The repository includes Spatial Transcriptomic datasets generated by Nanostring GeoMx (Hu WTA) analysis of midbrain TH+ cells from Controls (n=10), Incidental Lewy Body Disease (n=10), early Parkinsons Disease (ePD,n=5) and late Parkinsons Disease (lPD,n=5). A total 348 Regions of Interest were analysed. The raw and processed counts and metadata are provided as an R Seurat object (geomx_edwards_thmask.rds). The scripts used for low level data processing are described in https://github.com/zchatt/ASAP-SpatialTranscriptomics/blob/main/geomx/lowlevel/README.md Tissue samples from pathologically confirmed asymptomatic stage I-II Lewy body disease, stage IV Lewy body PD (early-PD), stage VI Lewy body PD (late-PD)(Braak, Del Tredici et al. 2003) and controls without the neurological or neuropathological disease were obtained from the Sydney Brain Bank. The study was approved by the University of Sydney Human Research Ethics Committee (2021/845). All cases with PD were levodopa-responsive and fulfilled the UK Brain Bank Clinical Criteria for a diagnosis of clinical PD (Hughes, Ben-Shlomo et al. 1992) with no other neurodegenerative conditions. Cells were not extracted. Tissue sections...
