Patient-derived cells and brain organoids uncover treatment targets in Parkinson’s disease

Mutations in PARK7 lead to the development of early-onset Parkinson’s disease (PD). The authors of this study identified an exonic splicing mutation in PARK7 linked to PD and studied the effect of this mutation in patient-derived cellular models. The mutation resulted in impaired splicing, reduced production of DJ-1 protein, and consequent mitochondrial dysfunction. Using precise bioinformatics algorithms, the researchers performed an automated drug screen and identified a combination of two substances that rescued the aberrant splicing and neuronal loss in patient-derived brain organoids. The results suggest that precision medicine targeting specific molecular signatures could be an effective strategy for PD and possibly other neurodegenerative diseases.
