Silencing of CDK5 reduces neurofibrillary tangles in transgenic alzheimer's mice.
Alzheimer's disease is a major cause of dementia for which treatments remain unsatisfactory. Cyclin-dependent kinase 5 (CDK5) is a relevant kinase that has been hypothesized to contribute to the tau pathology. Several classes of chemical inhibitors for CDK5 have been developed, but they generally lack the specificity to distinguish among various ATP-dependent kinases. Therefore, the efficacy of...
متن کاملAccelerated amyloid deposition, neurofibrillary degeneration and neuronal loss in double mutant APP/tau transgenic mice.
Even though the idea that amyloid beta peptide accumulation is the primary event in the pathogenesis of Alzheimer's disease has become the leading hypothesis, the causal link between aberrant amyloid precursor protein processing and tau alterations in this type of dementia remains controversial. We further investigated the role of beta-amyloid production/deposition in tau pathology and neuronal...
متن کاملReversal of neurofibrillary tangles and tau-associated phenotype in the rTgTauEC model of early Alzheimer's disease.
Neurofibrillary tangles (NFTs), a marker of neuronal alterations in Alzheimer's disease (AD) and other tauopathies, are comprised of aggregates of hyperphosphorylated tau protein. We recently studied the formation of NFTs in the entorhinal cortex (EC) and their subsequent propagation through neural circuits in the rTgTauEC mouse model (de Calignon et al., 2012). We now examine the consequences ...
متن کاملTau-Targeted Immunization Impedes Progression of Neurofibrillary Histopathology in Aged P301L Tau Transgenic Mice
In Alzheimer's disease (AD) brains, the microtubule-associated protein tau and amyloid-β (Aβ) deposit as intracellular neurofibrillary tangles (NFTs) and extracellular plaques, respectively. Tau deposits are furthermore found in a significant number of frontotemporal dementia cases. These diseases are characterized by progressive neurodegeneration, the loss of intellectual capabilities and beha...
متن کاملFirst transgenic rat model developing progressive cortical neurofibrillary tangles.
Neurofibrillary degeneration induced by misfolded protein tau is considered to be one of the key pathological hallmarks of Alzheimer's disease (AD). In the present study, we have introduced a novel transgenic rat model expressing a human truncated tau that encompasses 3 microtubule binding domains (3R) and a proline-rich region (3R tau151-391). The transgenic rats developed progressive age-depe...
