HPA axis activity and cytokines are intrinsically intertwined : inflammatory cytokines stimulate adrenocorticotropic hormone ( ACTH ) and cortisol secretion, while, in turn, glucocorticoids suppress the synthesis of proinflammatory cytokines.
42.
5-HT 1A receptor activation induces the secretion of various hormones including cortisol, corticosterone, adrenocorticotropic hormone ( ACTH ), oxytocin, prolactin, growth hormone, and ?-endorphin.
43.
Adrenocorticotropic hormone ( ACTH ) and the sympathetic nervous system stimulate the synthesis of adrenaline precursors by enhancing the activity of tyrosine hydroxylase and dopamine ?-hydroxylase, two key enzymes involved in catecholamine synthesis.
44.
Glucocorticoids act to inhibit feedback of both the hypothalamus, decreasing corticotropin-releasing hormone [ CRH ], and corticotrophs in the anterior pituitary gland, decreasing the amount of adrenocorticotropic hormone [ ACTH ].
45.
"' Chromatophobe "'is a general term used in Endocrinology to describe the cell stain type of the anterior pituitary hormone : the corticotroph cells which produce adrenocorticotropic hormone ( ACTH ).
46.
William H . Frey II, a biochemist at the University of Minnesota, proposed that people feel " better " after crying due to the elimination of hormones associated with stress, specifically adrenocorticotropic hormone.
47.
The patient is given an injection of ACTH ( adrenocorticotropic hormone ), the pituitary hormone that tells the adrenals to release corticosteroids, and the resulting amount of cortisol is measured in the blood and urine.
48.
Other tests may be performed to distinguish between various causes of hypoadrenalism, including renin and adrenocorticotropic hormone levels, as well as medical imaging-usually in the form of ultrasound, computed tomography or magnetic resonance imaging.
49.
Trying to identify a mechanism for the " immunology of touch, " some investigators point to modulations of arousal and associated pituitary-adrenal system, which, in turn, leads to increased plasma cortisol and adrenocorticotropic hormone.
50.
The paraventricular nucleus transports CRH to the anterior pituitary, stimulating adrenocorticotropic hormone ( ACTH ) release via CRH type 1 receptors, thereby activating the hypothalamic-pituitary-adrenal axis ( HPA ) and, thus, glucocorticoid release.
