WebNov 28, 2006 · Corticotropin-releasing hormone (CRH), a neuropeptide encoded by the Crh gene, coordinates the behavioral and physiologic response to stress . The combination of increased anxiety and elevated stress-induced corticosterone release in Mecp2 308/Y mice led us to hypothesize that these animals might also have enhanced Crh expression. WebAbstract. Corticotropin releasing hormone (CRH) is essential for stress adaptation by mediating hypothalamic-pituitary-adrenal (HPA) axis, behavioral and autonomic responses to stress. Activation of CRH neurons depends on neural afferents from the brain stem and limbic system, leading to sequential CRH release and synthesis. drawing a site plan template
