Toll-tally tubular: A newly identified Toll-like receptor-FoxO pathway regulates dynamics of the neuronal microtubule network

Abstract

Recent studies reveal a conserved role for FoxO transcription factors in establishing neuronal structure and circuit function. In this issue, McLaughlin et al. (2016. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201601014) identify a novel Toll-like receptor-FoxO pathway that represses the mitotic kinesin Pavarotti/MKLP1 to promote dynamic microtubules required for axonal transport and activity-dependent remodeling of presynaptic terminals.
