Impaired retrograde transport by the Dynein/Dynactin complex contributes to Tau-induced toxicity.
The gene mapt codes for the microtubule-associated protein Tau. The R406W amino acid substitution in Tau is associated with frontotemporal dementia with parkinsonism linked to chromosome 17 (FTDP-17) characterized by Tau-positive filamentous inclusions. These filamentous Tau inclusions are present in a group of neurodegenerative diseases known as tauopathies, including Alzheimer's disease (AD)....
متن کاملTau phosphorylation affects its axonal transport and degradation
Phosphorylated forms of microtubule-associated protein tau accumulate in neurofibrillary tangles in Alzheimer's disease. To investigate the effects of specific phosphorylated tau residues on its function, wild type or phosphomutant tau was expressed in cells. Elevated tau phosphorylation decreased its microtubule binding and bundling, and increased the number of motile tau particles, without af...
متن کاملMitotic-like tau phosphorylation by p25-Cdk5 kinase complex.
Among tau phosphorylation sites, some phosphoepitopes referred to as abnormal ones are exclusively found on tau aggregated into filaments in Alzheimer's disease. Recent data suggested that molecular mechanisms similar to those encountered during mitosis may play a role in abnormal tau phosphorylation. In particular, TG-3 phosphoepitope is associated with early stages of neurofibrillary tangles ...
متن کاملPseudophosphorylation of tau at S422 enhances SDS-stable dimer formation and impairs both anterograde and retrograde fast axonal transport
In Alzheimer's disease (AD), tau undergoes numerous modifications, including increased phosphorylation at serine-422 (pS422). In the human brain, pS422 tau protein is found in prodromal AD, correlates well with cognitive decline and neuropil thread pathology, and appears associated with increased oligomer formation and exposure of the N-terminal phosphatase-activating domain (PAD). However, whe...
متن کاملLocating corticospinal neurons by retrograde axonal transport of horseradish peroxidase.
Different views of the location and organization of corticospinal (CS) neurons in the rat have resulted from fiber degeneration studies, electrophysiologically derived somatotopic maps, studies of CS axonal branching, and functional alterations af’ter ablation of parts of the motor-sensory cortex. To locate more precisely CS neurons that projected to different levels of the spinal cord, and to ...
