Extracellular signal-regulated kinases mediate the enhancing effects of inflammatory mediators on resurgent currents in dorsal root ganglion neurons [PDF]

open access: yes, 2019
Previously we reported that a group of inflammatory mediators significantly enhanced resurgent currents in dorsal root ganglion neurons. To understand the underlying intracellular signaling mechanism, we investigated the effects of inhibition of ...

Determination of tetrodotoxin (TTX) levels in various tissues of the silver cheeked puffer fish (Lagocephalus sceleratus (Gmelin, 1789)) in Northern Cyprus Sea (Eastern Mediterranean).

open access: yesToxicon, 2019
Lagocephalus sceleratus from the family Tetraodontidae, which is originated from the Red Sea, started to migrate to Mediterranean waters after the opening of the Suez Channel in 1869.

Na(V)1.5 sodium channel window currents contribute to spontaneous firing in olfactory sensory neurons [PDF]

open access: yes, 2014
Olfactory sensory neurons (OSNs) fire spontaneously as well as in response to odor; both forms of firing are physiologically important. We studied voltage-gated Na+ channels in OSNs to assess their role in spontaneous activity.

Comparison of the acute inhibitory effects of Tetrodotoxin (TTX) in rat and human neuronal networks for risk assessment purposes.

open access: yesToxicology Letters, 2017
Tetrodotoxin (TTX) is an extremely toxic marine neurotoxin. TTX inhibits voltage-gated sodium channels, resulting in a potentially lethal inhibition of neurotransmission.

Prostaglandin E2 Has No Effect on Two Components of Tetrodotoxin-Resistant Na+ Current in Mouse Dorsal Root Ganglion

open access: yesJournal of Pharmacological Sciences, 2007
One possible mechanism underlying inflammation-induced sensitization of the primary afferent neuron is the upregulation of tetrodotoxin-resistant (TTX-R) Na+ current by inflammatory mediators such as prostaglandins.

Accumulation of Dense Core Vesicles in Hippocampal Synapses Following Chronic Inactivity. [PDF]

open access: yes, 2018
The morphology and function of neuronal synapses are regulated by neural activity, as manifested in activity-dependent synapse maturation and various forms of synaptic plasticity.

Enhanced Adenosine Triphosphate Release From the Urothelium of Patients With Painful Bladder Syndrome:A Possible Pathophysiological Explanation [PDF]

open access: yes, 2007
Purpose: We established the level of adenosine triphosphate release by the urothelium in patients with painful bladder syndrome and compared it with that from the normal human bladder.

Does Ocean Sunfish Mola spp. (Tetraodontiformes: Molidae) Represent a Risk for Tetrodotoxin Poisoning in the Portuguese Coast?

open access: yesMarine Drugs, 2022
Tetrodotoxin (TTX) is a potent neurotoxin naturally occurring in terrestrial and marine organisms such as pufferfish. Due to the risk of TTX poisoning, fish of Tetraodontidae family and other puffer-related species must not be placed in the EU markets ...

The neonatal splice variant of Nav1.5 potentiates in vitro invasive behaviour of MDA-MB-231 human breast cancer cells [PDF]

open access: yes, 2007
Upregulation of functional voltage-gated Na+ channels (VGSCs) occurs in metastatic human breast cancer (BCa) in vitro and in vivo. The present study aimed to ascertain the specific involvement of the 'neonatal' splice variant of Nav1.5 (nNav1.5), thought

Chronic In Vivo Effects of Repeated Exposure to Low Oral Doses of Tetrodotoxin: Preliminary Evidence of Nephrotoxicity and Cardiotoxicity

open access: yesToxins, 2019
Tetrodotoxin (TTX) is one of the most potent naturally occurring neurotoxins. Initially TTX was associated with human food intoxications in Japan, but nowadays, concerns about the human health risks posed by TTX have increased in Europe after the ...
