Abstract

Background Chronic exposure to nicotine elicits physical dependence in smokers, yet the mechanism and neuroanatomical bases for withdrawal symptoms are unclear. As in humans, rodents undergo physical withdrawal symptoms after cessation from chronic nicotine characterized by increased scratching, head nods, and body shakes.Results Here we show that induction of physical nicotine withdrawal symptoms activates GABAergic neurons within the interpeduncular nucleus (IPN). Optical activation of IPN GABAergic neurons via light stimulation of channelrhodopsin elicited physical withdrawal symptoms in both nicotine-naive and chronic-nicotine-exposed mice. Dampening excitability of GABAergic neurons during nicotine withdrawal through IPN-selective infusion of an NMDA receptor antagonist or through blockade of IPN neurotransmission from the medial habenula reduced IPN neuronal activation and alleviated withdrawal symptoms. During chronic nicotine exposure, nicotinic acetylcholine receptors containing the β4 subunit were upregulated in somatostatin interneurons clustered in the dorsal region of the IPN. Blockade of these receptors induced withdrawal signs more dramatically in nicotine-dependent compared to nicotine-naive mice and activated nonsomatostatin neurons in the IPN.Conclusions Together, our data indicate that therapeutic strategies to reduce IPN GABAergic neuron excitability during nicotine withdrawal, for example, by activating nicotinic receptors on somatostatin interneurons, may be beneficial for alleviating withdrawal symptoms and facilitating smoking cessation.

  • Lidocaine infusion into the MHb to inhibit signaling significantly blocks somatic symptoms from both mecamylamine-precipitated and spontaneous nicotine withdrawal.

    “Furthermore, lidocaine infusion into the MHb to inhibit signaling significantly blocks the manifestations of somatic symptoms resulting from both mecamylamine-precipitated and spontaneous induction of nicotine withdrawal (Zhao-Shea et al. 2013).”

    From Nicotine Withdrawal (2015) · cites this paper as Zhao-Shea et al. 2013

    The Results section (“Glutamate release from MHb-IPN afferents is necessary for somatic nicotine withdrawal signs”; page unavailable) reports that lidocaine infusion into the MHb significantly blocked somatic signs during spontaneous withdrawal. For mecamylamine-precipitated withdrawal, it reports reduced IPN neuronal activation measured by c-Fos, not a significant reduction in somatic symptoms. (LLM, conf=0.91)

  • Through the MHb-IPN projection, the MHb releases acetylcholine, substance P, and glutamate onto the IPN.

    “Through this projection, the MHb releases acetylcholine (ACh), substance P (SP), and glutamate onto the IPN (Zhao-Shea et al. 2013).”

    From Nicotine Withdrawal (2015) · cites this paper as Zhao-Shea et al. 2013

    The Results section, “Glutamate release from MHb-IPN afferents is necessary for somatic nicotine withdrawal signs,” says that cholinergic afferents from the MHb also release glutamate into the IPN. The Discussion likewise describes cholinergic input and glutamate release, but our copy does not say that this projection releases substance P. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Infusion of an α3β4* nAChR-selective antagonist into the IPN elicits somatic withdrawal signs in nicotine-naïve mice and more total symptoms in chronically nicotine-treated mice.

    “Additionally, infusion of an α3β4* nAChR-selective antagonist into the IPN elicited somatic withdrawal signs in nicotine-naïve mice and an even greater number of total symptoms in mice chronically treated with nicotine (Zhao-Shea et al. 2013).”

    From Nicotine Withdrawal (2015) · cites this paper as Zhao-Shea et al. 2013

  • After precipitated nicotine withdrawal in wild-type mice, there are elevated markers of neuronal activation in GABAergic IPN cells.

    “Following precipitated nicotine withdrawal in WT mice, there are elevated markers of neuronal activation in GABAergic IPN cells (Zhao-Shea et al. 2013).”

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.
