WebFeb 15, 2024 · INTRODUCTION. The observation of neurofibrillary tangles (NFTs) in neurons is a defining pathological feature of Alzheimer’s disease (AD). These tangles consist of paired helical filaments (PHFs) of microtubule-associated protein tau [1, 2].Such tau inclusions are also observed in other neurodegenerative diseases including Pick’s … WebTau is a family of neuronal proteins that bind to microtubules (the neuron's transport system), and stabilize their formation and maintenance. In the human brain, Tau proteins constitute a family of 6 isoforms that is produced by alternative splicing of a single gene called MAPT (Microtubule-Associated Protein Tau).
