The cannabinoid receptor CB1 inverse agonist AM251 potentiates the anxiogenic activity of urocortin I in the basolateral amygdala

Abstract

The basolateral amygdala is reported to play an important role in the neural bases of emotional processing. Previous studies have shown that injections of urocortin I (UcnI) into the basolateral amygdala (BLA) elicit anxiety-like behaviors in animal models. The present study examined the anxiogenic effects of UcnI administered directly into the BLA of male Sprague-Dawley rats. UcnI was administered at doses of 0.1-10.0 pmol and rats were then placed in an elevated plus maze for 10 min. UcnI reliably decreased the percent time spent in the open arms of the elevated plus maze (EPM) as well as open arm entries. This effect was observed across all doses tested, indicating the induction of anxiety-like behavior. In separate groups of rats, the CB(1) inverse agonist AM251 was administered systemically (0.03-3.0 mg/kg IP) or directly into the BLA (0.25-25.0 pmol) and EPM performance assessed. Both routes of AM251 administration produced a reduction in open arm entries and in time spent in the open arms. Moreover, when rats were pretreated with AM251 either systemically or directly into the BLA, the anxiogenic effect of UcnI was potentiated. That is, co-administration of AM251 and UcnI produced a greater suppression of percent time spent in the open arms and open arm entries as compared to UcnI alone. Based on these findings, we propose that urocortin and endocannabinoid signaling are part of an integrated neural axis modulating anxiety states within the basolateral amygdala. This article is part of a Special Issue entitled 'Anxiety and Depression'.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • CB1R antagonism increases BLA excitability, activates the HPA axis, and increases anxiety-like behavior.

    “First, presumably by removing AEA-mediated tonic inhibitory activity, CB1R antagonism increases BLA excitability [61–63], activates the hypothalamic–pituitary–adrenal (HPA) axis and increases anxiety-like behavior [58,64,65].”

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.
