Tau pathophysiology in neurodegeneration: a tangled issue

WebNeurodegenerative tauopathies are marked by their common pathologic feature of aggregates formed of hyperphosphorylated tau protein, which are associated with synapse and neuronal loss. Changes in tau conformation result in both loss of normal function and gain of fibrillogenicity that leads to aggregation. Here, we discuss the pathophysiology of … Tauopathy belongs to a class of neurodegenerative diseases involving the aggregation of tau protein into neurofibrillary or gliofibrillary tangles in the human brain. Tangles are formed by hyperphosphorylation of the microtubule protein known as tau, causing the protein to dissociate from microtubules and form insoluble aggregates.
