The effects of antidepressant treatment on serotonergic and dopaminergic systems in Fawn-Hooded rats: a quantitative autoradiography study

Abstract

Fawn-Hooded (FH) rats exhibit a phenotype including depressive behaviour and high alcohol preference, and as such tricyclic antidepressants and selective serotonin reuptake inhibitors (SSRIs) reduce alcohol consumption in this rat strain [Psychiatr. Genet. 12 (2002) 1-16]. However, the neurochemical effects of these antidepressants on monoamine systems in the brain, especially in mesolimbic areas have not been studied in FH rats. Therefore, the present study investigated neurochemical effects of subchronic treatment (10 days) with desipramine (DMI) and sertraline on several neurochemical markers of serotonin and dopamine systems. Binding to these markers including dopamine transporters (DATs..
