Colocalization and fluorescence resonance energy transfer between cdk5 and AT8 suggests a close association in pre-neurofibrillary tangles and neurofibrillary tangles.

Cyclin-dependent kinase 5 (cdk5) is a serine/threonine kinase that, when activated, induces neurite outgrowth. Recent in vitro studies have shown that cdk5 phosphorylates tau at serine 199, serine 202, and threonine 205 and that p25, an activator of cdk5, is increased in Alzheimer disease (AD). Since tau is hyperphosphorylated at these sites in neurofibrillary tangles, we examined brain tissue ...

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...

Microtubule-affinity regulating kinase (MARK) is tightly associated with neurofibrillary tangles in Alzheimer brain: a fluorescence resonance energy transfer study.

Paired helical filaments, the main structural components of the neurofibrillary tangles in Alzheimer disease, consist of phosphorylated tau protein. Because the levels and degree of phosphorylation are significantly higher in paired helical filament (PHF)-derived tau than in normal adult tau, and because phosphorylation of tau severely disrupts microtubule stability, it is postulated that tau p...

Is there a spatial association between senile plaques and neurofibrillary tangles in Alzheimer's disease?

OBJECTIVE To test the hypothesis that the clusters of senile plaques (SP) and neurofibrillary tangles (NFT) in patients with Alzheimer's disease (AD) are spatially associated as predicted by the 'Amyloid Cascade Hypothesis'. METHODS The spatial association between the SP and NFT was studied in the cerebral cortex and hippocampus in six cases of sporadic Alzheimer's disease (AD) using continge...

Senile plaques and neurofibrillary tangles in cortical neurons in AD

Neurodegenerative disorders are characterized clinically by insidious onset and slowly progressive course, and are frequently hereditary. Pathologically, these diseases share a common feature: the selective loss of a particular subset of neurons for unknown reasons [e.g. cerebral cortical neurons in ALZHEIMER’S DISEASE (AD) (see Glossary), substantia nigra neurons in PARKINSON’S DISEASE (PD), s...
