text: 3.3. Spared nerve injury induces a loss of Trpm81 and 
  calcitonin gene-related peptide1 but not myelinated dorsal 
  root ganglion neurons 
  
  loss of Trpm81 (cold- 
  induced loss. To investigate potential 
  sensitive), calcitonin gene-related peptide1 (CGRP) (peptider- 
  gic), and myelinated subpopulations of DRG neurons following 
  nerve injury, we applied our FB-labelling approach in Trpm8FlpO; 
  RC::FLTG (FlpO-dependent tdTom expression), CalcaCreERT2; 
  Ai32 (Cre-dependent ChR2-YFP expression) and Thy1-CFP 
  mice, respectively (Figs. 4A–D). Trpm8-tdTom was expressed  Loss restricted to nonpeptidergic nociceptors would not fully 
  account for the degree of total neuron loss that we observed. 
  Therefore, we studied a range of other subpopulations, both 
  small and large in diameter, for their vulnerability to injury-
