Abstract

Studying Parkinson's disease (PD) is complex due to a lack of cellular models mimicking key aspects of protein pathology. Here, we present a protocol for inducing and monitoring α-synuclein aggregation in living cells using optogenetics. We describe steps for plasmid transduction, biochemical validation, immunocytochemistry, and live-cell confocal imaging. These induced aggregates fulfill the cardinal features of authentic protein inclusions observed in PD-diseased brains and offer a tool to study the role of protein aggregation in neurodegeneration. For complete details on the use and execution of this protocol, please refer to Bérard et al.1.
