Neurotensin is a tridecapeptide that participates in regulation of dopaminergic pathways implicated in nicotine addiction. Previously, we showed that one of our brain-penetrating neurotensin analogs, NT69L, blocks nicotine-induced locomotor sensitization. The present work demonstrates that NT69L blocks both the initiation and the expression of sensitization. In addition chronic NT69L administration blocked the acute effects of nicotine on norepinephrine and serotonin in prefrontal cortex.
