Oligodendrocyte dysfunction in human age-related cognitive decline.
Nature medicine·August 25, 2026·PMID 42642661
Why it mattersAge-related cognitive decline lacks effective treatments, and this work identifies a specific cellular pathway—oligodendrocyte NRF2—that may explain individual variability in cognitive aging. For clinicians focused on aging and cognitive performance, these findings suggest a novel biological mechanism that could eventually inform risk stratification or targeted interventions.
