pIONL induces the activation of ERK in the TG. a Western blot shows the expression of pERK in naive, sham, and pIONL mice. pIONL increased the expression of pERK expression in WT mice, and the increase was reduced in Cxcr5 KO mice. *P < 0.05. One-way ANOVA followed by Bonferroni test (left histogram) or Student’s t test (right histogram). b Representative images of pERK immunofluorescence in the TG of WT and KO mice 10 days after the operation. pERK-IR was increased after pIONL in WT mice, but not in KO mice
