Corticotropin-releasing hormone effects on luteinizing hormone and cortisol secretion in intact female rhesus macaques.
It is generally accepted that corticotropin-releasing hormone (CRH) is the central mediator of stress-activated changes in the pituitary-adrenal axis because it results in the release of ACTH and ultimately increases the systemic levels of cortisol. And, because in some situations CRH also inhibits the hypothalamic release of GnRH, it has been presumed that it plays the central role in stress-r...
متن کاملPlacental corticotropin-releasing hormone may be a stimulator of maternal pituitary adrenocorticotropic hormone secretion in humans.
To clarify the physiological role of placental corticotropin-releasing hormone (CRH), we measured plasma CRH, ACTH, and cortisol throughout pregnancy. Cerebrospinal fluid (CSF) CRH levels and ACTH responsiveness to synthetic CRH were also quantified in pregnant and nonpregnant women. Maternal plasma CRH levels, which increased progressively during pregnancy, correlated well with both ACTH and c...
متن کاملRegulation of adrenocorticotropic hormone secretion: lessons from mice deficient in corticotropin-releasing hormone.
words of Hans Selye from the 1940s still ring true today. Selye recognized that physical, emotional, and environmental challenges (stressors) elicit a variety of physiological responses and that our ability to respond and adapt to these stressors is critical to our survival. In the 50 years since these initial observations, we have learned a great deal about the complex system that allows us to...
متن کاملCorticotropin-releasing hormone physiology
Corticotropin-releasing hormone (CRH), also known as corticotropin-releasing factor, is a highly conserved peptide hormone comprising 41 amino acid residues. Its name derives from its role in the anterior pituitary, where it mediates the release of corticotropin (ACTH) leading to the release of adrenocortical steroids. CRH is the major hypothalamic activator of the hypothalamic–pituitary– adren...
متن کاملCorticotropin-releasing hormone receptors.
Corticotropin-releasing hormone (CRH) and related peptides (urocortins, sauvagine, urotensin) play a central role in the co-ordination of autonomic, behavioural, cardiovascular, immune and endocrine responses to stressful stimuli. Their actions are mediated through activation of two types of G-protein-coupled receptors encoded by separate genes. In this review we focus on the diverse structural...
