title: Regulation of Striatal N-Methyl-D-Aspartate Receptor (NMDAR) Function by Phosphorylation of its Subunits in Parkinsonian Rats.
abstract: The cardinal signs of Parkinson's disease (PD) reflect striatal dopamine depletion due to the progressive degeneration of neurons arising from the substantia nigra. Initially, treatment with the dopamine precursor levodopa ordinarily confers substantial clinical benefit. Later, however, increasing difficulties arise mainly due to the appearance of motor response fluctuations and dyskinesias complicating the treatment of late-stage PD (1-6). Available evidence suggests that standard dopaminomimetic treatment regimens promote the intermittent activation of striatal dopaminergic receptors, which under normal conditions operate mainly tonically (7), and that this nonphysiologic stimulation favors the appearance of the motor fluctuations and dyskinesias (8).
