The MWT in the Model group reached its lowest threshold at 9 dpo, and this decrease was maintained till 13 dpo (Fig. 3A). HSVIGF1 injection induced partial recovery on the MWT inside the EA Model group (HSVIGF1 vs. HSVpNXCMV, P0.05). By contrast, MWT showed a further lower and reached its lowest threshold at 9 dpo inside the HSVsiRNAIGF1treated rats (HSVsiRNAIGF1 vs. HSVpNXU6; P0.05; Fig. 3B). No important differences were observed among the HSVpNXU6 and HSVpNXCMVinjected EA Model groups. Related alterations in TWL in every single experimental group were observed (Fig. 3C and D). These outcomes suggested that manipulating the expression of endogenous IGF1 had considerable effects on neuropathic pain following deafferentation injury.IGF1 increases CGRP and GAP43immunopositive reactions (IRs) within the EA Model group by means of the regulation of PI3KAkt. CGRPpositive fibers were observed in the lamina IV and motor neurons of spinal ventral horns inside the shamoperated and Model group (Fig. 4), respectively. CGRPIRs had been observed within the spinal cords of rats within the EA Model group (Fig. four). HSVIGF1 therapy enhanced CGRPimmunopositive staining, compared with that in the HSVpNXCMVtreated group (Fig. 4). However, HSVsiRNAIGF1 treatment was associated with decreased CGRPimmunopositive staining (HSVsiRNAIGF1 vs. HSVpNXU6; Fig. four). GAP43immunopositive staining was also enhanced within the EA Model group relative to that in theHU et al: ELECTROACUPUNCTURE PROMOTES NEUROPLASTICITY BY ACTIVATING IGF1PI3KAKTFigure four.
