A large body of evidence implicates beta-amyloid peptide (betaAP) and other derivatives of the evolutionarily highly conserved amyloid precursor protein (APP) in the pathogenesis of Alzheimer's disease. However, the functional relationship of APP and its proteolytic derivatives to synaptic plasticity is not well known. We demonstrate that 30 min exposure to the 25-35 fragment of betaAP do not markedly change the dynamics of synaptic responses in identified neurons of terrestrial snail while a significant decrease of long-term sensitization was observed after 180 min betaAP bath application. In the behavioral experiments, a significant reduction of sensitization, and decreased ability to develop food-aversion conditioning was observed after betaAP injection. Our results clearly demonstrate that the neurotoxic 25-35 fragment of betaAP may play a significant role in behavioral plasticity by chronically eliminating certain underlying forms of synaptic plasticity. The study also proposes a novel invertebrate model to Alzheimer's disease.
