Expression levels of GABAA, A1R, TRPV1, TRPV4, and mGluR3 receptors in rat SSC. (a) GABAA, (b) A1R, (c) TRPV1, (d) TRPV4, and (e) mGluR3 expression levels in the SSC of rats from the sham, 2-Hz EA, and 15-Hz EA groups (from left to right). Sham: neuropathic pain rats with sham EA; 2 Hz: neuropathic pain rats that received 2-Hz EA; 15 Hz: neuropathic pain rats that received 15-Hz EA. p < 0.05 compared with the sham group. The Western blot bands at the top of each panel show the target protein. The lower bands are internal controls (β-actin). A1R: adenosine A1 receptor; DRG: dorsal root ganglion; EA: electroacupuncture; GABA: γ-aminobutyric acid; TRPV1: transient receptor potential cation channel subfamily V member 1; mGluR3: metabotropic glutamate receptor 3; TRPV4: transient receptor potential cation channel subfamily V member 4.
