Molecular structure reveals how botulinum toxin attaches to nerve cells May lead to new therapeutics Botulism is a life-threatening disease caused by exposure to botulinum neurotoxins, which are among the most potent toxins known. These neurotoxins are produced by Clostridium botulinum, a bacterium found in soil and food. In the body, the toxins bind to and enter neurons, interfering with nerve transmission and disrupting the communication between the nerve and muscle fibers throughout the body. Poisoning with botulinum toxins leads to an often-fatal paralysis, which is one reason they are considered among the highest biodefense research priorities by the U.S. government.
