GSPE interferes with tau aggregation in vivo: implication for treating tauopathy.
Tauopathies are characterized by progressive neurodegeneration caused by intracellular accumulation of hyperphosphorylated tau protein aggregates in the brain. The present study was designed to test whether a grape seed polyphenolic extract (GSPE) previously shown to inhibit tau protein aggregation in vitro could benefit tau-mediated neuropathology and behavior deficits in JNPL3 transgenic mice...
متن کاملProteopathic tau seeding predicts tauopathy in vivo.
Transcellular propagation of protein aggregates, or proteopathic seeds, may drive the progression of neurodegenerative diseases in a prion-like manner. In tauopathies such as Alzheimer's disease, this model predicts that tau seeds propagate pathology through the brain via cell-cell transfer in neural networks. The critical role of tau seeding activity is untested, however. It is unknown whether...
متن کاملRhodanine-based tau aggregation inhibitors in cell models of tauopathy.
The two histopathological hallmarks that characterize Alzheimer s disease (AD) are the extracellular amyloid plaques that are formed by b-amyloid fragments of the amyloid precursor protein (APP), and intracellular neurofibrillary tangles and neuropil threads, which consist of the microtubule-associated protein tau forming paired helical filaments with highly ordered structures, as recently corr...
متن کاملInhibition of tau aggregation in cell models of tauopathy.
The pathological aggregation of tau into paired helical filaments is a hallmark of several neurodegenerative diseases, including Alzheimer's disease. We have generated cell models of tau aggregation in order to study mechanisms involving abnormal changes of tau. In the cell models the repeat domain of tau (tau(RD)) and some of its variants are expressed in a regulated fashion, e.g. the 4-repeat...
متن کاملIn Vivo Tau Imaging for a Diagnostic Platform of Tauopathy Using the rTg4510 Mouse Line
Association of tau deposition with neurodegeneration in Alzheimer's disease (AD) and related tau-positive neurological disorders collectively referred to as tauopathies indicates contribution of tau aggregates to neurotoxicity. The discovery of tau gene mutations in FTDP-17-tau kindreds has provided unequivocal evidence that tau abnormalities alone can induce neurodegenerative disorders. Theref...
