The anthelmintic praziquantel is a human serotoninergic G-protein-coupled receptor ligand

Abstract

Schistosomiasis is caused by infection with the flatworm Schistosoma, and praziquantel is the drug of choice for its treatment. Here, Chan and colleagues identify praziquantel as a ligand for the human serotoninergic 5-HT2B G-protein-coupled receptor, and reveal a function for praziquantel as a regulator of vascular tone in treated hosts.
