abstract = {An inhibitory extracellular milieu and neuron-intrinsic
processes prevent axons from regenerating in the adult
central nervous system (CNS). Here we show how the two
aspects are interwoven. Genetic loss-of-function experiments
determine that the small GTPase RhoA relays extracellular
inhibitory signals to the cytoskeleton by adapting
mechanisms set in place during neuronal polarization. In
response to extracellular inhibitors, neuronal RhoA
restricts axon regeneration by activating myosin II to
compact actin and, thereby, restrain microtubule protrusion.
However, astrocytic RhoA restricts injury-induced
astrogliosis through myosin II independent of microtubules
by activating Yes-activated protein (YAP) signaling.
Cell-type-specific deletion in spinal-cord-injured mice
shows that neuronal RhoA activation prevents axon
regeneration, whereas astrocytic RhoA is beneficial for
regenerating axons. These data demonstrate how extracellular
inhibitors regulate axon regeneration, shed light on the
capacity of reactive astrocytes to be growth inhibitory
after CNS injury, and reveal cell-specific RhoA targeting as
a promising therapeutic avenue.},
