WebJul 22, 2024 · Tau interacts with mitochondrial proteins and impairs mitochondrial bioenergetics and dynamics . Furthermore, tau influences mitochondrial transport along the neuronal axon [51,52]. Several studies have demonstrated that the abnormal forms of tau protein accumulated in tauopathies impaired mitochondrial function. WebMar 18, 2024 · Alzheimer’s disease is the most common and best known of the tauopathies, a set of neurodegenerative brain diseases caused by toxic tangles of the protein tau.
