Abstract

Depression is frequently associated with cognitive disturbances. Vortioxetine is a multimodal acting antidepressant that functions as a 5-HT3 and 5-HT7 and 5-HT1D receptor antagonist, 5-HT1B receptor partial agonist, 5-HT1A receptor agonist and inhibitor of the 5-HT transporter. Given its pharmacological profile, the present study was undertaken to determine whether vortioxetine could modulate several preclinical parameters known to be involved in cognitive processing. In the dorsal hippocampus of anaesthetized rats, the high-frequency stimulation of the Schaffer collaterals provoked a stable long-term potentiation (LTP) of ~25%. Interestingly, vortioxetine (10mg/kg, i.p.) counteracted the suppressant effect of elevated platform stress on hippocampal LTP induction. In the novel object recognition test, vortioxetine (10mg/kg, i.p.) increased the time spent exploring the novel object during the retention test and this pro-cognitive effect was prevented by the partial 5-HT3 receptor agonist SR57227 (1mg/kg, i.p.). Finally, compared to fluoxetine, sustained administration of vortioxetine (5mg/kg/day, s.c.) induced a rapid increase of cell proliferation in the hippocampal dentate gyrus. In summary, vortioxetine prevented the effect of stress on hippocampal LTP, increased rapidly hippocampal cell proliferation and enhanced short-term episodic memory, via, at least in part, its 5-HT3 receptor antagonism. Taken together, these preclinical data suggest that the antidepressant vortioxetine may have a beneficial effect on human cognitive processes.

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.
