Abstract

Cell Biology Life Sciences & Biomedicine Science & Technology
Tau is a multifunctional microtubule-associated protein in the neuron. For decades, tau's main function in neurons has been broadly accepted as stabilizing microtubules in the axon; however, this conclusion was reached mainly on the basis of studies performed in vitro and on ectopic expression of tau in non-neuronal cells. The idea has become so prevailing that some disease researchers are even seeking to use microtubule-stabilizing drugs to treat diseases in which tau dissociates from microtubules. Recent work suggests that tau is not a stabilizer of microtubules in the axon, but rather enables axonal microtubules to have long labile domains, in part by outcompeting genuine stabilizers. This new perspective on tau challenges long-standing dogma.
