Abstract

The nicotine in tobacco is thought to modulate neuronal systems regulating mood. Moreover, it appears possible that blockade rather than activation of beta2-containing (beta2*) nicotinic acetylcholine receptors (nAChRs) may lead to antidepressant-like effects. We used cytisine, a partial agonist of alpha4/beta2*nAChRs and a full agonist at alpha3/beta4*nAChRs, in several tests of antidepressant efficacy. Further, we used c-fos expression to identify potential neurobiological correlates of the antidepressant-like effects of cytisine. Cytisine had antidepressant-like effects in several animal models of antidepressant efficacy. In addition, immunohistochemical analyses indicated that cytisine could reduce c-fos immunoreactivity in the basolateral amygdala by approximately 50%. These data show that cytisine acts like classical antidepressants in rodent models of antidepressant efficacy. In addition, cytisine's ability to block alpha4/beta2*nAChRs may be responsible for its antidepressant-like properties, and these may be mediated through a reduction of neuronal activity in the basolateral amygdala. These studies also suggest that both antagonists and partial agonists of alpha4/beta2*nAChRs would be interesting targets for the development of novel antidepressant drugs.

  • Mecamylamine and DhβE have antidepressant-like properties in mice.

    “Mecamylamine and the competitive nicotinic antagonist DhβE also have antidepressant-like properties in mice (Caldarone et al., 2004; Mineur et al., 2007; Rabenstein et al., 2006).”

    From It is not “either/or”: Activation and desensitization of nicotinic acetylcholine receptors both contribute to behaviors related to nicotine addiction and mood (2008) · cites this paper as Mineur et al., 2007

    The Results (page not provided) report significantly reduced immobility after mecamylamine treatment in both the tail suspension and forced swim tests, supporting its antidepressant-like effects in mice. The passages from this paper do not report antidepressant-like effects of DhβE; a search for its full chemical name found no such result. (LLM, conf=0.90)

  • The α4/β2* subclass of nAChRs is necessary for the antidepressant-like effects of nicotinic antagonists.

    “the α4/β2* subclass of nAChRs is necessary for the antidepressant-like effects of nicotinic antagonists as demonstrated in KO mice and using selective pharmacological agents (Gatto et al., 2004; Mineur et al., 2007; Rabenstein et al., 2006).”

    From It is not “either/or”: Activation and desensitization of nicotinic acetylcholine receptors both contribute to behaviors related to nicotine addiction and mood (2008) · cites this paper as Mineur et al., 2007

    The Discussion reports that β2-subunit knockout mice do not show mecamylamine’s antidepressant-like effects, citing Rabenstein et al. (2006). It also says cytisine’s blockade of α4/β2* receptors may be critical to its effect. Those passages support a role for these receptors, but this paper does not demonstrate that the α4/β2* subclass is necessary for nicotinic antagonists’ antidepressant-like effects; its conclusion is hedged, and its knockout evidence is reported from another study. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Nicotinic partial agonists are effective in mouse models of antidepressant efficacy.

    “nicotinic partial agonists, that would be expected to decrease activity of acetylcholine at endogenous nAChRs when cholinergic tone is high but increase activity of nAChRs when cholinergic tone is low, are effective in mouse models of antidepressant efficacy (Mineur et al. 2007(Mineur et al. , 2009b(Mineur et al. , 2011a;;Rollema et al. 2009;Caldarone et al. 2011)”

    From Mechanisms of Nicotine Addiction (2021) · cites this paper as Mineur et al. 2007

  • The nicotinic partial agonist cytisine results in antidepressant-like effects in several behavioral paradigms in mice.

    “the nicotinic partial agonist cytisine results in antidepressant-like effects in several behavioral paradigms in mice (Mineur et al., 2007).”
  • Mecamylamine and cytisine decrease c-fos immunoreactivity in the basolateral amygdala, indicating a reduction of neuronal activity in this region.

    “Both mecamylamine and cytisine, in agreement with their antidepressant-like properties, decreased c-fos immunoreactivity in the basolateral amydgala, indicating a reduction of neuronal activity in this region (Mineur et al., 2007).”

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.
