The hypothalamo-pituitary-adrenocortical system.
Control of the secretion of ACTH appears to involve several mechanisms. It is dependent upon the release, from neurones in the hypothalamus, of corticotrophin releasing factor, which is probably a complex including CRF-41 and vasopressin. The secretion of the complex is influenced by various central inhibitory and excitatory nervous pathways. The releasing factor is conveyed by the hypophyseal ...
متن کاملLimbic system mechanisms of stress regulation: hypothalamo-pituitary-adrenocortical axis.
Limbic dysfunction and hypothalamo-pituitary-adrenocortical (HPA) axis dysregulation are key features of affective disorders. The following review summarizes our current understanding of the relationship between limbic structures and control of ACTH and glucocorticoid release, focusing on the hippocampus, medial prefrontal cortex and amygdala. In general, the hippocampus and anterior cingulate/...
متن کاملNeurocircuitry of stress integration: anatomical pathways regulating the hypothalamo-pituitary-adrenocortical axis of the rat.
The hypothalamo-pituitary-adrenocortical (HPA) axis is recruited by the organism in response to real or perceived threats to homeostasis ("stress"). Regulation of this neuroendocrine system is accomplished by modulation of secretory tone in hypophysiotrophic neurons of the medial parvocellular paraventricular nucleus. Excitation of these neurons is mediated by several sources: direct (and perha...
متن کاملDifferential responses of the hypothalamo-pituitary-adrenocortical axis to acute restraint stress in Hatano high- and low-avoidance rats.
The high- and low-avoidance animal (HAA and LAA respectively) strains of Hatano rats were originally selected and bred from Sprague-Dawley rats for their performance in the shuttle-box task. The present study focused on the activity of the hypothalamo-pituitary-adrenocortical (HPA) axis of HAA and LAA rats in response to restraint stress. The restraint stress induced an elevation in plasma conc...
متن کاملA pilot study on hypothalamo-pituitary-adrenocortical axis in primary hyperparathyroidism.
BACKGROUND & OBJECTIVE Parathormone (PTH) and calcium, both have been shown to stimulate adrenal steroidogenesis in animal models and in vitro experiments. This is attributed to structural similarity between 15-25 amino acid region of the parathyroid hormone (PTH) and 1-11 amino acid region of adrenocorticotropin (ACTH). However, there are no in vivo human data regarding the effect of PTHcalciu...
