Abstract

We reported previously that the neuropeptide oxytocin attenuates stress-induced hypothalamo-pituitary-adrenal (HPA) activity and anxiety behavior. This study sought to identify forebrain target sites through which oxytocin may mediate its anti-stress effects. Ovariectomized, estradiol-treated rats received intracerebroventricular infusions of oxytocin (1 or 10 ng/hr) or vasopressin (10 ng/hr), and the patterns of neuronal activation after restraint stress were determined by semiquantitative mapping of c-fos mRNA expression. Oxytocin administration significantly attenuated the release of ACTH and corticosterone and the increase in corticotropin-releasing factor mRNA expression in the hypothalamic paraventricular nucleus (PVN) in response to 30 min restraint. Restraint also induced the expression of c-fos mRNA in selective regions of the forebrain, including the PVN, paraventricular thalamic nucleus, habenula, medial amygdala, ventrolateral septum (LSV), most subfields of the dorsal and ventral hippocampus, and piriform and endopiriform cortices. In most cases, this level of gene expression was unaffected by concomitant administration of oxytocin. However, in the PVN, LSV, and throughout all subfields of the dorsal hippocampus, restraint evoked no detectable increase in c-fos mRNA in animals treated with either dose of oxytocin. Vasopressin had no effects on either HPA axis responses or neuronal activation in response to restraint, indicating that the effects were highly peptide selective. These data show that central oxytocin attenuates both the stress-induced neuroendocrine and molecular responses of the HPA axis and that the dorsal hippocampus, LSV, and PVN constitute an oxytocin-sensitive forebrain stress circuit.

  • When delivered to the PVN, OT decreases HPA axis gain, as shown by decreased CORT and ACTH levels.

    “Although OT can act at the pituitary to enhance CRH action, when delivered to the PVN, OT decreased HPA axis gain, as shown by decreased CORT and ACTH levels (Neumann, Krömer, Toschi, & Ebner, 2000; Windle et al., 2004; Windle, Shanks, Lightman, & Ingram, 1997).”

    The Results section reports that oxytocin reduced restraint-induced ACTH and corticosterone levels. However, the Methods section specifies delivery into the lateral ventricle, not directly into the PVN; the Discussion describes a PVN site of action as a possibility, not a demonstrated delivery site.

  • Centrally administered oxytocin diminishes stress-induced adrenocorticotropic hormone and corticosterone release, and inhibits corticotropin releasing factor mRNA expression in the hypothalamus during restraint stress in rats.

    “Centrally administered OT also diminishes stress-induced adrenocorticotropic hormone (ACTH) and cor-ticosterone release, and inhibits corticotropin releasing factor (CRF) mRNA expression in the hypothalamus during restraint stress in rats (Windle et al., 2004).”

  • When administered intranasally, oxytocin attenuates the neuroendocrine stress response in rodents and monkeys and alters emotion regulation in humans.

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.
