Abstract
The accumulation of amyloid -protein (Aβ) plaques is identified as a major pathological feature of Alzheimer’s disease(AD). Recent studies show that soluble species of Aβare involved in the early memory dysfunction long before neurodegenerativechanges. However, the mechanism underlying the neurotoxicity of soluble Aβis still unclear. Long-term potentiation (LTP) has beenthought as an important cellular model of synaptic plasticity for many years. The studies on the hippocampal LTP and Aβ, especiallythose using AD transgenic models, provided more evidence for the Aβ-induced dysfunction of learning and memory. Based on the recentresearches on AD, this article reviewed the effects of Aβ, especially soluble Aβ and its active fragments, on the hippocampal LTP. Thepossible mechanisms by which Aβimpairs hippocampal LTP are also discussed.
