<p>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.

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.</p>
