NT69L blocks ethanol-induced increase of dopamine and glutamate levels in striatum of mouse

Neurosci Lett. 2011 Jan 10;487(3):322-4. doi: 10.1016/j.neulet.2010.10.048. Epub 2010 Oct 23.

Abstract

Recent study shows that NT69L, an analog of neurotensin (NT) (8-13), reduces ethanol consumption and preference in mice through modulation of neurotensin receptor subtype one. The current study showed that NT69L significantly decreased ethanol-induced increase of dopamine and glutamate levels in striatum of mouse. These data suggest that NT69L prevents ethanol consumption through the modulation of both dopaminergic and glutamatergic systems implicated in ethanol addiction. NT agonists may provide novel treatment for alcohol addiction.
