5-HT3 receptors and central effects of ethanol.
This review discusses recent experimental findings in serotonin-3 (5-HT3) receptors and ethanol (EtOH) research. The role of these receptors in central effects of EtOH including the effects of 5-HT3 agonists and antagonists on EtOH intake, rewarding and aversive properties of EtOH and EtOH interoceptive cue is reviewed. It is now recognized that 5-HT3 receptors while involved in EtOH intake, EtOH tolerance and withdrawal and rewarding mechanisms do not play an important role in aversive effects of EtOH and EtOH discriminative stimulus. 5-HT3 receptors involved in EtOH consumption are supposedly located on dopaminergic neurons in the nucleus accumbens.
