K252a (10–100 nm) prevents NGF (10 ng/ml) enhancement of ACh release during a short-term exposure. Data are expressed as a percentage of release in the absence of NGF and K252a (mean ± SEM; n = 6–8). Statistical analysis was performed using a two-way ANOVA with Tukey's post-test (*p < 0.001 vs K252a only, at the same concentration; ^†p = 0.0627 vs cultures receiving neither K252a nor NGF).
