title: Decreased 5-HT-mediated prolactin release in major depression.
abstract: The prolactin response to intravenous clomipramine, a 5-HT uptake inhibitor, was significantly attenuated in 12 patients with major depression. In contrast, in a further 12 depressed patients, the PRL responses to thyrotropin-releasing hormone, which acts directly on the pituitary to release PRL, were not reduced. These findings suggest that the reduction in 5-HT-mediated PRL release seen in depressed patients is due to an impairment of brain 5-HT function rather than a pituitary abnormality.
