This research article from Nature Neuroscience investigates the epigenetic landscape of the adult human central nervous system at a single-nucleus level. By analyzing chromatin accessibility and specific histone modifications, researchers identified a specialized epigenetic memory in oligodendroglia and astrocytes that mirrors early developmental stages. These unique signatures, particularly at HOX gene loci, remain present in adulthood even when the genes are not actively being expressed. The study suggests that while this priming allows for rapid gene activation during tissue repair, it may…
