Tau oligomers and tau toxicity in neurodegenerative disease.
AD (Alzheimer's disease) is a progressive neurodegenerative disorder characterized by the extracellular accumulation of amyloid β-peptide and the intracellular accumulation of tau. Although there is much evidence linking tau to neurodegeneration, the precise mechanism of tau-mediated neurotoxicity remains elusive. The presence of tau-positive pre-tangle neurons lacking neurofibrillary tangles h...
متن کاملTau Phosphorylation, Aggregation, and Cell Toxicity
Protein aggregation takes place in many neurodegenerative disorders. However, there is a controversy about the possible toxicity of these protein aggregates. In this review, this controversy is discussed, focussing on the tau aggregation that takes place in those disorders known as tauopathies.
متن کاملNUB1 modulation of GSK3b reduces tau aggregation
Abnormal phosphorylation of the microtubule-associated protein tau in neurodegenerative disorders, including Alzheimer’s disease (AD) and frontotemporal lobar degeneration, is associated with disrupted axonal transport and synaptic dysfunction ultimately manifesting as histopathological lesions of protein aggregates. Glycogen synthase kinase 3b (GSK3b) may be critical for the pathological hyper...

متن کاملHsp70 Reduces alpha-Synuclein Aggregation and Toxicity.
Aggregation and cytotoxicity of misfolded alpha-synuclein is postulated to be crucial in the disease process of neurodegenerative disorders such as Parkinson's disease and DLB (dementia with Lewy bodies). In this study, we detected misfolded and aggregated alpha-synuclein in a Triton X-100 insoluble fraction as well as a high molecular weight product by gel electrophoresis of temporal neocortex...
