Why now
- Recent advances in single-cell and proteomic technologies enable detailed cellular phenotyping.
- Emerging gene therapy approaches for SMA highlight the need for mechanistic validation.
- Parkin mutation models provide a platform to dissect Parkinson's disease heterogeneity at single-cell resolution.
Why it matters
- Understanding astrocyte and neuron dysfunction in SMA could guide targeted therapies.
- Cell type-specific insights in Parkinson's disease may enable earlier intervention strategies.
- iPSC models allow study of early disease mechanisms not accessible in postmortem tissue.
