C-terminal fragment of N-cadherin accelerates synapse destabilization by amyloid-β.

The aetiology of Alzheimer's disease is thought to include functional impairment of synapses and synapse loss as crucial pathological events leading to cognitive dysfunction and memory loss. Oligomeric amyloid-β peptides are well known to induce functional damage, destabilization and loss of brain synapses. However, the complex molecular mechanisms of amyloid-β action resulting ultimately in synapse elimination are incompletely understood, thus limiting knowledge of potential therapeutic targets.
