Expression of genes regulated by IFN-γ or IFN-α after partial sciatic nerve ligation (PNL) was upregulated. A, The increase in expression level of IFN-γ-regulated genes was more intensive in CB2
−/− than in CB2
+/+ mice, whereas the upregulation in IFN-α-regulated genes was less intensive in CB2
−/− animals. B, Taqman real-time PCR analysis of the expression of three GTPase regulated genes also showed a stronger expression change in CB2
−/− than in CB2
+/+ mice after neuropathy. wt-i, Ipsilateral paw of CB2
+/+ mice; wt-c, contralateral paw of CB2
+/+ mice; ko-i, ipsilateral paw of CB2
−/− mice; ko-c, contralateral paw of CB2
−/− mice.
