CRF (human, rat) is an endogenous peptide agonist of the corticotropin-releasing factor (CRF) receptor, with Ki values of 3.3, 42, and 47nM for hCRF1, rCRF2A, and mCRF2B, respectively[1]. CRF (human, rat) is a hypothalamic peptide composed of 41 amino acids that is widely expressed in neurons throughout the mammalian brain and some peripheral tissues (such as the pancreas, stomach, and small intestine)[2]. CRF can stimulate the synthesis and secretion of adrenocorticotropic hormone (ACTH) in the anterior pituitary[3]. CRF can increase the excitability of type II dlBNST neurons by activating the AC-cAMP-PKA pathway, thereby causing pain-induced aversion reactions[4]. The acute central anorectic and hypermetabolic effects of CRF are affected by age and gender[5].
