Neuronal Cytoskeleton: Presynaptic Boutons as Hotspots for Activity-Dependent Microtubule Nucleation

Summary Local microtubule remodeling plays a crucial role in controlling the transport of neuronal cargo. A new study reveals that excitatory en passant boutons in the axon are hotspots for activity-induced microtubule nucleation and provide tracks for interbouton vesicle trafficking.
