Effect of pterois volitans (lionfish) venom on cholinergic and dopaminergic systems

Pterois volitans venom induces muscular fibrillation, which results from nerve transmission caused by the presence of acetylcholine (ACh). It also has cardiovascular effects that are due to its actions on muscarinic and nicotinic cholinergic receptors. In this study, we characterized the effects of P. volitans venom on nicotinic acetylcholine receptors (nAChRs) and dopaminergic neurons. After exposure to P. volitans venom, acetylcholinesterase...
