Ethanol Modulation of Glycine Receptor Mediated Currents in the Striatum

乙醇调节纹状体甘氨酸受体介导的电流

基本信息

项目摘要

DESCRIPTION (provided by applicant): Alcoholism is a chronic, cureless, and relapsing condition. Currently, the mechanisms by which alcohol exerts its intoxicating and reinforcing effects are not completely understood, but the development of alcohol seeking, dependence, withdrawal, and even acute intoxication involve, at least in part, the actions of alcohol on neural circuits involving the striatum. In addition, the actions of ethanol on a number of ion channels in the CNS have been established. Strychnine-sensitive glycine receptors (GlyRs) are among such targets of alcohol, and recent evidence demonstrates that GlyRs are expressed in forebrain regions including the striatum. Behavioral pharmacology studies suggest that GlyRs, specifically in the nucleus accumbens, are involved in alcohol consumption. However, the physiology of these particular GlyRs is not well defined, and the effects of ethanol action on native GlyRs in the striatum are not known. This project will specifically investigate GlyR physiology and ethanol pharmacology in the striatum using slice electrophysiology and molecular biology techniques. Our preliminary data suggest the presence of exogenously and tonically activated GlyR currents in the ventral striatum. Aim 1 will characterize GlyR mediated currents and ethanol modulation of GlyR function in the striatum (dorsal and ventral) to test the hypothesis that GlyRs are important mediators of neuronal excitability and that ethanol action at GlyRs may alter striatal neuron activity. Aim 2 will determine which GlyR ¿ subunits are involved in ethanol modulation of striatal GlyR currents using GlyR ¿ subunit knock-out (KO) mice to test the hypothesis that GlyRs containing ¿2 and/or ¿3 subunits may be particularly important for mediating the effects of striatal GlyR activation and ethanol modulation of GlyR function. Overall, findings from these experiments will provide novel insights into the effects of GlyR activation on neuronal excitabilit in the striatum and will contribute to a better understanding of how ethanol modulates striatal activity. Ultimately, by improving our knowledge of the mechanisms by which alcohol exerts its effects, new pharmacotherapies and enhanced treatment options can be developed for the treatment of alcoholism.
