Coexistence of FMRFamide, met-enkephalin and serotonin in molluscan neurons.
1. Coexistence of FMRFamide, met-enkephalin and serotonin immunoreactivities was examined in Achatina fulica and Aplysia kurodai. 2. Coexistence of FMRFamide and serotonin was found in some neurons of the visceral, right parietal and pedal ganglia of Achatina fulica, and in the pedal ganglion of Aplysia kurodai. 3. In Achatina fulica, coexistence of FMRFamide and met-enkephalin was found in a neuron of the left parietal ganglion and that of met-enkephalin and serotonin was found in a giant neuron of the right parietal ganglion. 4. Based on these results, the biological significance of coexistence was discussed.
