伪-Synuclein (伪-Syn) accumulation has a significant role in Parkinson's disease (PD).
伪-Syn protein sequence is well conserved across species.
Nigral 伪-syn distribution in monkeys changes with age or toxin exposure.
Viral vector gene transfer of wild type or mutated 伪-syn induces neurodegeneration.
Novel PD monkey models are being generated using inoculations of 伪-syn and transgenesis.
