Figure 7. Effects of AAVs on pain assessment after LDD. Von Frey filament test was applied to evaluate the mechanical and thermal pain in 4 consecutive days. (A) Measurement of mechanically induced withdrawal threshold. (B) Measurement of thermally induced withdrawal latency of the paw. *(in yellow) p<0.05: shDNMT1+shTGFβ1 vs scramble. NS: non-significant. N=7.
