Are voltage-gated sodium channels on the dorsal root ganglion involved in the development of neuropathic pain?

Molecular Pain, 2011
Neuropathic pain is a common clinical condition. Current treatments are often inadequate, ineffective, or produce potentially severe adverse effects. Understanding the mechanisms that underlie the development and maintenance of neuropathic pain will be ...

DNA ligase LigE increases bacterial transformation with damaged extracellular DNA

FEBS Letters, EarlyView.
The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

A nongenomic mechanism for progesterone-mediated immunosuppression: Inhibition of K+ channels, Ca2+ signaling, and gene expression in T lymphocytes [PDF]

, 1998
The mechanism by which progesterone causes localized suppression of the immune response during pregnancy has remained elusive. Using human T lymphocytes and T cell lines, we show that progesterone, at concentrations found in the placenta, rapidly and ...

Beta1 subunits enable fentanyl‐induced BK channel activation and opioid regulation of cerebral artery diameter

FEBS Open Bio, EarlyView.
During the current opioid crisis, the majority of overdose deaths are attributed to ultra‐potent synthetic opioids, such as fentanyl. While fentanyl exerts its action via opioid receptors, we propose that potassium channels in the brain blood vessels may also sense fentanyl.

Replication of seizure-suppressing effects of alpha-linolenic acid on the Drosophila melanogaster paraShudderer mutant

microPublication Biology
Voltage-gated sodium channels are essential for healthy nervous system function. Mutations in voltage-gated sodium channels are associated with a range of seizure conditions.

Ca2+ entry through NaV channels generates submillisecond axonal Ca2+ signaling

eLife, 2020
Calcium ions (Ca2+) are essential for many cellular signaling mechanisms and enter the cytosol mostly through voltage-gated calcium channels. Here, using high-speed Ca2+ imaging up to 20 kHz in the rat layer five pyramidal neuron axon we found that ...

Can the Thermodynamic Hodgkin-Huxley Model of Voltage-Dependent Conductance Extrapolate for Temperature? [PDF]

, 2014
Hodgkin and Huxley (H-H) fitted their model of voltage-dependent conductances to experimental data using empirical functions of voltage. The thermodynamic H-H model of voltage dependent conductances is more physically plausible, as it constrains and ...

Efficacy of Fampridine on Refractory Optic Neuritis in Neuromyelitis Optica Spectrum Disorders

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Neuromyelitis optica spectrum disorders (NMOSD) usually occur with acute refractory optic neuritis (ON). However, there is a lack of efficacious treatments to improve recovery. Since fampridine has been found to improve the prognosis of multiple sclerosis (MS) and MS‐related ON, it is necessary to explore the efficacy of fampridine ...
