The therapeutic potential of oxytocin in alcohol related harms

Summary

Alcohol is the most widely abused recreational drug in the world and arguably the most harmful. Acute alcohol intoxication can result in disability or death through alcohol related injury or poisoning, while chronic use can lead to addiction, impaired mental health and physical health, disintegration of social and family ties, poverty and homelessness. The current treatment options for alcohol dependence are limited with both pharmacological and psychosocial interventions having questionable efficacy and uptake within the community. Novel, more efficacious interventions are clearly required. The GABAergic system is particularly sensitive to the effects of ethanol, with the delta subunit containing GABA-A receptors strongly implicated in the sedative, rewarding and possibly aggression-heightening effects of ethanol. Our recent work has shown that oxytocin can modulate the effects of alcohol at these receptors (Bowen et al., 2015. Oxytocin prevents ethanol actions at δ subunit-containing GABA-A receptors and attenuates ethanol-induced motor impairment in rats. PNAS), a finding which we wish to elucidate further in the current project. This project aims to improve our mechanistic understanding of how alcohol interacts with the brain to intoxicate, reward and disinhibit the individual.

Synopsis

The overall aim of this project is to extend our knowledge of oxytocin's interaction with ethanol at GABA-A receptors and the associated therapeutic potential of this effect in both in vitro and in vivo models.
