Genetic interventions for inducing PD in NHPs include injection of viral vectors encoding for overexpression of α-synuclein and LRRK2 (autosomal-dominant genes) and knockout or knockdown models for PINK1, Parkin, and DJ-1 (autosomal-recessive genes) [42,43,44,45,46]. This evidence concerns the gene SNCA and Parkinson disease.
