Diversity of oxytocin neurones: Beyond magno‐ and parvocellular cell types?

Althammer, F., Grinevich, V.·2018·Journal of Neuroendocrinology

Abstract

The hypothalamic neuropeptide oxytocin ( OT ), which is evolutionarily conserved among different species throughout the animal kingdom, is a key modulator of a variety of socio‐emotional behaviours such as fear, trust and empathy. OT cells in the mammalian hypothalamus have been traditionally divided into two distinct types: agnocellular (magn OT ) and parvocellular (parv OT ) or preautonomic neurones. This distinction is based on OT cell sizes and shapes, projections, electrophysiological activity and functions. Indeed, although neuroendocrine magn OT neurones are known to primarily project their axons to the posterior pituitary and to a number of forebrain regions, non‐neuroendocrine parv OT neurones have been seen as the main source of OT innervation of the brainstem and spinal cord to control autonomic functions and pain perception. However, very recent findings have demonstrated distinct genetic profiles in OT neurones, allowing the discrimination of at least four types of cells expressing OT . Furthermore, unexpected axonal projections of parv OT neurones to the forebrain and magn OT neurones to the midbrain have been newly reported. In this review, we focus on the detailed analysis of methods of distinction between OT cell types, in‐ and output sites, and morphology, as well as on the direct connectivity between OT neurones and its physiological significance. Finally, we propose a hypothesis suggesting that the central OT system is composed of more than just two OT cell types, which needs to be confirmed by the application of available genetic and anatomical techniques.

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?

  • Suckling triggers the release of oxytocin.

    “Suckling triggers the release of oxytocin, but other sensory cues—specifically, infant cries—can increase the levels of oxytocin in new human mothers7”
  • Oxytocin is important for maternal physiology and childcare, including parturition and milk ejection during nursing.

    “Oxytocin is a neuropeptide that is important for maternal physiology and childcare, including parturition and milk ejection during nursing1–6.”
  • Oxytocin is produced mainly in the paraventricular nucleus and supraoptic nucleus of the hypothalamus.

    “oxytocin, a nine-amino-acid peptide that is produced mainly in the paraventricular nucleus (PVN) and supraoptic nucleus of the hypothalamus1–4”
  • Parvocellular neurons can directly activate magnocellular neurons and have been proposed to operate as master cells that control the activity of magnocellular cells and gate oxytocin release.

    “Parvocellular neurons can also directly activate magnocellular neurons and have been proposed to operate as ‘master cells’ that control the activity of magnocellular cells and gate oxytocin release1,13.”

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.
