Background: It has been reported that dopamine D3 receptor (D3R) knockout mice display similar ethanol (EtOH) consumption compared to wild types. In addition, studies with D3R pharmacological targeting were inconclusive.Methods: In the current study, we used both gain- and loss-of-function approaches to test the effects of central D3R manipulation on voluntary alcohol intake and EtOH-induced...

Alcohol abuse is a major health, economic and social concern in modern societies, but the exact molecular mechanisms underlying ethanol addiction remain elusive. Recent findings show that small non-coding microRNA (miRNA) signaling contributes to complex behavioral disorders including drug addiction. However, the role of miRNAs in ethanol-induced conditioned-place preference (CPP) and voluntary...

Rationale: Dopamine D1 receptor (D1R) signaling has been associated to ethanol consumption and reward in laboratory animals.Objectives: Here, we hypothesize that this receptor, which is located within the nucleus accumbens (NAc) neurons, modulates alcohol reward mechanisms.Methods: To test this hypothesis, we measured alcohol consumption and ethanol-induced psychomotor sensitization and...
