British Journal of Pharmacology, EarlyView.Abstract Background and Purpose Positive allosteric modulators bind to secondary binding sites on the receptor and alter receptor conformation and activation, changing agonist potency and efficacy. PTC‐174 is a novel NMDA receptor positive allosteric modulator that particularly enhances activity of receptors containing GluN2C or GluN2D subunits.

British Journal of Pharmacology, EarlyView.Background and Purpose Spinal muscular atrophy (SMA) is a motor neuron disease caused by SMN1 gene loss, leading to reduced survival motor neuron (SMN) protein and progressive motor neuron degeneration. Although SMN‐restoring therapies improve outcomes, residual disease burden and non‐curative efficacy underscore the need for complementary treatments ...

British Journal of Pharmacology, EarlyView.Abstract Background and Purpose Radiprodil is a GluN2B subunit selective NMDA receptor negative allosteric modulator which is currently under clinical investigation as a possible anti‐epileptic drug for paediatric use. Our goal was to investigate the inhibition of dopaminergic neuron NMDA responses by radiprodil.

An improved competitive inhibition enzymatic immunoassay method for tetrodotoxin quantification
Biological Procedures Online, 2012 Quantifying tetrodotoxin (TTX) has been a challenge in both ecological and medical research due to the cost, time and training required of most quantification techniques.

The FEBS Journal, EarlyView.Repeated paclitaxel exposure causes long‐lasting nociceptor hyperexcitability and axonal retraction in adult sensory neurons. Using a long‐term primary nociceptor culture, we show that hyperexcitability is mediated by sequential upregulation of NaV1.8, TRPV1, TRPA1, and TRPM8 channels.

Dynamic memory in rodent C‐fibres and its impact on spinal nociceptive processing
The Journal of Physiology, EarlyView.Abstract figure legend Nociceptive C‐fibres display activity‐dependent slowing (ADS) whereby successive action potentials are conducted progressively slower thus regulating the temporal relay of pain signals. This study shows that the ADS induced by short stimulus trains (which mimic stimulus evoked firing, shown in orange) is modified by prior ...

Tetrodotoxin Sensitivity of the Vertebrate Cardiac Na+ Current
Marine Drugs, 2011 Evolutionary origin and physiological significance of the tetrodotoxin (TTX) resistance of the vertebrate cardiac Na+ current (INa) is still unresolved.

Trafficking and potentiation of Nav1.7 and Nav1.8 channels are mediated by IQGAP1
The Journal of Physiology, EarlyView.Abstract figure legend IQGAP1 binds to the voltage‐gated Nav1.7 and Nav1.8 channels and TRPA1 channels in sensory neurons. Inflammatory mediators (IM), including PGE2 and TNFα, released during nerve injury and inflammation activate intracellular signalling messengers such as PKA, p38 MAPK and Cdc42 through their respective receptors.

Spatial variability and depuration of tetrodotoxin in the bivalve Paphies australis from New Zealand
Toxicon: X, 2019 Tetrodotoxin (TTX) is a potent neurotoxin responsible for many human intoxications globally. Despite its potency and widespread occurrence in taxonomically diverse species, the primary source of TTX remains uncertain.

Toxins, 2020 Some nemertean species from the genus Cephalothrix accumulate tetrodotoxin (TTX) in extremely high concentrations. The current study is the first to provide high-performance liquid chromatography–tandem mass spectrometry (HPLC–MS/MS) data on tetrodotoxin
