Abstract

Ketamine is a non-competitive antagonist to the phencyclidine site of N-methyl-d-aspartate (NMDA) receptor. Clinical findings point to a rapid onset of action for ketamine on the treatment of major depression. Considering that classic antidepressants may take long-lasting time to exhibit their main therapeutic effects, the present study aims to compare the behavioral effects and the BDNF hippocampus levels of acute administration of ketamine and imipramine in rats. To this aim, rats were acutely treated with ketamine (5, 10 and 15 mg/kg) and imipramine (10, 20 and 30 mg/kg) and animal behavioral was assessed in the forced swimming and open-field tests. Afterwards, BDNF protein hippocampal levels were assessed in imipramine- and ketamine-treated rats by ELISA-sandwich assay. We observed that ketamine at the doses of 10 and 15 mg/kg, and imipramine at 20 and 30 mg/kg reduced immobility time compared to saline group, without affecting locomotor activity. Interesting enough, acute administration of ketamine at the higher dose, but not imipramine, increased BDNF protein levels in the rat hippocampus. In conclusion, our findings suggest that the increase of hippocampal BDNF protein levels induced by ketamine might be necessary to produce a rapid onset of antidepressant action.

  • Acute ketamine that induces an antidepressant effect increases BDNF protein levels in the hippocampus.

    “This data is in agreement with prior work showing that acute ketamine that induces an antidepressant effect increases BDNF protein levels in the hippocampus (Garcia et al., 2008).”

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.
