Intracellular visualization of tetrodotoxin (TTX) in the skin of a puffer Tetraodon nigroviridis by immunoenzymatic technique

Toxicon, 2003
Micro-distributions of tetrodotoxin (TTX) in the skin of a brackish-water puffer Tetraodon nigroviridis were investigated by means of a monoclonal anti-TTX antibody under light and transmission electron microscope. In light microscopy TTX antigen was visualized as brown color in undifferentiated basal cells and succiform cells of the skin, while in ...

Detection of tetrodotoxin (TTX) from two copepods infecting the grass puffer Takifugu niphobles: TTX attracting the parasites?

Toxicon, 2006
In May 2002, two parasitic copepods, Pseudocaligus fugu and Taeniacanthus sp., were collected from the body surface and gill of the grass puffer Takifugu niphobles, respectively, in Takehara city, Hiroshima Prefecture, faced with Seto Inland Sea located in the western part of Japan.

Use-Dependent Block by Lidocaine but Not Amitriptyline Is More Pronounced in Tetrodotoxin (TTX)-Resistant Nav1.8 Than in TTX-Sensitive Na+ Channels

The Journal of Pharmacology and Experimental Therapeutics, 2007
The excitability of sensory neurons depends on the expression of various voltage-gated Na+ channel isoforms. The tetrodotoxin-resistant (TTXr) Na+ channel Na(v)1.8 accounts for the electroresponsiveness of nociceptive neurons and contributes to inflammatory and neuropathic pain.

Mechanism of Action of Tetrodotoxin (TTX) and Saxitoxin (STX)

1971
Marine toxins such as TTX and STX have aroused the interest of physiologists, biochemists, pharmacologists, and biological warfare people, as well as writers of spy and mystery stories. In the hands of the neuroscientist they have been turned into helpful instruments vital for the study of nerve function and excitable membranes.

Effect of tetrodotoxin (TTX) on some brain neurotransmitters in rats.

Journal of natural toxins, 2002
Tetrodotoxin (TTX) is a potent marine neurotoxin named after the order of fish from which it is most commonly associated, the Tetraodontiforms, or the tetraodon pufferfish. In the present study the crude TTX was extracted from pufferfish Lagocephalus sceleratus collected from the Red Sea in Egypt.

Asymmetric Fos labeling in lobule X of the cerebellum following transtympanic tetrodotoxin (TTX) in the rat

Neuroscience Letters, 2003
Unilateral transtympanic administration of the sodium channel blocker tetrodotoxin (75 microl of 3 mM TTX in 0.1 M citrate buffer, pH 5.0) produced behavioral symptoms indicative of unilateral vestibular disruption. Following survival times of 2 and 24 h immunocytochemistry for Fos revealed asymmetric labeling in the granular and molecular layers of ...
