Alzheimer’s disease (AD) and progressive supranuclear palsy (PSP) are incurable neurodegenerative disorders that share some common pathological hallmarks, such as synapse loss and the presence of intraneuronal neurofibrillary tangles (NFTs) composed of hyperphosphorylated microtubule-associated protein tau (MAPT or TAU) [1, 2]. This evidence concerns the gene MAPT and progressive supranuclear palsy.
