The involvement of specific medium spiny neuro (MSN) subtype and of other striatal cell types remains poorly understood. To gain insight into cell type-specific disease processes, researchers studied the nuclear transcriptomes of 4524 cells from the striatum of a genetically precise knock-in mouse model of the Huntington's Disease (HD) mutation, HttQ175/1. Three 14-month-old and one 15-month-old male mice were used to generate the primary dataset.
