Abstract

In rodents, a circadian signal from the suprachiasmatic nucleus (SCN) is essential for the pro‐oestrous surge of gonadotrophin‐releasing hormone (GnRH), which, in turn, induces luteinising hormone (LH) surge and ovulation. We hypothesised that kisspeptin (KP) neurones in the anteroventral periventricular and periventricular preoptic nuclei (AVPV/PeN) form part of the communication pathway between the SCN and GnRH neurones. In anterograde track tracing studies, we first identified vasopressin (VP)‐containing axons of SCN origin in apposition to KP‐immunoreactive (IR) neurones. Studies to quantify this input relied on the observation that VP‐synthesising neurones in the SCN differ from other VP systems in their lack of galanin expression. In ovariectomised mice, 30.79 ± 1.63% of KP‐IR perikarya and proximal dendrites within the AVPV/PeN received galanin‐negative VP‐IR varicosities. Oestrogen‐treatment significantly increased the number of KP‐IR neurones, with their percentage apposed by galanin‐negative VP‐IR varicosities (46.95 ± 1.88%) and the number of VP‐IR appositions on individual KP‐IR neurones. At the ultrastructural level, the VP‐IR terminals formed symmetric synapses with KP‐IR neurones, which was in accordance with the morphology of inhibitory synapses established by SCN neurones. By contrast to VP, vasoactive intestinal polypeptide (VIP), which is synthesised by a distinct subset of SCN neurones, occurred only rarely in axons apposed to KP‐IR neurones. Altogether, our results are consistent with the hypothesis that KP neurones located in the mouse AVPV/PeN receive circadian information from the SCN via a vasopressinergic monosynaptic pathway, which is enhanced by oestrogen.

  • E2 restores AVP-induced activation of AVPV/PeN kisspeptin neurons in ovariectomized female mice.

    “However, E2 restores AVP-induced activation of kisspeptin neurons in the AVPV/PeN in ovariectomized (OVX) female mice49,50”

    From Emerging insights into hypothalamic‐pituitary‐gonadal axis regulation and interaction with stress signalling (2018) · cites this paper as [50]

    The Results report that E2 treatment increased vasopressin-containing contacts onto kisspeptin neurons in the RP3V of ovariectomized mice. The Discussion interprets this as enhanced vasopressinergic input, but the paper does not show that E2 restores AVP-induced activation of those neurons. (LLM, conf=0.85)

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.
