Localization of Vasopressin (V1a) Receptor Binding and mRNA in the Rhesus Monkey Brain

Young, Toloczko, Insel·1999·Journal of Neuroendocrinology

Abstract

Centrally released arginine vasopressin (AVP) has been associated with various behavioural and cognitive effects, such as scent marking, aggression, and memory, which are believed to be mediated by the V 1a subtype of the vasopressin receptor. Although the distribution of V 1a receptors is conserved in a few brain regions, the pattern of expression of this receptor is, in general, highly species‐specific. We have used receptor autoradiography with the linear V 1a receptor ligand (125 I‐Phenylacetyl‐D‐Tyr(Me)‐Phe‐Gln‐Asn‐Arg‐Pro‐Arg‐Tyr‐NH 2) to characterize the pattern of receptor binding in the rhesus monkey brain. Brain sites of V 1a receptor synthesis were defined using in‐situ hybridization. The regions of highest V 1a receptor density included the prefrontal, cingulate, pyriform, and entorhinal cortex, as well as the presubiculum and mamillary bodies. In addition, V 1a receptor binding and mRNA were detected in several regions reported to have V 1a receptor in most rodents, including the amygdala, bed nucleus of the stria terminalis, lateral septum, hypothalamus and the brainstem. The distribution is consistent with a role for vasopressin in higher cognitive functions, especially memory, in primates.

  • Before the pharmacological limitations were understood, these radioligands were used for receptor autoradiography in the common marmoset, rhesus macaque, and human.

    “Nevertheless, before these pharmacological limitations were fully understood, these radioligands (as well as the older tritiated versions of the endogenous neuropeptides themselves) were used for receptor autoradiography in three primate species: in the common marmoset for OXTR and AVPR1a (29,30), in the rhesus macaque for AVPR1a (31), and in human for OXTR and AVPR1a (32,33).”
  • The rhesus macaque brain exhibits extremely sparse oxytocin receptor expression relative to vasopressin receptor 1a, with the densest oxytocin receptor binding in the nucleus basalis of Meynert and superficial grey layer of the superior colliculus.

    “The rhesus macaque brain in general exhibits extremely sparse OXTR expression relative to AVPR1a (27,31), with the most dense OXTR binding seen in the NBM and superficial grey layer of the SC (Fig. 2c,f).”
  • V1aR is widely distributed throughout the brain of Macaca, with notable expression in the social-decision making network and in regions within social/cognitive circuits, including CeA, PFC, CC, and IC.

    “Similar to Callithrix and Callicebus, V1aR is widely distributed throughout the brain of Macaca, with notable expression in the social-decision making network as well in regions conventionally identified within social/cognitive circuits, including the CeA, PFC, CC, and IC (confirmed by in situ hybridization; Young et al., 1999).”
  • Male and female Macaca and Homo display similar density and distribution of V1aR.

    “The limited information on sex differences in V1aR shows that male and female Macaca (Young et al., 1999) and Homo (Loup et al., 1991) display similar density and distribution of V1aR.”

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.
