No change in p-Src family expression in primary sensory neurons after L5 SNL. A–C, p-Src family immunostaining in the naive DRG (A) and the ipsilateral L4 (B) and L5 (C) DRG at day 7 after nerve injury. D, Western blot analysis indicates no difference in p-Src family level between the naive DRG and the ipsilateral L4/5 DRG at day 7. E–H, Dark-field photomicrographs of ISHH showing expression of TRPV1 and TRPA1 mRNA in the ipsilateral L4 DRG in the vehicle (E, G) and PP2 (F, H) groups at day 7 after nerve injury. I, J, Quantification of the percentage of TRPV1 (I) and TRPA1 (J) mRNA-positive neurons at day 7. Data represent mean ± SD; n = 4 per group. *p < 0.05 compared with the naive control. Scale bar, 100 μm.
