Manganese (Mn) is an essential nutrient, though exposure to high concentrations may result in neurotoxicity characterized by alterations in dopamine neurobiology. To date, it remains elusive how and why Mn targets dopaminergic neurons although recently the role of the dopamine transporter has been suggested. Our primary goal of this study was to examine the potential roles of the monoamine transporters, dopamine transporter (DAT), serotonin transporter (SERT) and norepinephrine transporter (NET), in neuronal Mn transport. Using striatal synaptosomes, we found that only inhibition of DAT significantly decreased Mn accumulation. Furthermore, weanling rats chronically exposed to Mn, significantly accumulated Mn in several brain regions. However, rats receiving the specific DAT inhibitor GBR12909 (1 mg/kg bw, three times/week; four weeks) had significantly lower Mn levels only in the globus pallidus compared to saline-treated rats (p<0.05). Our data show that inhibition of DAT exclusively inhibits Mn accumulation in the globus pallidus during chronic exposure.
