Progressive supranuclear palsy (PSP) is a neurodegenerative disorder whose molecular complexity at a single cell level has not been evaluated. Here we analyzed 45,559 high quality nuclei from the subthalamic nucleus and associated basal ganglia regions from post-mortem human PSP brains with varying degrees of tau pathology compared to controls (n=3 per group). We identified novel astrocyte-oligodendrocyte hybrid cell populations that overexpress neurotropic factors in conjunction with suppression of the unfolded protein response pathway. Notably, trajectory analysis identified subpopulations of hybrid cells with distinct astrocytic, oligodendrocytic and hybrid molecular states that change from a neuroprotective hybrid cell to an astrocytic cell with impaired homeostatic function in PSP. Our single nucleus transcriptomic data provides insights into the cell-type-specific contributions to the disease for investigating the molecular and cellular basis of PSP.
