Influence of cannabinoid receptor ligands on 5-HT (30 μM; −100 mV)-induced currents in patches of HEK 293 cells stably transfected with the h5-HT3A receptor cDNA. (a) Concentration-dependent inhibition by the cannabinoid receptor agonist WIN55,212-2 in the absence and presence of the CB1 receptor antagonist SR141716A (at 1 μM) and lack of inhibition by the enantiomer WIN55,212-3 and by SR141716A alone. (b) Concentration-dependent inhibition of 5-HT (30 μM; −100 mV)-induced currents by various cannabinoid receptor ligands. Drugs were present 3 min before, during and after the 2 s 5-HT pulse. Shown are means±s.e.m. of 3–6 different patches.
