A partly purified extract of the skin of the Australian frog Pseudophryne coriacea (PsC) evoked the release of [3H]acetylcholine [( 3H]ACh) and of [3H]5-hydroxytryptamine [( 3H]5-HT) from superfused rat cerebral cortex synaptosomes prelabeled with [3H]choline or [3H]5-HT, respectively. The PsC-evoked release of both transmitters was sensitive to tetrodotoxin and was strictly Ca2+-dependent. The release of [3H]5-HT caused by PsC was unaffected by the 5-HT uptake inhibitor citalopram. Activation of muscarinic autoreceptors by ACh or of serotonin autoreceptors by 5-HT depressed the PsC-evoked release of [3H]ACh or of [3H]5-HT, respectively. It is concluded that PsC elicits a Ca2+-dependent exocytotic-like transmitter release, possibly by opening Na+ channels in the presynaptic membrane.
