<p>A) Representative images of PirB immunostained sciatic nerve at 2, 4, and 8 weeks after lesion (wal). Undamaged nerve was used as a control (zero wal). Scale bar: 100 μm. B) PirB expression quantification by the integrated density of pixels method, where the ratio lesioned/unlesioned was employed. Data are presented as the mean ± SEM. n = 6 in each time point. *p<0.05; **p<0.01; ***p<0.001 according to the one-way ANOVA, followed by Bonferroni post-tests.</p
