Abstract

The aim of this study was to label selectively and to map central vasopressin (AVP) and oxytocin (OT) binding sites in the common marmoset. [(125)I]VPA, a compound selective in rodents and human for the AVP V(1a) receptor, yielded the same labeling pattern as [(3)H]AVP, thus suggesting that most AVP receptors present in the marmoset brain are of the V(1a) subtype. Numerous areas exhibited AVP binding sites, among which the olfactory bulb, the accumbens nucleus, the bed nucleus of the stria terminalis, the hypothalamic suprachiasmatic, arcuate and ventromedial nuclei, the medial amygdaloid nucleus, the nucleus of the solitary tract and the cerebral cortex. Binding sites for [(125)I]OTA, a selective OT receptor antagonist in rat and human, were markedly less abundant than [(125)I]VPA ones, and, to a few exceptions, expressed in different areas. Neither AVP, nor OT binding sites were detected in the hypothalamic paraventricular (PVN) and supraoptic (SON) nuclei identified by neurophysin immunoreactivity. Marked species-related differences were observed in the distribution of both AVP and OT binding sites. Altogether, our data provide a morphological basis to investigate the function of central AVP and OT in the marmoset.

Claims the paper makes

We couldn’t retrieve this paper’s full text, 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?

  • The common marmoset has dense oxytocin receptor binding in the nucleus accumbens.

    “However, the dense OXTR binding seen in the NAcc of the common marmoset (30) makes marmosets a particularly appropriate choice for exploring the role of OT in social reward, which would complement recent discoveries in mice (25).”
  • 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 highly social and selectively breeding marmoset has dense oxytocin receptor binding in the nucleus accumbens, similar to the prairie vole.

    “For example, the highly social and selectively breeding marmoset has dense OXTR in the NAcc (Fig. 3a) similar to that of the prairie vole (30,85).”
  • Other monogamous species, including common marmosets and the California mouse, also have similarly high levels of V1aR in the ventral forebrain region compared to related non-monogamous species.

    “Interestingly, other monogamous species, including common marmosets and the California mouse (Peromyscus californicus) also have similarly high levels of V1aR in this ventral forebrain region compared to related non-monogamous species [17, 22].”
  • Females in non-monogamous vole species as well as mice display very low or no OTR binding in the NAcc.

    “Females in non-monogamous vole species as well as mice, display very low or no OTR binding in the NAcc, while the monogamous common marmoset (Callithrix jacchus) has high densities of OTR in this region much like the prairie vole [17].”

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.
