abstract = {In developing vertebrate neurons, a neurite is formed by
more than a hundred microtubules. While individual
microtubules are dynamic, the microtubule array has been
regarded as stationary. Using live-cell imaging of neurons
in culture or in brain slices, combined with photoconversion
techniques and pharmacological manipulations, we uncovered
that the microtubule array flows retrogradely within
neurites to the soma. This flow drives cycles of microtubule
density, a hallmark of the fluctuating state before axon
formation, thereby inhibiting neurite growth. The motor
protein dynein fuels this process. Shortly after axon
formation, microtubule retrograde flow slows down in the
axon, reducing microtubule density cycles and enabling axon
extension. Thus, keeping neurites short is an active
process. Microtubule retrograde flow is a novel type of
cytoskeletal dynamics, which changes the hitherto
axon-centric view of neuronal polarization.},
