Acute neurotoxicity of V. aspis is barely prevented by antivenoms. Electrophysiological recordings of EJP from mice solei (A) 48 h or (B) 7 days after the injection of V. aspis venom (100 µg/Kg) pre-incubated with Antivenom#1 or Antivenom#2 or NHS (Normal Horse Serum) (see methods). Bars represent the average EJP amplitude of 15 fibres per muscle from at least three different mice per condition, expressed as a percentage of control condition (injection of the sole vehicle); paired t‐test, *p < 0.01, **p < 0.001, ***p < 0.0001 versus control (vehicle) or #p < 0.01, ##p < 0.001, ###p < 0.0001 versus NHS; error bars represent s.e.m.; n.s. = not significant. After electrophysiology, soleus muscles were imaged for the presynaptic markers syntaxin-1A/1B (green) and for the postsynaptic ACh receptors (AChR, red) to evaluate NMJ integrity (B) 48 h or (D) 7 days. Scale bar = 10 μm.
