As this study proposed an astrocytic contribution to DA cell death in PD, we generated iPSC-derived astrocytes from two PD patients carrying the G2019S mutation in the LRRK2 gene, one of them presenting with an additional mutation in GBA (p.N370S)16 to further characterize the PD astrocyte phenotype. This evidence concerns the gene LRRK2 and Parkinson disease.
