Morning plasma concentrations of beta-endorphin immunoreactivity were significantly higher in a group of depressed patients meeting the Research Diagnostic Criteria for Major Depressive disorder or Schizo-affective disorder, depressed, than in age- and sex-matched groups of normal controls and psychiatric patients without affective disorders. Furthermore, physostigmine-stimulated release of beta-endorphin immunoreactivity was also significantly greater in the depressed patients. These results provide the first evidence for elevated plasma concentrations of beta-endorphin in depression and also represent further evidence for cholinergic supersensitivity in depression. These results suggest that elevated plasma concentrations of beta-endorphin and cholinergically stimulated hypothalamic-pituitary beta-endorphin release, might potentially represent biological state or trait markers for depression.

Depressive disorders are a leading cause of morbidity and mortality worldwide. Current antidepressant drugs targeting monoamine neurotransmitter systems have a delayed onset of action, and fewer than 50% of the patients attain complete remission after therapy with a single antidepressant. A large body of preclinical and clinical evidence points to a key role of the corticotropin-releasing hormone (CRH) receptor 1 subtype (CRHR1) in mediating CRH-elicited effects in anxiety, depressive disorders and stress-associated pathologies. Genetic modification of CRHR1 function in mice by the use of conventional and conditional knockout strategies enables further analysis of specific elements in the CRH circuitry. The recent characterisation of several selective small-molecule CRHR1 antagonists offers new possibilities for the treatment of anxiety and depression.
