Super-resolved spatial transcriptomics reveals early hippocampal RNA localization changes in a mouse model of Alzheimer’s disease Open
Summary Cell-type-specific changes in gene expression and RNA localization are hallmarks of Alzheimer’s disease (AD) and other neurodegenerative disorders, yet spatial dysregulation in early disease stages remains poorly defined. Here, we …
