    Abstract:
    Systemic injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) is known to damage the dopaminergic nigrostriatal system in C57BL/6 mice. We have investigated the effects of immunosuppressants, FK-506 and cyclosporin A (CsA), on MPTP-induced dopamine (DA) depletion in the striatum of young C57BL/6 mice. 10 days after MPTP treatment (25 mg/kg i.p. given daily, 5 days), DA in the striatum was depleted by 80%. However, pretreatment with FK-506, a novel immunosuppressant, significantly protected MPTP-induced DA depletion in the striatum, but FK-506 itself did not affect the DA content. CsA, another immunosuppressant, also protected MPTP-induced DA depletion. From these results can be seen that immunosuppressants seem to inhibit MPTP neurotoxicity toward nigrostriatal dopaminergic neurons of young C57BL/6 mice.
