Figure 4From: Effective relief of neuropathic pain by adeno-associated virus-mediated expression of a small hairpin RNA against GTP cyclohydrolase 1 Mechanical pain development following pain injury. Spared nerve injury was operated by tightly ligating and transectioning the tibial and common peroneal nerves and leaving sural nerves intact. As shown here, the animals promptlly developed pain behavior that was determined by mechanical von Fray threshold.Back to article page
