A primate nigrostriatal atlas of neuronal vulnerability and resilience in a model of Parkinson's disease

The degenerative process in Parkinson's disease (PD) causes a progressive loss of dopaminergic neurons (DaNs) in the nigrostriatal system. Resolving the differences in neuronal susceptibility warrants an amenable PD model that, in comparison to post-mortem human specimens, controls for environmental and genetic differences in PD pathogenesis. At present study, we generated a primate model of PD by carotid artery injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine MPTP and sampled substantia nigra and putamen of macaque for single cell sequencing analysis.
