine, serotonin, tyramine, histamine, L-glutamate, and GABA elicited no discernible response.

    Conclusions:

    • Acetylcholine appears to be a significant neurotransmitter in Bunodosoma caissarum.
    • The findings prompt a re-evaluation of the role of acetylcholine in coelenterate neurotransmission.
