Abstract

Nicotine, the main psychoactive ingredient of tobacco, induces negative emotional symptoms during abstinence that contribute to a profound craving for nicotine. However, the neurobiological mechanisms underlying how nicotine produces dependence remains poorly understood. We demonstrate one mechanism for both the anxiety-like symptoms of withdrawal and excessive nicotine intake observed after abstinence, through recruitment of the extrahypothalamic stress peptide corticotropin-releasing factor (CRF) system and activation of CRF 1 receptors. Overactivation of the CRF–CRF 1 system may contribute to nicotine dependence and may represent a prominent target for investigating the vulnerability to tobacco addiction.

  • Nicotine withdrawal increases CRF in the CeA, and blockade of CRF1 receptors reduces nicotine withdrawal-induced anxiety-like behavior.

    “Nicotine withdrawal leads to an increase in CRF in the CeA, and blockade of CRF1 receptors diminishes nicotine withdrawalinduced anxiety-like behavior (George et al. 2007).”

    From Nicotine Withdrawal (2015) · cites this paper as George et al. 2007

  • CRF levels increase by more than 500% in the CeA after mecamylamine-precipitated nicotine withdrawal.

    “CRF levels increase by >500% in the CeA after nicotine withdrawal is precipitated with the nAChR antagonist mecamylamine [158].”

  • Injection of a CRF1 receptor antagonist into the CeA blunts anxiety-like behavior during nicotine withdrawal.

    “Injection of a CRF1 receptor antagonist into the CeA blunts anxiety-like behavior during nicotine withdrawal [158].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
