Taurine enhances voluntary alcohol intake and promotes anxiolytic-like behaviors in rats.

Taurine is an amino acid usually added to energy drinks. In rodents, acute taurine administration decreases voluntary alcohol intake, and subchronic administration restores different behavioral features impaired by alcohol withdrawal. In the present study, we evaluated the effects of chronic taurine treatment on voluntary alcohol consumption and changes in behavioral parameters in rats.

Combined use of alcohol and cigarette increases locomotion and glutamate levels in the cerebrospinal fluid without changes on GABA or NMDA receptor subunit mRNA expression in the hippocampus of rats.

Interactions on neurotransmitter systems in the reward pathways may explain the high frequency of combined use of alcohol and cigarettes in humans. In this study, we evaluated some behavioral and neurochemical changes promoted by chronic exposure to alcohol and cigarette smoke in rats. Adult rats were administered with 2 g/kg alcohol (v.

Correlations between subunits of GABA and NMDA receptors after chronic alcohol treatment or withdrawal, and the effect of taurine in the hippocampus of rats.

Chronic use of alcohol and its withdrawal impairs the delicate balance between GABAergic and glutamatergic systems. This imbalance includes changes in GABA receptors - importantly in GABA subtypes - and glutamate receptors, especially in NMDA subtypes. A better comprehension of the different roles of GABAR and NMDAR subunits could be helpful to define new strategies to counteract the deleterious effects observed during alcohol withdrawal.
