Adult neurogenesis plays an important role in brain function and declines with aging. A recent report demonstrates clonal T cell expansion within neurogenic niches of the aged brain, impairing neurogenesis through IFNγ signaling (Dulken et al., Nature, 2019). These results highlight T cells as important contributors to and potential therapeutic targets for age-related brain dysfunction.
