Difference between expression of BDNF and trkB in TRG neurons in naïve and inflamed rats. A-D : Naïve rats. FG/MB-labeled TRG neurons innervating MM ( A ) and projecting to Vi/Vc ( B ). Triangle shows an example of FG/MB-labeled and BDNF/trkB-IR TRG neurons. E-H : Inflamed rats. FG/MB-labeled TRG neurons innervating MM (C,D) ( E ) and projecting to Vi/Vc ( F ). Triangle shows an example of FG/MB-labeled and BDNF/trkB-IR TRG neurons. Bar = 20 μm. I : Size frequency distribution of FG/MB-labeled BDNF-IR TRG neurons in naïve and inflamed rats (G,H). K: Comparison of FG/MB-labeled BDNF-IR TRG neurons per section in both naïve and inflamed rats. *P < 0.05. J : Size frequency distribution of FG/MB-labeled trkB-IR TRG neurons in naïve and inflamed rats. L: Comparison of FG/MB-labeled trkB-IR TRG neurons per section in both naïve and inflamed rats.*P < 0.05.
