Abstract
Botulinum neurotoxins (BoNTs) are a growing family of bacterial protein toxins that cause a generalized flaccid paralysis of botulism by inactivating neurotransmitter release at peripheral nerve terminals. They are the most potent toxins known thanks to the marvel of their protein design, which underlines their mechanism of action. Their unique biological properties have led them to become also highly effective and successful therapeutic agents for the treatment of a variety of human syndromes. This chapter reports the progress on our understanding of BoNTs, highlighting the different steps of their molecular mechanism of action as key aspects to explain their extreme toxicity but also their unique pharmacological properties.
