Structural and functional evolution of vertebrate neuroendocrine stress systems

Abstract

The vertebrate hypothalamus-pituitary-adrenal (HPA; or interrenal) axis plays pivotal roles in animal development and in physiological and behavioral adaptation to environmental change. The HPA, or stress axis, is organized in a hierarchical manner, with feedback operating at several points along the axis. Recent findings suggest that the proteins, gene structures, and signaling pathways of the HPA axis were present in the earliest vertebrates and have been maintained by natural selection owing to their critical adaptive roles. In all vertebrates studied, the HPA axis is activated in response to stressors and is controlled centrally by peptides of the corticotropin-releasing factor (CRF) family of which four paralogous members have been identified. Signaling by CRF-like peptides is mediated by at least two distinct G protein-coupled receptors and modulated by a secreted binding protein. These neuropeptides function as hypophysiotropins and as neurotransmitters/neuromodulators, influencing stress-related behaviors, such as anxiety and fear. In addition to modulating HPA activity and behavioral stress responses, CRF-like peptides are implicated in timing key life history transitions, such as metamorphosis in amphibians and birth in mammals. CRF-like peptides and signaling components are also expressed outside of the central nervous system where they have diverse physiological functions. Glucocorticoids are the downstream effectors of the HPA axis, playing essential roles in development, energy balance and behavior, and feedback actions on the activity of the HPA axis.

  • Fear, anxiety, and aggression are stress responses, mediated across vertebrates by the hypothalamic-pituitary-adrenal (HPA) axis.

    “Fear, anxiety, and aggression are stress responses, mediated across vertebrates by the hypothalamic-pituitary-adrenal (HPA) axis (Denver, 2009;Haller, 2014), the hypofunction of which has been proposed as a key mechanism in the development of tame behaviors in domesticates (Trut et al., 2009;Wilkins et al., 2014).”

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.
