WebTau is the major microtubule associated protein (MAP) of a normal mature neuron. The other two neuronal MAPs are MAP1 and MAP2. Tau is found as six molecular isoforms in human brain [1]. These isoforms are coded by a single gene on chromosome 17 and are generated by alternative splicing of its pre-mRNA [2]. WebIn the acute AD-like mouse model injected with amyloid beta, amyloid beta aggregation, and tau pathology, which are representative pathological markers of AD, occur .

Depending on the isoform, its molecular weight ranges from 55 kDa-62 kDa 1. Under normal circumstances, tau interacts with tubulin to stabilize microtubule assembly.

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.
