The distribution of FG labeled neurons and expression of ATF3 in the TG in naïve, sham-operated, and IAMNT mice. FG-labeled neurons were mainly distributed in the mandibular division (3rd) of TG in naïve mice (A-C) and decreased after IAMNT (B,F). The ATF3 expression was increased after IAMNT (B,D,G). No obvious colocalization of FG and ATF3 were found (E,H). *** P < 0.001 (vs naïve). Scale bars, 500 μm in A, 100 μm in C–H. n = 3 for each group.
