The Actions and Mechanisms of P2X7R and p38 MAPK Activation in Mediating Bortezomib-Induced Neuropathic Pain

Figure 1

Mechanical threshold and P2X7R and p-p38 expression. (a) Mechanical threshold after BTZ injection. (b, c) Western blot for P2X7R expression after BTZ treatment. (d) Immunofluorescence location of P2X7R in DRG. The arrows indicate the typical single- or double-labeled DRG neurons and satellite cells. P2X7R is not expressed in NF-200-positive neurons. P2X7R is expressed in GFAP-labeled satellite glial cells (SGCs). (e) Immunofluorescence location of p-p38 in DRG. The arrows indicate the typical single- or double-labeled DRG neurons and satellite cells. p-p38 is expressed in both MAP2-labeled neurons and GFAP-labeled SGCs. (f) Immunofluorescence location of P2X7R in SDH. The arrows indicate the typical single-labeled and double-labeled cells in SDH. P2X7R is expressed mainly in Iba-1-labeled microglial cells rather than in GFAP-labeled astrocytes and MAP2-labeled neurons. (g) Immunofluorescence location of p-p38 in SDH. The arrows indicate the typical single-labeled and double-labeled cells in SDH. p-p38 is expressed mainly in Iba-1-labeled microglial cells. . (). ; ; .
