Dopaminergic neurons in the ventral tegmental area (VTA) are well known for their role in mediating the positive reinforcing effects of drugs of abuse. Here, we identify in rodents and humans a population of VTA dopamine neurons co-expressing corticotropin releasing factor (CRF). We provide further evidence in rodents that chronic nicotine exposure upregulates CRF mRNA in dopaminergic neurons of the posterior VTA, activates local CRF1 receptors, and blocks nicotine-induced activation of transient GABAergic input to dopaminergic neurons. Local downregulation of CRF mRNA and specific pharmacological blockade of CRF1 receptors in the VTA reversed the effect of nicotine on GABAergic input to dopaminergic neurons, prevented the aversive effects of nicotine withdrawal, and limited the escalation of nicotine intake. These results link the brain reward and stress systems within the same brain region in signaling the negative motivational effects of nicotine withdrawal.
