This research profiles the epigenomic landscape of the adult human central nervous system using single-nucleus sequencing to map chromatin accessibility and histone modifications. By analyzing various brain regions and the spinal cord, the authors identified a persistent epigenetic memory of developmental programs within adult glial cells, specifically oligodendrocytes. While these signatures do not always correlate with active gene expression, they appear to prime cells for regenerative responses or, conversely, increase vulnerability to certain types of brain tumors. The study provides a comprehensive multimodal resource that details how different cell populations, such as neurons and astrocytes, maintain distinct regulatory environments. Ultimately, these findings reveal how chromatin architecture and histone marks influence both the functional plasticity and the disease susceptibility of the mature human nervous system.
