Extremely Potent Block of Bacterial Voltage-Gated Sodium Channels by µ-Conotoxin PIIIA
µ-Conotoxin PIIIA, in the sub-picomolar, range inhibits the archetypal bacterial sodium channel NaChBac (NavBh) in a voltage- and use-dependent manner.

Effect of channel block on the spiking activity of excitable membranes in a stochastic Hodgkin-Huxley model [PDF]
The influence of intrinsic channel noise on the spontaneous spiking activity of poisoned excitable membrane patches is studied by use of a stochastic generalization of the Hodgkin-Huxley model.

Modeled channel distributions explain extracellular recordings from cultured neurons sealed to microelectrodes [PDF]
Amplitudes and shapes of extracellular recordings from single neurons cultured on a substrate embedded microelectrode depend not only on the volume conducting properties of the neuron-electrode interface, but might also depend on the distribution of ...

NaV1.6 and NaV1.7 channels are major endogenous voltage-gated sodium channels in ND7/23 cells.
ND7/23 cells are gaining traction as a host model to express peripheral sodium channels such as NaV1.8 and NaV1.9 that have been difficult to express in widely utilized heterologous cells, like CHO and HEK293.

Voltage-gated sodium channels: biophysics, pharmacology, and related channelopathies
Voltage-gated sodium channels (VGSC) are multi-molecular protein complexes expressed in both excitable and non-excitable cells. They are primarily formed by a pore-forming multi-spanning integral membrane glycoprotein (α-subunit) that can be associated ...

Voltage-gated sodium channels potentiate the invasive capacities of human non-small-cell lung cancer cell lines. [PDF]
Ionic channel activity is involved in fundamental cellular behaviour and participates in cancerous features such as proliferation, migration and invasion which in turn contribute to the metastatic process.

Inhibition of voltage-gated sodium channels by sumatriptan bioisosteres
Voltage-gated sodium channels are known to play a pivotal role in perception and transmission of pain sensations. Gain-of-function mutations in the genes encoding the peripheral neuronal sodium channels, hNav1.7-1.9, cause human painful diseases.

Molecular basis of ion permeability in a voltage-gated sodium channel [PDF]
Voltage‐gated sodium channels are essential for electrical signalling across cell membranes. They exhibit strong selectivities for sodium ions over other cations, enabling the finely tuned cascade of events associated with action potentials.

Venomous secretions from marine snails of the Terebridae family target acetylcholine receptors [PDF]
Venoms from cone snails (Conidae) have been extensively studied during the last decades, but those from other members of the suborder Toxoglossa, such as of Terebridae and Turridae superfamilies attracted less interest so far. Here, we report the effects
