We sought to gain insight into enteric nervous system function in Thy1-ASO mice by isolating neuronal nuclei from mouse intestines, which makes up less than 1% of cells, followed by transcriptomic analysis. To overcome the challenge of profiling gene expression in rare cell populations within complex tissues, we engineered an adeno-associated virus (AAV) that expresses a fluorescent protein in the nuclear membrane under the control of a constitutive neuronal promoter. We generated a high-quality single-nuclei gene expression dataset that revealed transcriptional heterogeneity reflecting populations of 4 putative excitatory motor neuron subtypes, 2 putative inhibitory motor neuron subtypes, 3 putative interneuron subtypes, and a putative sensory neuron gene cluster. There was little difference in expression of individual genes in neurons between wild-type and Thy1-ASO mice in the colon, under the conditions tested. However, pathway analysis revealed changes in the PI3K pathway in excitatory motor neurons (upregulated in Thy1-ASO), MAPK and androgen pathways in inhibitory motor neurons (upregulated in Thy1-ASO), and WNT (upregulated in Thy1-ASO) and p53 (downregulated in Thy1-ASO) pathways in interneurons. This dataset can be leveraged to understand the physiological basis of gut motility deficits in α-synuclein overexpressing mice.</description><dates><publication>2026/06/30</publication></dates><accession>GSE297092</accession><cross_references><GSM>GSM8983574</GSM><GSM>GSM8983573</GSM><GSM>GSM8983572</GSM><GSM>GSM8983571</GSM><GSM>GSM8983570</GSM><GSM>GSM8983569</GSM><GSM>GSM8983568</GSM><GSM>GSM8983567</GSM><GPL>34290</GPL><GSE>297092</GSE><taxon>Mus musculus</taxon></cross_references></HashMap>
