Antagonism of CRF2 receptors produces anxiolytic behavior in animal models of anxiety

Abstract

Two pharmacologically distinct CRF receptors are distributed in different brain regions and peripheral tissues. Studies suggest that CRF(1) receptors play an important role in mediating the anxiety provoking effects of CRF. In contrast, far less functional information is available on CRF(2) receptors. Therefore, we conducted dose response studies using antisauvagine-30 (anti-SVG-30, 0-20 microg, 20-min pretreatment, i.c.v.), a potent CRF(2) peptide antagonist, and tested rats in three models of anxiety - the conditioned freezing, the elevated plus maze, and the defensive-withdrawal test. Anti-SVG-30 produced a significant dose-dependent reduction in conditioned freezing. In the elevated plus maze test, administration of anti-SVG-30 effectively increased the number of entries and time spent in the open arms. In the defensive-withdrawal test, anti-SVG-30 treatment facilitated exploratory activity in a large illuminated open field. Thus, in all three animal models, administration of anti-SVG-30 was consistent in producing an anxiolytic-like behavioral effect. In addition, a dose of anti-SVG-30 (10 microg) that produced anxiolytic-like behavior had no significant effects on locomotor activity measured in an automated activity box. This latter finding suggests that antagonism of CRF(2) receptors is not associated with a non-specific increase in behavioral movements. These results provide evidence that, in addition to CRF(1) receptors, CRF(2) receptors may play an important role in the mediation of anxiety behavior.

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

  • CRF-R1 activation mediates many stress effects in rats; CRF-R2 activation can be the same, opposing, or ineffective depending on assay and brain region.

    “CRF-R1 activation mediates many of these stress effects in rats, while CRF-R2 activation is alternately the same as CRF-R1, opposing CRF-R1, or ineffective in modulating stress, depending on the assay and the brain region (Ho et al 2001; Takahashi et al 2001; Valdez et al 2004; Zhao et al 2007; for a review see Heinrichs and Koob, 2004).”

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.
