A Transcriptomic Roadmap of Parkinson's Disease Progression at Single Cell Resolution.

ABSTRACT: Parkinson's disease (PD) is a progressive neurodegenerative disorder with complex and heterogeneous molecular pathology across the brain. However, the full cellular architecture of PD progression remains unresolved. Here, we present a comprehensive single-nucleus transcriptomic atlas of PD spanning multiple anatomically and clinically relevant brain regions to capture shared and region-influenced transcriptomic features from 97 deeply phenotyped donors, including individuals across the full spectrum of Braak Lewy body stages. Profiling over 2 million nuclei, we define 62 transcriptionally distinct cell subtypes and uncover widespread, cell-type-specific gene expression changes across neurons, glia, and vascular cells. We identify convergent upregulation of stress-responsive transcriptional
