Lentiviral Transduction of Neural Progenitor Cells for Epigenetic Regulation of Alpha-Synuclein Expression

Executive Industry Relevance

This method enables precise epigenetic modulation of alpha-synuclein in human neural progenitor cells, supporting target validation in Parkinson's disease research. By reducing SNCA expression through dCas9-DNMT3A-mediated methylation, it provides a scalable system for de-risking therapeutic hypotheses and evaluating gene regulation strategies. The workflow supports early discovery efforts requiring mechanistic insight into epigenetic drivers of neurodegeneration.
