Daim ntawv thov:
- Oxidative stress thiab mitochondrial tsis ua haujlwm
- Thaum ntxov-kev tshawb nrhiav kab mob theem
- Txawm hais tias cov qauv caj ces qhia meej txog cov txheej txheem molecular, lawv cov kev hloov kho kho mob tseem txwv. Rau kev kho mob ntawm tes thiab biologics siab heev, NHP qauv muab cov txiaj ntsig zoo dua.
3. Nonhuman Primates: Tus Txheej Txheem Kev Txhais Lus Kub rau PD Kev Tshawb Fawb
NHPs-tshwj xeeb tshaj yogcynomolgusthiabrhesus liab-yog hom kab mob ze tshaj plaws rau tib neeg nyob rau hauv cov nqe lus ntawm basal ganglia anatomy, neural circuitry, thiab cwj pwm phenotypes. Lawv raug lees paub thoob ntiaj teb raws li covkub standardrau kev soj ntsuam kev kho mob ntawm tes, kev kho kab mob kis kab mob, thiab biologics tsom rau CNS.
Txoj Kev Ua Qauv
Txoj kev qhia pom zoomob MPTP inductionkom ua raws li kev loj hlob dopaminergic degeneration thiab ntev - lub sij hawm ua haujlwm poob.
Kev ntsuam xyuas Framework
Kev ntsuam xyuas dav dav yog qhov tseem ceeb rau kev kho mob txhais lus:
- Kurlan Rating Nplai:Quantifies tremor, bradykinesia, posture, thiab gait
