Neuron

A brain circuit that limits alcohol reward and helps liraglutide reduce drinking in mice

Updated

Abstract

Systemic administration of the GLP-1R agonist liraglutide decreased alcohol intake by reducing dopamine release in the nucleus accumbens.

  • GLP-1R signaling in the dorsal lateral septum (dLS) is linked to regulation of alcohol consumption.
  • Liraglutide decreased dopamine release in response to ethanol exposure.
  • Alcohol consumption was associated with suppressed activity of dLS neurons.
  • Liraglutide prevented alcohol-induced suppression of calcium signals in dLS neurons.
  • Inactivation of dLS neurons led to increased alcohol consumption and negated the effects of liraglutide.
  • Local inhibitory projections from dLS neurons to specific neurons in the ventral lateral septum were identified as important in regulating alcohol intake.
