Dopamine receptor plasticity following MPTP-induced nigrostriatal lesions in the mouse

Eur J Pharmacol. 1990 May 16;180(2-3):369-72. doi: 10.1016/0014-2999(90)90324-y.

Abstract

MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) destroys dopamine-containing nigrostriatal neurons and increases the apparent Bmax of both D1 and D2 binding sites in the striatum. However, the changes of Bmax occur at different intervals after the lesion. Up-regulation of D2 sites becomes evident about 3 weeks after the lesion and lasts for about 3 months. In contrast, about 3 months are required for the up-regulation of D1 sites and increased binding is still evident after 5 months.
