Localisation of gamma aminobutyric acid (GABA)-like immunoreactivity in the echinoderm Asterias rubens.

Newman SJ , Thorndyke MC .


???displayArticle.abstract???
Gamma amino butyric acid (GABA) is believed to be the principal inhibitory neurotransmitter in the mammalian central nervous system, a function that has been extended to a number of invertebrate systems. We have used a specific antiserum raised against GABA to demonstrate GABA-like immunoreactivity in the radial nerve cord (RNC), tube feet and the digestive system of the asteroid Asterias rubens. In the RNC, immunoreactivity was restricted to ectoneural fibres and cell bodies while in the tube feet fibres were revealed in the basal nerve ring and longitudinal nerve. In the gut, extensive labelling was apparent in the basi-epithelial plexus as well as in mucosal perikarya.
