Oligodendrocytes identified as key amyloid β producers in Alzheimer's disease

Researchers discovered that oligodendrocytes, not just neurons, produce amyloid β in Alzheimer's disease, and suppressing their activity improves disease pathology. This finding suggests new therapeutic targets for Alzheimer's treatment.
