In the present study we report the presence of acetylcholinesterase activity and gamma-aminobutyric acid binding sites in crude extracts of Dicrocoelium dendriticum. This indirectly demonstrates the presence of acetylcholine and GABA. The presence of these neurotransmitters could indicate the existence of two systems implicated in the neurotransmission of the Digenea.
Résumé
Cette étude rapporte la présence d'une activité anticholynestérasique et de sites de fixation de l'acide gamma-aminobutyrique (GABA) dans des extraits de Dicrocoelium dendriticum. Ceci prouve indirectement la présence d'acétylcholine et de GABA, et permet de poser l'hypothèse de l'existence de deux systèmes impliqués dans la neurotransmission des Digènes.
