The opiate withdrawal syndrome is a severe stressor that powerfully triggers addictive drug intake. However, no treatment yet exists that effectively relieves opiate withdrawal distress and spares stress-coping abilities. The corticotropin-releasing factor (CRF) system mediates the stress response, but its role in opiate withdrawal distress and bodily strategies aimed to cope with is unknown. CRF-like signaling is transmitted by two receptor pathways, termed CRF(1) and CRF(2). Here, we report that CRF(2) receptor-deficient (CRF(2)(-/-)) mice lack the dysphoria-like and the anhedonia-like states of opiate withdrawal. Moreover, in CRF(2)(-/-) mice opiate withdrawal does not increase the activity of brain dynorphin, CRF and periaqueductal gray circuitry, which are major substrates of opiate withdrawal distress. Nevertheless, CRF(2) receptor-deficiency does not impair brain, neuroendocrine and autonomic stress-coping responses to opiate withdrawal. The present findings point to the CRF(2) receptor pathway as a unique target to relieve opiate withdrawal distress without impairing stress-coping abilities.
