Seasonal Changes in the Tetrodotoxin Content of the Flatworm Planocera multitentaculata

open access: yesMarine Drugs, 2017
Tetrodotoxin (TTX) is a potent neurotoxin that acts specifically on voltage-gated sodium channels on excitable membranes of muscle and nerve tissues. The biosynthetic process for TTX is unclear, although marine bacteria are generally thought to be the ...

Toxic Flatworm Egg Plates Serve as a Possible Source of Tetrodotoxin for Pufferfish

open access: yesToxins, 2019
The pufferfish Takifugu niphobles (at present Takifugu alboplumbeus) possesses highly concentrated tetrodotoxin (TTX), an extremely potent neurotoxin that provides effective protection from predators, at least at the larval stages. However, the source of

The Zoonotic Helminth Parasite Fasciola hepatica: Virulence-Associated Cathepsin B and Cathepsin L Cysteine Peptidases Secreted by Infective Newly Excysted Juveniles (NEJ)

open access: yesAnimals, 2021
Fasciolosis caused by Fasciola hepatica is a major global disease of livestock and an important neglected helminthiasis of humans. Infection arises when encysted metacercariae are ingested by the mammalian host. Within the intestine, the parasite excysts

First Detection of Tetrodotoxins in the Cotylean Flatworm Prosthiostomum trilineatum

open access: yesMarine Drugs, 2021
Several polyclad flatworm species are known to contain high levels of tetrodotoxin (TTX), but currently TTX-bearing flatworms seem to be restricted to specific Planocera lineages belonging to the suborder Acotylea.
