Tetrodotoxin, fungal pathogen infection, and bacterial microbiome associations are variable in the skin microecosystems of two Taricha newt species

Frontiers in Amphibian and Reptile Science
A diverse metabolome exists on amphibian skin that mediates interactions between hosts and skin microbiomes. Tetrodotoxin is one such metabolite that occurs across a variety of taxa, and is particularly well studied in newts of the genus Taricha that are

Cancer pain: current practice and emerging targets

British Journal of Pharmacology, EarlyView.
Cancer pain (CP) arises from a complex interplay between the tumour and its microenvironment. Many patients experience a mixed pain phenotype that encompasses nociceptive, neuropathic and neuroinflammatory mechanisms, and vary across tumour type and disease stage. Despite decades of intensive research, the mainstay of cancer pain treatment is still non‐

Inhibition of late sodium current prevents pathological hyperactivation of calcium/calmodulin‐dependent protein kinase IIδ in a murine model of acute doxorubicin‐related cardiotoxicity

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Doxorubicin (DOX) is a highly effective anthracycline, whose clinical application for cancer is limited by cardiotoxicity. The mechanisms underlying doxorubicin‐induced toxic cardiomyopathy (DICM) involve electrophysiological remodelling with intracellular Na+ overload because of increased late INa and hyperactivation of

Selective modulation of NaV channel gating counteracts aberrant hyperexcitability and rescues motor function and survival in a model of spinal muscular atrophy

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 ...

NMDA receptor subunit‐dependent analysis of radiprodil inhibition in neonatal male rat substantia nigra dopaminergic neurons

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.

Phloroglucinol inhibits human ureteral contractions via activation of cAMP‐PKA pathway

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Phloroglucinol is used to treat renal colic, especially when non‐steroidal anti‐inflammatory drugs are contraindicated. This study aimed to clarify its mechanism by examining effects on human ureteral contractility and underlying signalling pathways. Experimental Approach Urinary levels of neurokinin A (NKA), substance P

High‐resolution pressure myography reveals pressure‐dependent local contractile and geometric dynamics in the renal pelvis and ureter

British Journal of Pharmacology, EarlyView.
Background and Purpose Coordinated peristalsis between the renal pelvis and ureter is critical for effective urine transport. However, intraluminal pressure impact on upper urinary tract (UUT) contractility and pharmacologic responsiveness remains poorly understood due to absence of suitable investigative methods.

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.

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

Marine 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

Persistent in vitro nociceptor hyperexcitability and axonal retraction produced by repeated paclitaxel doses

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.
