Abstract: Objective To establish long lasting changes of motor function in MPTP-induced non-human primate models for investigating neuroprotective therapy. We try to study the dynamic changes of motor function of MPTP-induced unilateral Parkinson's disease model in cynomolgus monkeys. Methods Total 5 healthy male cynomolgus monkeys (6~7 years old) were injected MPTP into the left internal carotid artery. The motor behavior changes were evaluated by clinical rating score and physical activity monitoring before and after MPTP injection at 3 and 6 months, 1, 3, and 6 years. Results The clinical rating score was significantly increased and reached the peak (14.65±8.41) at 3 months and partially recovered at 6 months (8.10±2.01, P=0.006), but maintained stable to 6 years after MPTP injection. The 24 h physical activity was significantly decreased and reached the peak at 3 months (16 597.79±12 488.87, P=0.014), 6 months (29 278.02±12 264.66, P=0.016) but recovered to the baseline level (50 084.20±30 170.89) after 1 year. Conclusion The results suggest that the motor deficit assessed by clinical rating score of MPTP-induced unilateral Parkinson's disease model in cynomolgus monkeys can last up to 6 years.
