Synapse loss occurs early in Alzheimer's disease (AD) and is considered the best pathological correlate of cognitive decline. Ephrins and Eph receptors are involved in regulation of excitatory neurotransmission and play a role in cytoskeleton remodeling. We asked whether alterations in Eph receptors could underlie cognitive impairment in an AD mouse model(More)
The amyloid-beta peptide cascade hypothesis has provided a useful framework for the research on Alzheimer's disease for nearly 20 years. According to this hypothesis, an increase in amyloid-beta levels triggers all of the pathological features of the disease, including tau hyperphosphorylation, appearance of neurofibrillary tangles, synaptic dysfunction and(More)
