Abstract

The neuropeptides oxytocin (OXT) and arginine vasopressin (AVP) contribute to the regulation of diverse cognitive and physiological functions including nociception. Indeed, OXT has been reported to be analgesic when administered directly into the brain, the spinal cord, or systemically. Here, we characterized the phenotype of oxytocin receptor (OTR) and vasopressin-1A receptor (V1AR) null mutant mice in a battery of pain assays. Surprisingly, OTR knock-out mice displayed a pain phenotype identical to their wild-type littermates. Moreover, systemic administration of OXT dose-dependently produced analgesia in both wild-type and OTR knock-out mice in three different assays, the radiant-heat paw withdrawal test, the von Frey test of mechanical sensitivity, and the formalin test of inflammatory nociception. In contrast, OXT-induced analgesia was completely absent in V1AR knock-out mice. In wild-type mice, OXT-induced analgesia could be fully prevented by pretreatment with a V1AR but not an OTR antagonist. Receptor binding studies demonstrated that the distribution of OXT and AVP binding sites in mouse lumbar spinal cord resembles the pattern observed in rat. AVP binding sites diffusely label the lumbar spinal cord, whereas OXT binding sites cluster in the substantia gelatinosa of the dorsal horn. In contrast, quantitative real-time reverse transcription (RT)-PCR revealed that V1AR but not OTR mRNA is abundantly expressed in mouse dorsal root ganglia, where it localizes to small- and medium-diameter cells as shown by single-cell RT-PCR. Hence, V1ARs expressed in dorsal root ganglia might represent a previously unrecognized target for the analgesic action of OXT and AVP.

  • It is less likely that AVP and OXT may have acted via each other's receptors.

    “Additionally, the neuropeptide- and receptor antagonist-specific effects on social play suggests that it is less likely that AVP and OXT may have acted via each other's receptors (Chini and Manning, 2007; Schorscher-Petcu et al., 2010).”

    From Sex-specific modulation of juvenile social play behavior by vasopressin and oxytocin depends on social context (2014) · cites this paper as Schorscher-Petcu et al., 2010

    The Introduction states that both OXT and AVP can activate both receptors. More decisively, the Results (Oxytocin and vasopressin 1a receptor antagonists) report that a V1AR antagonist prevented OXT-induced analgesia, supporting OXT action through AVP’s receptor rather than making cross-receptor action unlikely. The paper studies analgesia, not social play. (LLM, conf=0.83)

    Checked by a reasoning model — may be wrong.

  • OXT-induced analgesia in mice is mediated by vasopressin-1A receptors.

    “Future studies are needed to elucidate the exact neurochemical cascade underlying the observed OXT effect on approach behavior since OXT-induced analgesia in mice, for example, is mediated by vasopressin-1A receptors (Schorscher-Petcu et al., 2010).”

  • Some actions of oxytocin are mediated via vasopressin receptors and vice versa.

    “Some actions of oxytocin are mediated via vasopressin receptors and vice versa”

    From Oxytocin, Neural Plasticity, and Social Behavior (2021) · cites this paper as Schorscher-Petcu et al. 2010

  • Several previous studies suggested that the effects of oxytocin and vasopressin result from activation of the opposite receptor.

    “This concept is not new; several previous studies suggested that the effects of OT and AVP are a result of the activation of the ‘opposite’ receptor (4,80,86-89).”
  • Peripheral administration of OT or AVP induces analgesia in OTR but not in V1aR knock-out male and female mice.

    “Peripheral administration of OT or AVP induces analgesia in OTR but not in V1aR knock-out male and female mice [40].”

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.
