Abstract

We used the knockout mice lacking gangliosides and evaluated their response to tetanus and botulinum toxins. We found that tetanus toxin and botulinum type A or B toxin was less toxic in the knockout mice. We conclude that the toxins bind to the gangliosides on the synapses in the initial step of intoxication prior to penetration of the toxins into the neural cells.
