Since that publication, the findings have been confirmed in LCLs from a larger cohort of idiopathic PD patients (unpublished data) and in other cellular PD models, including exposure of the neuroblastoma cell line SH–SY5Y to fibrillar alpha–synuclein [73] and in the simple eukaryotic model Dictyostelium discoideum, expressing genetically manipulated PD-associated genes, including α-synuclein [74] and DJ-1 [75]. Here, PARK7 is linked to Parkinson disease.
