title: Reduced corticotropin releasing factor binding sites in the frontal cortex of suicide victims.
abstract: Previous studies have provided evidence that corticotropin releasing factor (CRF) is hypersecreted in patients with major depression. This CRF hypersecretion is believed to contribute at least in part to hyperactivity of the hypothalamic-pituitary-adrenal axis in depressed patients. If CRF is chronically hypersecreted in depressed patients, then, due to down-regulation, a reduced number of CRF receptor binding sites should be present in patients with profound depressive disorder. To test this hypothesis, we measured the number and affinity of CRF binding sites in the frontal cortex of 26 suicide victims and 29 controls who died of a variety of causes. There was a marked (23%) reduction in the number of CRF binding sites in the frontal cortex of the suicide victims compared with the controls. These data are consistent with the hypothesis that CRF is hypersecreted in depression.
