概要 Within the set of fluoro-gold-labeled neurons, 10% were positive for GAP43 in sham-operated animals, 22% positive in the TNF-deficient NP group, and 38% positive in the wild-type NP group. These intergroup differences in the percentage of GAP43-positive neurons were statistically significant (sham vs. TNF-deficient NP group: P = 0.009; TNF-deficient NP group vs wild-type NP group: P = 0.026). CONCLUSION.: The percentage of fluoro-gold-labeled GAP43-immunoreactive neurons significantly increased after injections of NP harvested from both mouse types. Furthermore, the percentage of GAP43-immunoreactive neurons was significantly higher in mice receiving wild-type NP compared with mice receiving TNF-deficient NP. These findings suggest that TNF-alpha acts as an inducer of axonal growth into degenerated discs, as evidenced by decreased GAP-43 immunoreactivity in mice receiving TNF-deficient NP injections and even lower GAP-43 immunoreactivity in control mice receiving NP-free fluoro-gold injections.
