Background

Corticotropin-releasing factor (CRF), also known as corticotropin-releasing hormone (CRH), is a 41-amino acid neuropeptide belonging to the corticotropin-releasing factor family. In mammals, CRF is predominantly expressed in the paraventricular nucleus of the hypothalamus, the central nucleus of the amygdala, the bed nucleus of stria terminalis (BNST), and some other brain regions (1-4).
CRF is a critical mediator of the endocrine stress response. Following stress exposure, CRF activates the hypothalamic-pituitary-adrenal (HPA) axis by stimulating the release of adrenocorticotropic hormone (ACTH) from the anterior pituitary, leading to glucocorticoid secretion from the adrenal cortex (5). Beyond its role in stress response, CRF is involved in different aspects of social behavior (4).
CRF dysregulation is implicated in stress-related mood disorders such as anxiety, depression (6, 7), and Alcohol Use Disorder (AUD) (2).
