Addiction is a chronic, frequent and serious brain disease, with relapse alternating with abstinence periods. Epidemiological studies show that abstinence, notably from opiates, is strongly associated with depression.Here we present the main clinical aspects of opiate addiction and depression, and most recent advances in molecular pathophysiology of both disorders. Then, we present our mouse model of opiate abstinence. Following chronic morphine exposure, depressive-like behaviours progressively emerge. Morphine treatment profoundly disrupts serotonergic signalling, notably in the dorsal raphe nucleus. In addition, behavioural deficits can be prevented by chronic treatment with fluoxetine, an antidepressant targeting serotonergic neurons. W...
