In the present study, N-methyl-D-aspartate receptor 2B (NR2B)-specific siRNA was applied in parkinsonian models. Our previous results showed that reduction in expression of N-methyl-D-aspartate receptor 1 (NR1), the key subunit of N-methyl-D-aspartate receptors, by antisense oligos ameliorated the motor symptoms in the 6-hydroxydopamine (6-OHDA)-lesioned rat, an animal model of Parkinson's dise...

Neuronal cell suspensions were implanted into the striatum of female rats that showed apomorphine-induced rotation and a reduction in striatal dopamine after intranigral treatment with 6-hydroxydopamine. The apomorphine-induced rotation was significantly suppressed by the transplantation in 12 out of 64 rats. DOPA accumulation and dopamine level (6.3 and 3.4%, respectively, compared with those ...

This review summarizes published results that are related to the coupling between the dopaminergic and the serotonergic systems and their association to Parkinson’s disease. We focus on the 6-hydroxydopamine rat model of Parkinson’s disease to better understand how dopamine dysfunction affects the serotonergic system, and furthermore to investigate whether a bidirectional coupling exists and ho...
