Transcellular Spreading of Tau in Tauopathies.

ABSTRACT: Tau, a microtubule-associated protein playing a key role in a group of neurodegenerative diseases such as Alzheimer's disease, spreads throughout the brain, inducing pathology. A model akin to the spreading of prions has been raised owing to similar characteristics of inducing an abnormal protein conformation as a method of self-amplification, spreading protein aggregates over anatomically linked pathways. The search to identify the "seeds" that induce conformational change has received much attention; however, less is known about the mechanisms by which tau is transmitted from cell to cell, so-called "transcellular spreading". In this review, we gather evidence regarding the spreading of tau throughout the brain and provide an overview of methods by which tau can be released from neurons
