Inhibition of Tetrodotoxin (TTX)-Resistant and TTX-Sensitive Neuronal Na+ Channels by the Secretolytic Ambroxol

Molecular Pharmacology, 2002
Ambroxol has a long history for the treatment of airway diseases because of its beneficial effects on surfactant synthesis and mucus-modifying properties. Some findings, however, point to an additional effect on neuronal signal transduction: ambroxol can suppress reflexes such as the cough or the corneal reflex.

Antinociceptive effects of tetrodotoxin (TTX) in rodents [PDF]

open access: yesBritish Journal of Anaesthesia, 2006
Tetrodotoxin (TTX) is a powerful sodium channel blocker extracted from the puffer fish. The analgesic effects of TTX were investigated in different animal pain models.Wistar rats were submitted to the formalin test and to partial ligation of the sciatic nerve (Seltzer's model). Swiss Webster mice were used in the writhing test.

Construction of a single chain variable fragment antibody (scFv) against tetrodotoxin (TTX) and its interaction with TTX

Toxicon, 2014
Tetrodotoxin (TTX) is a small molecular weight neurotoxin that occludes voltage-gated sodium channels in nerve and muscle tissue, resulting in respiratory paralysis and death. A high affinity antibody that can neutralize the toxicity of TTX is still lacking, so it is very important to prepare an antibody for TTX therapy and detection.

SERS Study of Tetrodotoxin (TTX) by Using Silver Nanoparticle Arrays

Plasmonics, 2009
The optical properties of tetrodotoxin (TTX), a scarce toxin with anesthetic properties, were studied using nanoparticle arrays-assisted surface-enhanced Raman scattering (SERS). The nanoparticles arrays were fabricated using nanosphere lithography and a metallic lift-off process to control the particle size, shape, and spacing in the arrays.

First identification of tetrodotoxin (TTX) in the flatworm Stylochoplana sp.; a source of TTX for the sea slug Pleurobranchaea maculata

Toxicon, 2015
High concentrations of the neurotoxin tetrodotoxin (TTX) were detected by liquid chromatography-mass spectrometry (LC-MS) in the Platyhelminthes Stylochoplana sp. from Pilot Bay (Tauranga, New Zealand). This is the first detection of TTX in this genus. Concentrations were monitored from March to November (2013) and found to significantly decrease from ...

Evidence of accumulation of tetrodotoxin (TTX) in tissues and body parts of ectoparasitic copepods via their feeding on mucus of TTX-bearing pufferfish

Toxicon, 2021
Adults of the ectoparasitic copepod Caligus fugu found on tetrodotoxin (TTX)-bearing pufferfish such as Takifugu alboplumbeus and Takifugu flavipterus are known to accumulate TTX in body tissues and parts other than the ovaries, oviducts, eggs, and cuticles.

THE SCENT OF DANGER: TETRODOTOXIN (TTX) AS AN OLFACTORY CUE OF PREDATION RISK

Ecological Monographs, 2006
Larvae of the California newt (Taricha torosa) exhibit striking predator-avoidance behavior, escaping to refuges in response to a chemical cue from cannibalistic adults. In laboratory flow-tank experiments, stream water collected near free-ranging adults induced hiding responses in 100% of the larvae tested.

Seafood cross-contamination by tetrodotoxin (TTX): management of an unusual route of exposure

Journal of Consumer Protection and Food Safety, 2023
In this study, liquid chromatography with tandem mass spectroscopy was applied to detect Tetrodotoxin and analogues (TTXs) on pufferfish (Sphoeroides marmoratus) tissues, accidentally found in the stomach of a cuttlefish (Sepia officinalis). The cuttlefish tissues were also analysed.
