It is shown that amyloid-β oligomers interact with the receptor tyrosine kinase EphB2 and trigger its degradation. EphB2 regulates NMDA-type glutamate receptors and its depletion in normal mice reduces NMDA receptor currents and impairs long-term potentiation, both of which are important for memory formation. Increasing EphB2 levels in a mouse model of Alzheimer's disease improves memory.
