title: Muscarinic supersensitivity of anterior pituitary ACTH and B-endorphin release in major depressive illness.
abstract: Subjects with major depressive illness had greater increases in plasma concentrations of ACTH and B-endorphin immunoreactivity in response to central muscarinic stimulation by physostigmine, than did normal control subjects, or psychiatric control subjects without major depressive illness. These findings provide further evidence for muscarinic receptor supersensitivity in depression and may implicate an abnormality of peptide physiology in the pathogenesis of depression.
