Here, we challenge this prevailing belief by demonstrating that oligodendrocytes are an important source of A{\ensuremath{\beta}} 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{\ensuremath{\beta}} production improves AD brain pathology and restores neuronal function in the mouse model in vivo. Our findings suggest that targeting oligodendrocyte A{\ensuremath{\beta}} production could be a promising therapeutic strategy for treating AD.}, issn = {1544-9173}, author = {Rajani, Rikesh M and Ellingford, Robert and Hellmuth, Mariam and Harris, Samuel S and Taso, Orjona S and Graykowski, David and Lam, Francesca Kar Wey and Arber, Charles and Fertan, Emre and Danial, John SH and Swire, Matthew and Lloyd, Marcus and Giovannucci, Tatiana A and Bourdenx, Mathieu and Klenerman, David and Vassar, Robert and Wray, Selina and Sala Frigerio, Carlo and Busche, Marc Aurel}, url = {http://dx.doi.org/10.1371/journal.pbio.3002727}, keywords = {Science \& Technology, Life Sciences \& Biomedicine, Biochemistry \& Molecular Biology, Biology, Life Sciences \& Biomedicine - Other Topics, PLURIPOTENT STEM-CELLS, MOUSE MODEL, CORTEX, TRANSCRIPTOMICS, MYELINATION, INHIBITION, ASTROCYTES, PATHOLOGY, PLAQUES} }
