text: The issue of whether neuron loss occurs, and if so, in what 
  subpopulations, is important. It will likely have implications for our 
  understanding of reinnervation and functional recovery in patients. 
  Furthermore, better insight will provide critical context for those 
  investigating the plasticity that occurs following nerve injury and 
  may inform therapeutic targeting of sensory neuron populations. 
  
  An expanding repertoire of transgenic recombinase driver lines 
  now makes it possible to permanently label DRG neuron 
  subpopulations and study their fate in rodent nerve injury paradigms. 
  The aim of this study was to use this technology to characterize
