Parkinson's disease(PD)is a neurodegenerative disease,leading to the impairment of movement *** pathogenesis has been largely investigated,either limited to bulk transcriptomic levels or at certain cell types,which failed to capture the cellular heterogeneity and intrinsic interplays among distinct cell ***,we report the application of single-nucleus RNA-seq on midbrain,striatum,and cerebellum of theα-syn-A53 t mouse,a well-established PD mouse model,and matched controls,generating the first single cell transcriptomic atlas for the PD model mouse brain composed of 46,174 individual ***,we comprehensively depicte the dysfunctions in PD pathology,covering the elevation of NF-k B activity,the alteration of ion channel components,the perturbation of protein homeostasis network,and the dysregulation of glutamatergic ***,we identify a variety of cell types closely associated with PD risk *** together,our study provides valuable resources to systematically dissect the molecular mechanism of PD pathogenesis at the single-cell resolution,which facilitates the development of novel approaches for diagnosis and therapies against PD.
