Abstract

This study extends earlier work on the role of vascular endothelial growth factor (VEGF) in the actions of antidepressant treatment in two key areas. First, by determining the requirement for VEGF in the actions of a 5-HT selective reuptake inhibitor (SSRI), fluoxetine in behavioral models of depression/antidepressant response; and second, by examining the role of the 5-HT1A receptor subtype in the regulation of VEGF, and the cellular localization of antidepressant regulation of VEGF expression. The results show that pharmacological inhibition of VEGF receptor signaling blocks the behavioral actions of fluoxetine in rats subjected to chronic unpredictable stress. Infusions of SU5416 or SU1498, two structurally dissimilar inhibitors of VEGF-Flk-1 receptor signaling, block the antidepressant effects of fluoxetine on sucrose preference, immobility in the forced swim test, and latency to feed in the novelty suppressed feeding paradigm. We also show that activation of 5-HT1A receptors is sufficient to induce VEGF expression and that a 5-HT1A antagonist blocks both the increase in VEGF and behavioral effects induced by fluoxetine. Finally, double labeling studies show that chronic fluoxetine administration increases VEGF expression in both neurons and endothelial cells in the hippocampus. Taken together these studies show that VEGF is necessary for the behavioral effects of the SSRI fluoxetine, as well as norepinephrine selective reuptake inhibitor, and that these effects may be mediated by 5-HT1A receptors located on neurons and endothelial cells.

  • VEGF seems to be required for the behavioral action of various antidepressant drugs in rodent models of depression.

    “In a similar manner, VEGF also seems to be required for the behavioral action of various antidepressant drugs in rodent models of depression (Greene et al. 2009; Sun et al. 2012; Warner-Schmidt and Duman 2007; Warner-Schmidt and Duman 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.
