Heterologous functional assay of the R. prolixus serotonin type 2b receptor (Rhopr5HTR2b) in CHOK1-aeq cells. (A) Dose-response curve demonstrating activity of serotonin and an agonist, alpha-methyl 5-HT, on the expressed Rhopr5HTR2b receptor. (B) Several serotonin receptor antagonists blocked the receptor-induced luminescent response, while gramine had no significant effect. (C) All other insect biogenic amines are inactive on the expressed Rhopr5HTR2b receptor.
