Corticotropin-releasing hormone

Neuroendocrinology 1 July ; 94 1 : 12— Corticotropin-releasing hormone CRH plays a key role in corticotropin-releasing hormone the basal and stress-activated hypothalamic-pituitary-adrenal axis HPA.

Recent findings suggest that an interaction between the nervous system and immune system might be behind the pathophysiology of various neurological and psychiatric disorders, including depression. Neuropeptides have been shown to play a major role in mediating response to stress and inducing immune activation or suppression. CRF is a stress-related neuropeptide whose dysregulation has been associated with depression. In this review, we summarized the role of CRF in the neuroimmune mechanisms of depression, and the potential therapeutic effects of Chinese herbal medicines CHM as well as other agents. Studying the network of CRF and immune responses will help to enhance our understanding of the pathogenesis of depression. Additionally, targeting this important network may aid in developing novel treatments for this debilitating psychiatric disorder. Depression, also termed as clinical depression or major depressive disorder MDD , is a common but serious mental disorder affecting the quality of human life.

Furthermore, the authors propose that overactivation of this CRH system can play an important aetiological role in the development of acne vulgaris through stimulation of local inflammatory reactions. This conclusion is in accordance with the published information that CRH and related URCs are widely produced by human skin in cell type- and anatomical region-specific manners reviewed. In the context of data presented by Ganceviciene et al. Taking into consideration the abundance of data showing proinflammatory actions of CRH in the skin reviewed , 14 , 15 , 36 one is facing a dilemma: why can the system designed to protect and stabilize play a destructive role by being involved in the aetiology of inflammatory skin disorders? The feedback inhibition of CRH production by F or B is well documented in a number of experimental models. The central role of the CRHR-1 in the above model implies usage of selective receptor antagonists 49 , 50 or alternatively spliced soluble isoforms 15 as adjuvants in the therapy of inflammatory skin disorders. As a library, NLM provides access to scientific literature. Br J Dermatol. Author manuscript; available in PMC Feb 1.

The neuropeptide corticotropin-releasing hormone CRH, also called CRF and corticoliberin plays a key role in the integration of neuroendocrine, autonomic and behavioral responses to stress. The activation of the hypothalamic-pituitary-adrenal axis HPA axis by neurons of the paraventricular hypothalamic nucleus PVN , the primary site of synthesis CRH, triggers stress reactions. In addition to the hypothalamus, CRH is widespread in extrahypothalamic brain structures, where it functions as a neuromodulator for coordination and interaction between the humoral and behavioral aspects of a stress response.

Markella Nezi , M. In this process cellular leukocytes and lymphocytes T, B, NK and extra-cellular elements participate in a complex co-operative network. The balance between Th1 and Th2 is important for the immune system homeostasis.

In terms of behavior, long-term CRHR1 activation as a consequence of chronic stress is associated with impaired potentiation response in the hippocampus. Different brain regions are involved in the stress response system, such as amygdala, hippocampus and the prefrontal cortex PFC Bao and Swaab, Corticotropin-releasing factor receptors 1 and 2 in anxiety and depression. These include behavioral adaptation, and increased survival, as well as an increased risk of developing mental disorders associated with stress. Duman, R. Differential expression of receptors and their ligands in the brain reflect the different actions that CRH has at the CNS level. The effect of lateral septum corticotropin-releasing factor receptor 2 activation on anxiety is modulated by stress. Kinlein, S.

Allergy Clin. Involvement of corticotropin-releasing factor and receptors in immune cells in irritable bowel syndrome. Additionally, targeting this important network may aid in developing novel treatments for this debilitating psychiatric disorder. Behavioral effects of peripheral corticotropin-releasing factor during maternal separation may be mediated by proinflammatory activity. Last reviewed: May Prev. It is believed that the influence of CRH on norepinephrine release, mainly in the LC, underlies the emotional basis of the stress response Valentino, Van Bockstaele, Psychiatry 9, — Complex regulatory interactions control CRH gene expression. Increased corticotrophin-releasing hormone levels within the joints, skin or gut can therefore make these inflammatory conditions worse or even play a role in their development. View large Download slide. These findings suggest that antidepressants, including CHM can restore HPA axis hyperactivity by decreasing CRF levels, and such effect may be due to direct regulation of CRF levels, or indirect regulation of neuroimmune mechanisms. Thyroid hormones T 3 T 4 Calcitonin Thyroid axis.
