VAMP1 reappearance following β-Btx injection at BoNT/B-poisoned NMJs. β-Btx was administered i.m. in mice hind limbs 24 h after BoNT/B injection. Soleus muscles were then processed for immunohistochemistry after electrophysiological recordings. Similarly to α-Ltx, regeneration of nerve terminals takes place by day four and is paralleled by the re-appearance of VAMP1 staining at NMJs. Bar = 10 µm.
