Abstract |
Peripheral nerve injury remains a common clinical problem with no satisfactory treatment options. Numerous studies have shown that hepatocyte growth factor (HGF) exerts neurotrophic effect in motor, sensory, and parasympathetic neurons in addition to mitogenic, morphogenic, angiogenic, antiapoptotic, antifibrotic, and anti-inflammatory effect on various tissues and cells. In our study we examined efficacy of gene therapy with HGF-bearing plasmid (pC4W-hHGF) to improve consequences of traumatic nerve injury in mice.
Treatment by pC4W-hHGF led to restoration of nerve structure and functional recovery compared to similar parameters in control animals. Compound action potentials (CAP) in experimental groups treated with 100 or 200 μg of pC4W-hHGF demonstrated increased amplitude and latency decrease compared to spontaneous recovery control group. In HGF-treated mice histological analysis showed a three-fold increase in axon number in nerve portion located distal to the lesion site compared to control. Moreover, significant functional recovery of n. peroneus communis triggered by pC4W-hHGF gene therapy was observed using the footprints analysis. Obtained results provide evidence for plasmid-based HGF gene therapy as a potential treatment for traumatic injury of peripheral nerve.
