Blue-ringed octopuses carry a killer concoction called tetrodotoxin (TTX), a potent neurotoxin that can paralyze living things, including humans. Tetrodotoxin is most famously known from pufferfish — ...

Data=Ministry of Food and Drug Safety People who cooked and ate pufferfish themselves and showed symptoms of food poisoning caused by pufferfish poison were transferred to the hospital. According to ...

Tetrodotoxin is a neurotoxin that can be fatal to humans with just a two-milligram dose. “It's one of those things where a drop can kill 100 people,” Gabriel Somarriba, ...

Tetrodotoxin is a neurotoxin, meaning it takes out the nervous system as it moves through the body. This may sound like a relatively painless death, with the brain going offline quickly.

Tetrodotoxin is used often in neuroscience labs to study how pain works at a cellular level. “It’s virtually an irreplaceable tool,” says Alasdair Gibb at University College London.

Tetrodotoxin has a unique, highly complex, cage-like structure (a tricyclic orthoester) as well as a cyclic guanidine component. Guanidine is an important component of many biological molecules, ...

Many damage-sensing neurons express tetrodotoxin (TTX)-resistant voltage-gated sodium channels. Here we examined the role of the sensory-neuron-specific (SNS) TTX-resistant sodium channel α ...

Tetrodotoxin poisoning can also cause death, usually as a result of respiratory paralysis, according to court documents. The substance is usually reserved for use in research settings.

Tetrodotoxin simply doesn’t make sense as a drug (and let’s be honest — if it did, humans would be snorting it off bathroom counters already). In very, very, very low doses, ...

Hammerhead tetrodotoxin, which disrupts neurons’ signaling to muscles, can sicken pets if they eat the worms, according to the New Jersey Department of Environmental Protection.
