Genes associated with lysosomal dysfunction increase the risk of Parkinson’s disease (PD), according to a study led by scientists at Northwestern University. The discovery also explains why some people who carry a pathogenic variant of the GBA1 gene develop PD or dementia with Lewy bodies (DLB) and others do not. The key lies in the Commander complex, involved in the transport of proteins to this organelle. This discovery raises the need for combinatorial therapies that act on more than one pathway for this type of neurodegenerative disorder.
