Guidance Receptors Find Their Places in the Axonal Order

Abstract

In this issue of Neuron, Katsuki and colleagues show that cell-autonomous mechanisms divide Drosophila axons into proximal and distal compartments. Axon guidance receptors selectively localize to one compartment. A diffusion barrier exists near the compartment boundary, suggesting that it may have properties like those of the axon initial segment in mammalian neurons.
