BDNF expression and channel/cotransport composition were assessed for the control, CPSP, and P2X7/CPSP groups. (A) BDNF expression (pg/mL) was measured for the control, CPSP, and P2X7/CPSP groups (n = 8 per group). (B) TrkB receptors, (D) KCC2 cotransport, (F) NKCC1 cotransport, and (H) GABAa receptor were measured in the medial thalamus for the control, CPSP, and P2X7/CPSP groups (n = 6–7 per group). Western blotting approaches showed specific proteins, such as (C) TrkB receptors, (E) KCC2, (G) NKCC1, and (I) GABAa receptors. P2X7/CPSP: P2X7 receptor knock-out mice that induced the CPSP symptoms. n.s.: nonsignificant differences. * p < 0.05 indicates significant differences.
