Abstract

The alpha6 nicotinic acetylcholine receptor (nAChR) subunit is involved in nicotine-stimulated dopamine release in the striatum. It is expressed in brain regions and coexpressed with nAChR subtypes implicated in nicotine dependence behaviors; hence, this subunit may play a role in nicotine dependence. Using the alpha6-selective antagonist alpha-conotoxin H9A;L15A (MII[H9A;L15A]), we determined the role of alpha6* nAChRs in the pharmacological and behavioral effects of nicotine. We measured effects of pretreatment with MII[H9A;L15A] on analgesia, locomotion, and body temperature after a single injection of nicotine. Effects of MII[H9A;L15A] on nicotine reward were measured using the conditioned place preference (CPP) paradigm. We further measured physical (somatic signs and hyperalgesia) and affective [anxiety-related behavior and conditioned place aversion (CPA)] nicotine withdrawal behaviors after extended nicotine exposure. Results showed that MII[H9A;L15A] did not block acute nicotine effects on the behaviors measured. Conversely, MII[H9A:l15A] blocked the expression of nicotine CPP, as well as withdrawal-associated CPA and anxiety-related behavior in the elevated plus maze, but not withdrawal-induced somatic signs or hyperalgesia. These results suggest a role for the alpha6 nAChR subunit in nicotine reward and affective nicotine withdrawal but not acute nicotine-induced or physical withdrawal behaviors.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • α6 nAChR subunits have a selective role in the affective manifestations of withdrawal and do not influence somatic withdrawal symptoms.

    “There was no influence on the somatic symptoms of withdrawal, suggesting a selective role for α6 nAChR subunits in the affective manifestations of withdrawal (Jackson et al. 2009).”

    From Nicotine Withdrawal (2015) · cites this paper as Jackson et al. 2009

  • α6* nAChRs have a documented role in withdrawal-induced conditioned place aversion.

    “and there is a documented role for α6* nAChRs in withdrawal-induced CPA (Jackson et al. 2009).”

    From Nicotine Withdrawal (2015) · cites this paper as Jackson et al. 2009

  • β2-containing and α6-containing nAChRs are necessary for conditioned place aversion, but α5 and α7 do not affect it.

    “Pharmacological studies in nAChR null mice indicate that β2-containing and α6-containing nAChRs are necessary for CPA, but neither the α5, nor the α7 subunits affect CPA behavior [170, 172, 189].”

    From Mechanistic insights into nicotine withdrawal (2011) · cites this paper as [172]

  • Somatic signs of withdrawal are preserved in mice lacking β2 or α6 nAChR subunits.

    “Interestingly, somatic signs of withdrawal are preserved in mice lacking the β2 or the α6 nAChR subunits [11, 172]”

    From Mechanistic insights into nicotine withdrawal (2011) · cites this paper as [172]

  • β2 and α6 nAChR subunits are necessary for increased anxiety during withdrawal, whereas α5 and α7 may not be required.

    “So far, it has been established that the β2 and α6 nAChR subunits are necessary for increased anxiety during withdrawal [170, 172], whereas, α5 and α7 may not be required [170].”

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.
