Microglial BDNF, PI3K, and p-ERK in the Spinal Cord Are Suppressed by Pulsed Radiofrequency on Dorsal Root Ganglion to Ease SNI-Induced Neuropathic Pain in Rats

Figure 9

The intensity of Iba1, BDNF, PI3K, and p-ERK immunofluorescence in the spinal cord in different groups on D14. Each symbol represents mean ± SEM. In the BDNF assay, against the Sham group and against the SNI group. In the p-ERK assay, against the Sham group and against the SNI group. In the PI3K assay, against the Sham group and against the SNI group. In the Iba1 assay, against the Sham group and against the SNI group. LSD t test, n = 5 rats per assay.
