Effect of reduction of GRK2 in GFAP-positive astrocytes on carrageenan- and CCL3-induced hyperalgesia. a, GRK2 protein levels in microglia (n = 4) and astrocytes (n = 4) of GFAP-GRK2f/+ and control GFAP-GRK2+/+ mice. The inset depicts Western blots for GRK2 protein and β-actin as a loading control. b, Percentage decrease in heat withdrawal latency after intraplantar carrageenan injection in GFAP-GRK2+/+ (n = 8) and GFAP-GRK2f/+ mice (n = 8). c, Percentage decrease in heat withdrawal latency after intraplantar CCL3 injection in GFAP-GRK2+/+ (n = 16) and GFAP-GRK2f/+ (n = 16). Data are expressed as mean ± SEM.
