(A) Path is required for dendrite growth in somatosensory neurons. Representative images are shown for somatosensory neuron dendrite arbors in wild type and  path  mutant larvae. (B) Putative pathway for Path-mediated growth control. Path regulates translational capacity in neurons via an unknown pathway that might involve TORC1. (C) Path control of translational capacity. Even in the absence of path function, cells have residual translation capacity that is sufficient to support growth of most cell types under laboratory conditions. A prediction of this model is that stresses that compromise translation efficiency should sensitize cells to a requirement for path function.
