Mapping Millions of Aging Brain Cells Simultaneously

By developing IRISeq and EnrichSci, researchers can now map the spatial neighborhoods of millions of aging brain cells and zoom in on rare, vulnerable populations. Their discovery that inflammatory cells cluster in white matter and that exonic changes drive oligodendrocyte aging provides precise new targets for anti-aging interventions and neurodegenerative disease treatment.
