Alzheimer's disease A� assemblies mediating rapid disruption of synaptic plasticity and memory.
(2012)Alzheimer’s disease (AD) is characterized by episodic memory impairment that often precedes clinical diagnosis by many years. Probing the mechanisms of such impairment may provide much needed means of diagnosis and therapeutic ... -
Amyloid-β protein dimers isolated directly from Alzheimer's brains impair synaptic plasticity and memory.
(2008)Alzheimer?s disease (AD) constitutes a rising threat to public health. Despite extensive research in cellular and animal models, identifying the pathogenic agent present in the human brain and showing that it confers key ... -
Exosomes neutralize synaptic-plasticity-disrupting activity of Aß assemblies in vivo.
(2013)Abstract BACKGROUND: Exosomes, small extracellular vesicles of endosomal origin, have been suggested to be involved in both the metabolism and aggregation of Alzheimer's disease (AD)-associated amyloid β-protein (Aβ). ... -
GluN2B subunit-containing NMDA receptor antagonists prevent Abeta-mediated synaptic plasticity disruption in vivo
(2009)Currently, treatment with the relatively low-affinity NMDA receptor antagonist memantine provides limited benefit in Alzheimer's disease (AD). One probable dose-limiting factor in the use of memantine is the inhibition of ... -
Glutamate receptors in preclinical research on Alzheimer's disease: update on recent advances
(2012)The cognitive and related symptoms of Alzheimer's disease are mainly attributable to synaptic failure. Here we review recent research on how the Alzheimer's disease amyloid ?-protein (A?) affects glutamate receptors and ... -
Interaction between prion protein and toxic amyloid ß assemblies can be therapeutically targeted at multiple sites.
(2011)A role for PrP in the toxic effect of oligomeric forms of A?, implicated in Alzheimer's disease (AD), has been suggested but remains controversial. Here we show that PrP is required for the plasticity-impairing effects of ... -
Patient-derived tau and amyloid-beta facilitate long-term depression in vivo: role of tumor necrosis factor alpha and the integrated stress response
(2024)Alzheimer’s disease is characterized by progressive cognitive decline in older individuals accompanied by the deposition of two pathognomonic proteins amyloid β (Aβ) and tau. It is well documented that synaptotoxic soluble ... -
Physiological activation of mGlu5 receptors supports the ion channel function of NMDA receptors in hippocampal LTD induction in vivo
(2018)Synaptic long-term depression (LTD) is believed to underlie critical mnemonic processes in the adult hippocampus. The roles of the metabotropic and ionotropic actions of glutamate in the induction of synaptic LTD by ... -
Remodelling by early-life stress of NMDA receptor-dependent synaptic plasticity in a gene-environment rat model of depression.
(2009)An animal model of depression combining genetic vulnerability and early-life stress (ELS) was prepared by submitting the Flinders Sensitive Line (FSL) rats to a standard paradigm of maternal separation. We analysed hippocampal ... -
Switching off LTP: mGlu and NMDA receptor-dependent novelty exploration-induced depotentiation in the rat hippocampus.
(2013)Both electrically induced synaptic long-term potentiation (LTP) and long-term depression have been extensively studied as models of the cellular basis of learning and memory mechanisms. Recently, considerable interest has ...
