Fig 1: Effect of BoNT/A on growth associated protein 43 (GAP43) expression. (A) Image depicting immunofluorescence staining (scale bar = 150 µm; 200× magnification). (B) The ELISA results indicate significantly higher expression of GAP43 in the IT and DT groups compared with that in the control group at all time points, with a significant difference being observed between the IT and DT groups at week 3. * indicates IT group vs. control group, ∆ indicates IT group vs. DT group, and # indicates DT group vs. control group (p < 0.05). n = 5 in each group. The error bars indicate the standard error of the mean.
