    Maladaptive interactions between microglia and T lymphocytes contribute to white matter changes associated with aging and neurodegenerative diseases.

  • 2

    Aging alters microglial signaling and promotes CD8+ T cell recruitment through cytokine signaling, impacting myelin preservation.

  • 3

    Interferon-gamma from T cells induces transcriptional changes in microglia and oligodendrocyte lineage cells, destabilizing myelin.

  • 4

    White matter changes correlate with cognitive decline and increased dementia risk, highlighting the significance of myelin integrity.

  • 5

    Genetic studies reveal that glial cell regulatory elements are central to white matter pathology, linking genetic variations to brain disease.
