PLOSJul 23 2024 Oligodendrocytes are an important source of amyloid beta and play a key role in promoting neuronal dysfunction in Alzheimer's disease , according to a study published July 23, 2024 in the open-access journal PLOS Biology by Rikesh Rajani and Marc Aurel Busche from the UK Dementia Research Institute at University College London, and colleagues.
In the study, Rajani and Busche showed that non-neuronal brain cells called oligodendrocytes produce Aβ. They further demonstrated that selectively suppressing Aβ production in oligodendrocytes in an AD mouse model is sufficient to rescue abnormal neuronal hyperactivity. The results provide evidence for a critical role of oligodendrocyte-derived Aβ for early neuronal dysfunction in AD.
