HDAC6 and Miro1: Another interaction causing trouble in neurons

Abstract

Van Den Bosch highlights the discovery by Kalinski et al. of Miro1 as an HDAC6 substrate that regulates mitochondrial trafficking in neurons and axon regeneration.

Abstract

Myelin-associated glycoprotein and chondroitin sulfate proteoglycans in the extracellular matrix can prevent regeneration of injured axons. In this issue, Kalinski et al. (2019. J. Cell Biol. https://doi.org/10.1083/jcb.201702187) report that inhibition of HDAC6 prevents the deacetylation of Miro1, increases mitochondrial axonal transport, and restores the size of axonal growth cones.
