Interactions of the circadian CLOCK system and the HPA-axis
Open accessAbstract
Organisms have developed concurrent behavioral and physiological adaptations to the strong influence of day/night cycles, as well as to unforeseen, random stress stimuli. These circadian and stress-related responses are achieved by two highly conserved and interrelated regulatory networks, the circadian CLOCK and stress systems, which respectively consist of oscillating molecular pacemakers, the Clock/Bmal1 transcription factors, and the hypothalamic-pituitary-adrenal (HPA) axis and its end-effector, the glucocorticoid receptor. These systems communicate with one another at different signaling levels and dysregulation of either system can lead to development of pathologic conditions. In this review, we summarize the mutual physiologic interactions between the circadian CLOCK system and the HPA axis, and discuss their clinical implications.

The ultradian pattern is caused by intrinsic dynamics of the HPA axis itself.
“It is generally believed that the circadian pattern is modulated by exogenous factors such as daylight, temperature, psychological as well as physical stress, but that the ultradian pattern is caused by intrinsic dynamics of the HPA axis itself [13, 19, 32, 36, 54].”
From Patient specific modeling of the HPA axis related to clinical diagnosis of depression (2017) · cites this paper as [36]
The section “The stress HPA axis” describes a negative-feedback loop, and “Regulation of the HPA axis by the circadian CLOCK system” discusses circadian glucocorticoid rhythms. Neither identifies an ultradian pattern or says that intrinsic HPA-axis dynamics cause it; searches for “ultradian” and pulsatile HPA oscillations found no such passage in our copy. (LLM, conf=0.75)

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.
