Abstract

A brief burst-suppressing isoflurane anesthesia has been shown to rapidly alleviate symptoms of depression in a subset of patients, but the neurobiological basis of these observations remains obscure. We show that a single isoflurane anesthesia produces antidepressant-like behavioural effects in the learned helplessness paradigm and regulates molecular events implicated in the mechanism of action of rapid-acting antidepressant ketamine: activation of brain-derived neurotrophic factor (BDNF) receptor TrkB, facilitation of mammalian target of rapamycin (mTOR) signaling pathway and inhibition of glycogen synthase kinase 3β (GSK3β). Moreover, isoflurane affected neuronal plasticity by facilitating long-term potentiation in the hippocampus. We also found that isoflurane increased activity of the parvalbumin interneurons, and facilitated GABAergic transmission in wild type mice but not in transgenic mice with reduced TrkB expression in parvalbumin interneurons. Our findings strengthen the role of TrkB signaling in the antidepressant responses and encourage further evaluation of isoflurane as a rapid-acting antidepressant devoid of the psychotomimetic effects and abuse potential of ketamine.

  • Isoflurane's antidepressant effects appear to be mediated via TrkB signaling and subsequent increases in dendritic spine density in the PFC and hippocampus.

    “these effects appear to be mediated via TrkB signaling and subsequent increases in dendritic spine density in the PFC and hippocampus (164, 165)”

    From Psychedelics and Other Psychoplastogens for Treating Mental Illness. (2021) · cites this paper as [164]

    The Discussion supports a role for TrkB signaling in isoflurane’s antidepressant-like behavioral effects. But the Results section, “Isoflurane does not regulate dendritic spine formation and turnover in the adult mouse cortex” (page not provided), reports no significant increase in spine density in the PFC or hippocampus, contrary to the claimed subsequent increase. (LLM, conf=0.91)

    Checked by a reasoning model — may be wrong.

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.
