Investigating Diet as the Source of Tetrodotoxin in Pleurobranchaea maculata

open access: yesMarine Drugs, 2013
The origin of tetrodotoxin (TTX) is highly debated; researchers have postulated either an endogenous or exogenous source with the host accumulating TTX symbiotically or via food chain transmission.

Intracellular Immunohistochemical Detection of Tetrodotoxin in Pleurobranchaea maculata (Gastropoda) and Stylochoplana sp. (Turbellaria) [PDF]

open access: yesMarine Drugs, 2015
Tetrodotoxin (TTX), is a potent neurotoxin targeting sodium channels that has been identified in multiple marine and terrestrial organisms. It was recently detected in the Opisthobranch Pleurobranchaea maculata and a Platyhelminthes Stylochoplana sp ...

Diversity and Biosynthetic Potential of Culturable Microbes Associated with Toxic Marine Animals

open access: yesMarine Drugs, 2013
Tetrodotoxin (TTX) is a neurotoxin that has been reported from taxonomically diverse organisms across 14 different phyla. The biogenic origin of tetrodotoxin is still disputed, however, TTX biosynthesis by host-associated bacteria has been reported.

An Updated Review of Tetrodotoxin and Its Peculiarities

open access: yesMarine Drugs, 2022
Tetrodotoxin (TTX) is a crystalline, weakly basic, colorless organic substance and is one of the most potent marine toxins known. Although TTX was first isolated from pufferfish, it has been found in numerous other marine organisms and a few terrestrial ...

The Microbial Community of Tetrodotoxin-Bearing and Non-Tetrodotoxin-Bearing Ribbon Worms (Nemertea) from the Sea of Japan

open access: yesMarine Drugs, 2020
A potent marine toxin, tetrodotoxin (TTX), found in a great variety of marine and some terrestrial species, leaves intriguing questions about its origin and distribution in marine ecosystems. TTX-producing bacteria were found in the cultivable microflora

Accumulation and Elimination of Tetrodotoxin in the Pufferfish Takifugu obscurus by Dietary Administration of the Wild Toxic Gastropod Nassarius semiplicata

open access: yesToxins, 2020
To investigate pufferfish accumulation, elimination, and distribution of tetrodotoxin (TTX), Takifugu obscurus was fed with wild TTX-containing gastropod Nassarius semiplicata to simulate the natural food chain. Three-month-old non-poisonous T.

TTX-S/TTX-R Na<sup>+</sup> Currents Coordinately Fine-Tune Depolarization/Firing Capability Revealed by Voltage Derivatives/Displacement Current Phase Plots With Dynamic Current-Clamp Simulation in Rat Visceral Sensory Neurons. [PDF]

open access: yesActa Physiol (Oxf)
ABSTRACT Aim To investigate how tetrodotoxin‐sensitive (TTX‐S) and tetrodotoxin‐resistant (TTX‐R) Na+ channels coordinately fine‐tune action potential (AP) depolarization and firing capability in rat nodose visceral sensory neurons. Methods APs were recorded by ruptured‐patch current clamp in unmyelinated C‐type and myelinated Ah‐type neurons from ...

Tetrodotoxin Profiles in Xanthid Crab Atergatis floridus and Blue-Lined Octopus Hapalochlaena cf. fasciata from the Same Site in Nagasaki, Japan

open access: yesToxins, 2023
The xanhid crab Atergatis floridus and the blue-lined octopus Hapalochlaena cf. fasciata have long been known as TTX-bearing organisms. It has been speculated that the TTX possessed by both organisms is exogenously toxic through the food chain, since ...

Characterization of persistent TTX-R Na+ currents in physiological concentration of sodium in rat visceral afferents

open access: yesInternational Journal of Biological Sciences, 2009
Persistent tetrodotoxin-resistant (TTX-R) Na+ (Nav1.9/SCN11A) currents are not normally recorded in vagal afferent neurons (VANs) with 50 mM of extracellular Na+ although the functional expression of this current was observed in the presence of PGE2 or ...
