Gating modulation and potentiation of amiodarone blockage of the Kv10.1 potassium channel bu KB130015, an amiodarone derived molecule

open access: yesChannels
Kv10.1 is a voltage-gated K+ channel whose structure–function relationships remain incompletely understood, and whose ectopic expression is linked to tumorigenesis.

A Quantum-mechanical description of ion motion within the confining potentials of voltage gated ion channels

open access: yes, 2012
Voltage gated channel proteins cooperate in the transmission of membrane potentials between nerve cells. With the recent progress in atomic-scaled biological chemistry it has now become established that these channel proteins provide highly correlated ...

Membrane-Mediated Action of Phosphodiesterase 5 Inhibitors

open access: yesPharmaceutics
Background/Objectives: Phosphodiesterase 5 (PDE5) inhibitors, sildenafil, vardenafil, and tadalafil, activate the cyclic guanosine monophosphate pathway resulting in vascular smooth muscle relaxation.

Mouse TRPA1 function and membrane localization are modulated by direct interactions with cholesterol

open access: yeseLife, 2019
The cation channel TRPA1 transduces a myriad of noxious chemical stimuli into nociceptor electrical excitation and neuropeptide release, leading to pain and neurogenic inflammation.

Beam loading in the nonlinear regime of plasma-based acceleration

open access: yes, 2008
A theory that describes how to load negative charge into a nonlinear, three-dimensional plasma wakefield is presented. In this regime, a laser or an electron beam blows out the plasma electrons and creates a nearly spherical ion channel, which is ...

Complementary DMOS-VMOS integrated circuit structure [PDF]

open access: yes, 1978
A high speed CMOS formed on a single semiconductor substrate includes a DMOS having an asymmetric channel and a VMOS with a relatively short channel length.

Multiple solutions of steady-state Poisson-Nernst-Planck equations with steric effects

open access: yes, 2014
Experiments measuring currents through single protein channels show unstable currents. Channels switch between 'open' or 'closed' states in a spontaneous stochastic process called gating.

TRPV4 activation triggers protective responses to bacterial lipopolysaccharides in airway epithelial cells

open access: yesNature Communications, 2017
LPS is a major component of gram-negative bacterial cell walls, and triggers immune responses in airway epithelium by activating TLR4. Here the authors show that LPS also activates TRPV4, thereby inducing fast defense responses such as nitric oxide ...

Asymmetry of movements in CFTR's two ATP sites during pore opening serves their distinct functions

open access: yeseLife, 2017
CFTR, the chloride channel mutated in cystic fibrosis (CF) patients, is opened by ATP binding to two cytosolic nucleotide binding domains (NBDs), but pore-domain mutations may also impair gating.
