Altered expression of α-synuclein is linked to Parkinson's disease (PD). A major challenge to explore how the increased α-synuclein affect neurotoxicity is the lack of a suitable human neuronal cell model that mimics this scenario. Its expression in neural precursors affects their differentiation process, in addition to the neuronal adaptability and variability in maintaining a constant level of expression across passages. Here, we describe an SH-SY5Y line harboring Tet-ON SNCA cDNA cassette that allows for induction of controlled α-synuclein expression after neuronal differentiation, which can be an important tool for PD research.
