Age-appropriate acute stress, such as cold exposure, provokes the secretion of corticotropin releasing factor (CRF) from the hypothalamus, leading to a robust increase of plasma corticosterone in the immature rat. This activation of the hypothalamic-pituitary-adrenal system is accompanied by a stress-induced increase of steady-state CRF-mRNA expression in the hypothalamic paraventricular nucleus (PVN). In the current study, we analysed changes in CRF-mRNA expression in the PVN and the central nucleus of the amygdala (ACe) in the immature rat in response to a single episode of cold stress and three repeated exposures to this same stressor. CRF-mRNA expression in the PVN increased after a single, but not repeated exposures to cold stress, while repeated acute stress increased the content of the CRF peptide in the anterior hypothalamus. In the ACe, repeated episodes of cold stress resulted in increased expression of CRF-mRNA. These findings indicate a differential regulation of CRF gene expression in the PVN and ACe of the immature rat by single and repeated acute stress.
