Relationship between potencies of antidepressants for the blockade of Kir4.1 channels and for the astrocytic BDNF induction. (A) Inhibition percentage (IDrug/IControl) of Kir4.1-conducted currents by sertraline (30 μM), fluoxetine (30 μM), imipramine (100 μM), fluvoxamine (100 μM), or mianserin (100 μM) in HEK293T cells. (B) Enhancement of BDNF mRNA expression by sertraline, fluoxetine, imipramine, fluvoxamine, or mianserin in astrocytes. Astrocytes were treated with each antidepressant (30 μM) for 8 h and the BDNF mRNA expression was analyzed by RT-PCR. The BDNF mRNA levels are expressed as the ratio to GAPDH mRNA. Each point represents the mean ± SEM of six separate experiments. P < 0.05, significantly different from the astrocytes treated with vehicle.
