IVIg reduce the loss of innervation induced by BTZ. BTZ induced an evident reduction in the IENF density, which partially recovered at the end of co-treatment in the preventive group. Until week 3 from the beginning of the study, rats eventually belonging to the therapeutic schedule group are reported together with the animals of the BTZ group. Data are reported as mean ± SEM. *p < 0.01 vs BTZ; **p < 0.05 vs BTZ
