It was designed to produce an antibody that neutralizes tetrodotoxin, a deadly neurotoxin produced by pufferfish and other marine animals. After colonizing an animal host with the modified hookworms, the parasites produced the antitoxin and secreted it into the bloodstream, partially inactivating the toxin.
