Effects of ethanol on the function of Ca(2+)-activated Cl- channels activated by G protein-coupled serotonin (5-hydroxytryptamine, (5-HT)1c) and muscarinic M1 cholinergic receptors were studied in Xenopus oocytes expressing mouse whole-brain mRNA. Ethanol (25-200 mM) inhibited currents evoked by both 5-HT and acetylcholine (ACh), in a concentration-dependent manner. The maximal effect was obtained with 150 mM ethanol, which produced 65 and 49% inhibition of 5-HT and ACh responses, respectively… CONTINUE READING
