Aβ Oligomer-Induced Aberrations in Synapse Composition, Shape, and Density Provide a Molecular Basis for Loss of Connectivity in Alzheimer's Disease
Pascale N. Lacor,Maria C. Buniel,Paul W. Furlow,Antonio Sanz Clemente,Pauline T. Velasco,Margaret Wood,Kirsten L. Viola,William L. Klein +7 more
TL;DR: The observed disruption of dendritic spines links ADDLs to a major facet of AD pathology, providing strong evidence that AD DLs in AD brain cause neuropil damage believed to underlie dementia.
Journal ArticleDOI
Synaptic Targeting by Alzheimer's-Related Amyloid β Oligomers
Pascale N. Lacor,Maria C. Buniel,Lei Chang,Sara J. Fernandez,Yuesong Gong,Kirsten L. Viola,Mary P. Lambert,Pauline T. Velasco,Eileen H. Bigio,Caleb E. Finch,Grant A. Krafft,William L. Klein +11 more
TL;DR: The hypothesis that targeting and functional disruption of particular synapses by Aβ oligomers may provide a molecular basis for the specific loss of memory function in early Alzheimer's disease is suggested.
Journal ArticleDOI
Aβ Oligomers Induce Neuronal Oxidative Stress through an N-Methyl-D-aspartate Receptor-dependent Mechanism That Is Blocked by the Alzheimer Drug Memantine
Fernanda G. De Felice,Fernanda G. De Felice,Pauline T. Velasco,Mary P. Lambert,Kirsten L. Viola,Sara J. Fernandez,Sergio T. Ferreira,William L. Klein +7 more
TL;DR: This response provides a pathologically specific mechanism for the therapeutic action of memantine, indicates a role for ROS dysregulation in ADDL-induced cognitive impairment, and supports the unifying hypothesis that ADDLs play a central role in AD pathogenesis.
Journal ArticleDOI
Protection of synapses against Alzheimer's-linked toxins: Insulin signaling prevents the pathogenic binding of Aβ oligomers
Fernanda G. De Felice,Marcelo N. N. Vieira,Theresa R. Bomfim,Helena Decker,Pauline T. Velasco,Mary P. Lambert,Kirsten L. Viola,Wei Qin Zhao,Sergio T. Ferreira,William L. Klein +9 more
TL;DR: The finding that synapse vulnerability to ADDLs can be mitigated by insulin suggests that bolstering brain insulin signaling, which can decline with aging and diabetes, could have significant potential to slow or deter AD pathogenesis.
Journal ArticleDOI
Self-assembly of Aβ1-42 into globular neurotoxins
Brett A. Chromy,Richard Nowak,Mary P. Lambert,Kirsten L. Viola,Lei Chang,Pauline T. Velasco,Bryan W. Jones,Sara J. Fernandez,Pascale N. Lacor,Peleg M. Horowitz,Caleb E. Finch,Grant A. Krafft,William L. Klein +12 more
TL;DR: Aβ 1−42 (Aβ1-42) is a self-associating peptide that becomes neurotoxic upon aggregation as discussed by the authors, and its toxicity originally was attributed to the presence of large, readily formed Aβ fibrils.
