TY - JOUR TI - Selective suppression of oligodendrocyte-derived amyloid beta rescues neuronal dysfunction in Alzheimer's disease AV - public Y1 - 2024/07// EP - 30 N2 - Reduction of amyloid beta (A?) has been shown to be effective in treating Alzheimer?s disease (AD), but the underlying assumption that neurons are the main source of pathogenic A? is untested. Here, we challenge this prevailing belief by demonstrating that oligodendrocytes are an important source of A? in the human brain and play a key role in promoting abnormal neuronal hyperactivity in an AD knock-in mouse model. We show that selectively suppressing oligodendrocyte A? production improves AD brain pathology and restores neuronal function in the mouse model in vivo. Our findings suggest that targeting oligodendrocyte A? production could be a promising therapeutic strategy for treating AD.
