Abstract
Antidepressants including paroxetine, fluoxetine and desipramine are commonly used for treating depression. P2Ã7 receptors are member of the P2X family. Recent studies indicate that these receptors may constitute a novel potential target for the treatment of depression. In the present study, we examined the action of these antidepressants on cloned rat P2Ã7 receptors that were stably expressed in human embryonic kidney (HEK) 293 cells by using the whole-cell patch-clamp technique, and found that paroxetine at a dose of 10 µM could significantly reduce the inward currents evoked by the P2Ã7 receptors agonist BzATP by pre-incubation for 6-12 but not by acute application (10 µM) or pre-incubation for 2-6 h at a dose of 1 µM, 3 µM or 10 µM paroxetine. Neither fluoxetine nor desipramine had significant effects on currents evoked by BzATP either applied acutely or by pre-incubation at various concentrations. These results suggest that the sensitivity of rat P2Ã7 receptors to antidepressants is different, which may represent an unknown mechanism by which these drugs exert their therapeutic effects and side effects.
