A delay-differential equation model of the feedback-controlled hypothalamus-pituitary-adrenal axis in humans.

چکیده
The present work develops and analyses a model system of delay-differential equations which describes the core dynamics of the stress-responsive hypothalamus-pituitary-adrenal axis. This neuroendocrine ensemble exhibits prominent pulsatile secretory patterns governed by nonlinear and time-delayed feedforward and feedback signal interchanges. Formulation and subsequent bifurcation analysis of the model provide a qualitative and mathematical frame work for a better understanding of the delayed responsive mechanisms as well as the dynamic variations in different pathological situations.

Objective(s): To investigate the effects of paeoniflorin (PEF) on the hypothalamic-pituitary-adrenal (HPA) axis feedback function of post-traumatic stress disorder (PTSD). cSingle-prolonged stress (SPS) was used to establish a PTSD-like rat model. The contents of plasma corticosterone (CORT), adrenocorticotropin hormone (ACTH) and cortic...

Introduction: The activity of Hypothalamus-Pituitary-Adrenal (HPA) axis is increased following inflammation due to its closed relation with immune system. This axis indicates an increased secretion of ACTH, and corticosterone during acute inflammation while little is known about its activity during chronic inflammation such as rheumatoid arthritis (RA). In this study we measured the products...
متن کاملHypothalamus Pituitary Adrenal axis and stimulatory G proteins signaling role in nociceptive changes induced by forced swim stress
Introduction: Different mechanisms are involved in stress induced analgesia (SIA) and hyperalgesia (SIH). Repeated stress induces development of tolerance to SIA. The role of HPA axis and Gs signaling pathway in these effects are investigated in the current study. Methods: Forced swim stress (5 min/day) in water (20±1 ºC) was employed to adult male Wistar rats (200-250 g). The nociceptive t...
متن کاملThe Role of the Endocannabinoids in Suppression of the Hypothalamic- pituitary-adrenal Axis Activity by Doxepin
Objective(s) The mechanism(s) by which antidepressants regulate the hypothalamic-pituitary-adrenal (HPA) axis remain elusive. The endocannabinoid system (eCBs) which exhibits antidepressant potential, appears to regulate the HPA axis activity. Therefore, we aimed to investigate the role of the eCBs in the action of doxepin including its effect on the HPA axis. Materials and Methods Male Wist...
