چکیده انگلیسی
Preclinical studies indicate that the rapid antidepressant effect of ketamine is dependent on activation of AMPA receptors in the medial prefrontal cortex (mPFC) resulting in a prolonged enhancement of glutamatergic transmission in the mPFC. In similarity, addition of atypical antipsychotic drugs (APDs) to SSRIs has also been found to induce a rapid and potent antidepressant effect. Using intracellular recordings in layer V/VI pyramidal cells of the rat mPFC in vitro, we found that a combination of low, clinically relevant concentrations of the atypical APD olanzapine and the SSRI fluoxetine facilitated NMDA and AMPA-induced currents in pyramidal cells via activation of dopamine D1 receptors. A single ketamine injection (10Â mg/kg, 24Â h before the experiment) enhanced AMPA-and apparently to some extent also NMDA-induced currents. Our results propose that the rapid and potent antidepressant effects of both treatments may be related to a common mechanism of action, namely facilitation of glutamatergic, in particular AMPA receptor-mediated transmission, in the mPFC.
