Confirmation and distribution of tetrodotoxin for the first time in terrestrial invertebrates: two terrestrial flatworm species (Bipalium adventitium and Bipalium kewense). [PDF]
PLoS ONE, 2014 The potent neurotoxin tetrodotoxin (TTX) is known from a diverse array of taxa, but is unknown in terrestrial invertebrates. Tetrodotoxin is a low molecular weight compound that acts by blocking voltage-gated sodium channels, inducing paralysis. However,

A Progress on the Application of Tetrodotoxin [PDF]
E3S Web of Conferences, 2021 Tetrodotoxin (TTX), a blocker of sodium channels, exists in the pufferfish, amphibians, and octopus, and originated in endosymbiont-vibrio. Researches have confirmed that TTX affected the action potential through the regulation of voltage-gated sodium ...

Paralytic shellfish toxins (PSTs) and tetrodotoxin (TTX) of Korean pufferfish
Fisheries and Aquatic Sciences, 2021 Paralytic shellfish toxins (PSTs) and tetrodotoxin (TTX) are neurotoxins that display pharmacological activity that is similar to that of specific sodium channel blockers; they are the principle toxins involved in shellfish and puffer fish poisoning. In Korea, puffer fish is a very popular seafood, and several cases of accidental poisoning by TTX have ...
