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 کاملAttenuated neurodegenerative disease phenotype in tau transgenic mouse lacking neurofilaments.
Previous studies have shown that transgenic (Tg) mice overexpressing human tau protein develop filamentous tau aggregates in the CNS. The most abundant tau aggregates are found in spinal cord and brainstem in which they colocalize with neurofilaments (NFs) as spheroids in axons. To elucidate the role of NF subunit proteins in tau aggregate formation and to test the hypothesis that NFs are patho...
متن کاملTau and neurodegenerative disorders.
The mechanisms that render tau a toxic agent are still unclear, although increasing evidence supports the assertion that alterations of tau can directly cause neuronal degeneration. In addition, it is unclear whether neurodegeneration in various tauopathies occurs via a common mechanism or that specific differences exist. The aim of this review is to provide an overview of tauopathies from benc...
متن کاملTau mutations in neurodegenerative diseases.
Tau deposition is found in a variety of neurodegenerative brain diseases. The identification of tau mutations that cause familial dementia demonstrated that aberrant Tau alone could cause neurodegenerative disease and suggested that Tau likely plays a role in other cases in which Tau deposits are found, most notably Alzheimer disease. The mechanisms by which tau mutations cause neurodegeneratio...
متن کاملTau phosphorylation: the therapeutic challenge for neurodegenerative disease.
The microtubule-associated protein tau is integral to the pathogenesis of Alzheimer's disease (AD), as well as several related disorders, termed tauopathies, in which tau is deposited in affected brain regions. In the tauopathies, pathological tau is in an elevated state of phosphorylation and is aberrantly cleaved. It also exhibits abnormal conformations and becomes aggregated, resulting in ne...
