Abstract:
Age-related changes in oligodendrocyte precursor cells (OPCs) contribute to white matter dysfunction. In aged mice, we hypothesized that myelin-dense fimbria OPCs possess niche-specific properties, compared to hippocampal OPCs. Aged fimbria OPCs were fewer, larger, and localized to neighboring microglia. We identified age-increased p16/Cdkn2a-expressing OPCs enriched for senescence-related pathways and distinct senescence signatures between hippocampus and fimbria. Aged brain OPC populations differ in microenvironment properties and responses to senescence-directed intervention.
