Oligomeric amyloid-β (Aβ) peptide causes synaptic dysfunction, accumulates within synapses, and has been associated with synapse loss around plaques in Alzheimer’s disease (AD). However, there is a need to identify synaptic binding partners of Aβ that mediate synaptotoxicity in the brain. A team of investigators from the University of Edinburgh and affiliated organizations aimed to identify synaptic receptors that bind Aβ in human AD.
