Factor liberador de corticotropina

Descripción:

Factor liberador de corticotropina (CRF), también conocido como hormona liberadora de corticotropina (CRH), es una hormona peptídica involucrada en la respuesta al estrés. Se produce en el hipotálamo y juega un papel crucial en el eje hipotálamo-hipófiso-adrenal (HPA) al estimular la liberación de hormona adrenocorticotrópica (ACTH) de la glándula pituitaria. El CRF está compuesto por 41 aminoácidos y exhibe una variedad de actividades biológicas, incluyendo la modulación de la respuesta inmune y la influencia en el comportamiento y el estado de ánimo. La sustancia se caracteriza por su capacidad para unirse a receptores específicos, a saber, los receptores de CRF 1 y 2, que están distribuidos por todo el cerebro y los tejidos periféricos. El CRF también está implicado en varios procesos fisiológicos, incluyendo la regulación de los ritmos circadianos y la respuesta a los estresores. Su desregulación se asocia con varios trastornos psiquiátricos y fisiológicos, lo que lo convierte en un objetivo para la investigación en condiciones relacionadas con el estrés. El número CAS 9015-71-8 identifica de manera única este péptido en bases de datos químicas, facilitando su estudio y aplicación en la investigación biomédica.

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.
