The vesicular monoamine transporter-2 (VMAT-2) is principally involved in regulating cytoplasmic dopamine (DA) concentrations within terminals by sequestering free DA into synaptic vesicles. This laboratory previously identified a correlation between striatal vesicular DA uptake through VMAT-2 and inhibition of the DA transporter (DAT). For example, administration of methylphenidate (MPD), a DAT inhibitor, increases vesicular DA uptake through VMAT-2 in a purified vesicular preparation; an effect associated with a redistribution of VMAT-2 protein within DA terminals. The purpose of this study was to determine if other DAT inhibitors, including bupropion, similarly affect VMAT-2. Results revealed bupropion rapidly, reversibly, and dose-dependently increased vesicular DA uptake; an effect also associated with VMAT-2 protein redistribution. The bupropion-induced increase in vesicular DA uptake was prevented by pretreatment with eticlopride, a DA D2 receptor antagonist, but not by SCH23390, a DA D1 receptor antagonist. We previously reported that MPD post-treatment prevents persistent DA deficits associated with multiple methamphetamine (METH) administrations. Although bupropion attenuated the METH-induced reduction in VMAT-2 activity acutely, it did not prevent the long-term dopaminergic toxicity or the METH-induced redistribution of VMAT-2 protein. The findings from this study demonstrate similarities and differences in the mechanism by which MPD and bupropion affect striatal dopaminergic nerve terminals.
