Fattore di rilascio della corticotropina

Descrizione:

Fattore di rilascio della corticotropina (CRF), noto anche come ormone di rilascio della corticotropina (CRH), è un ormone peptidico coinvolto nella risposta allo stress. Viene prodotto nell'ipotalamo e gioca un ruolo cruciale nell'asse ipotalamo-ipofisi-surrene (HPA) stimolando il rilascio dell'ormone adrenocorticotropo (ACTH) dalla ghiandola pituitaria. Il CRF è composto da 41 aminoacidi e presenta una gamma di attività biologiche, inclusa la modulazione della risposta immunitaria e l'influenza sul comportamento e sull'umore. La sostanza è caratterizzata dalla sua capacità di legarsi a recettori specifici, vale a dire i recettori CRF 1 e 2, che sono distribuiti in tutto il cervello e nei tessuti periferici. Il CRF è anche implicato in vari processi fisiologici, inclusa la regolazione dei ritmi circadiani e la risposta agli stressori. La sua disregolazione è associata a diversi disturbi psichiatrici e fisiologici, rendendolo un obiettivo per la ricerca in condizioni legate allo stress. Il numero CAS 9015-71-8 identifica in modo univoco questo peptide nelle banche dati chimiche, facilitando il suo studio e la sua applicazione nella ricerca biomedica.

CRF (Ovine)

CAS: 9015-71-8

Corticotropin Releasing Factor (CRF) is a peptide hormone involved in the regulation of the neuroendocrine system, the hypothalamic-pituitary-adrenal (HPA) axis. The hypothalamus releases CRF during stress and in turn CRF stimulates the production of stress hormones such as glucocorticoids and adrenocorticotropin (ACTH). A negative feedback loop is created as glucocorticoids then prevents further endocrine activity exhibited by the pituitary gland and hypothalamus. Interestingly in patients with depression, it has been found that the hypothalamic-pituitary adrenal axis is over stimulated thus increased production of CRF occurs resulting in depression symptoms. Furthermore studies have shown the expression of CRF receptors in glial cells and T-cells and elevated levels of CRF and glucocorticoids prevent T-cell proliferation. During stress cytokines can also stimulate the secretion of CRF. However CRF can also regulate these cytokines. CRF has the potential to be used in the research into depression treatments. 
This product is available as a 0.1mg vial.

CRF (Ovine)

CAS: 9015-71-8

This product is an ovine, Corticotropin Release Factor (CRF) and is available as a 0.5mg vial. CRF is a peptide hormone and a key regulator of the hypothalamic-pituitary adrenal (HPA) axis. In response to stress the hypothalams releases CRF which stimulates the production of glucocorticoids and adrenocorticotropin, which are stress hormones. Glucocorticoids are then involved in a negative feedback loop, in that they prevent the pituitary gland and hypothalamus from exhibiting any further endocrine activity. Studies have shown that symptoms of depression can be caused by the over production of CRF due to the overstimulation of the hypothalamic-pituitary adrenal axis. Interestingly CRF receptors are expressed in both glial cells and T cells. Elevated levels of CRF and glucocorticoids prevent T-cell proliferation. During stress cytokines can also stimulate the secretion of CRF. However CRF can also regulate these cytokines. CRF has the potential to be used in the research into depression treatments.
