Quantum coherence on selectivity and transport of ion channels [PDF]
arXiv, 2022 Recently, it has been suggested that ion channel selectivity filter may exhibit quantum coherence, which may be appropriate to explain ion selection and conduction processes. Potassium channels play a vital role in many physiological processes. One of their main physiological functions is the efficient and highly selective transfer of K+ ions through ...

Nature Communications, 2017 Steviol glycosides are sweet-tasting compounds isolated from a South American shrub and are increasingly used as sweeteners in foods and beverages. Philippaertet al. demonstrate that steviol glycosides potentiate Ca2+-dependent TRPM5 activity and promote

FEBS Letters, EarlyView.Venom peptides have shown promise in treating pain. Our study uses computer screening to identify a peptide that targets a sodium channel (NaV1.7) linked to chronic pain. We produced the peptide in the laboratory and refined its design, advancing the search for innovative pain therapies.

Traveling ion channel density waves affected by a conservation law [PDF]
, 2006 A model of mobile, charged ion channels embedded in a biomembrane is investigated. The ion channels fluctuate between an opened and a closed state according to a simple two-state reaction scheme whereas the total number of ion channels is a conserved quantity.

Efficient Generation of Membrane and Solvent Tetrahedral Meshes for Ion Channel Finite Element Calculation [PDF]
arXiv, 2022 A finite element solution of an ion channel dielectric continuum model such as Poisson-Boltzmann equation (PBE) and a system of Poisson-Nernst-Planck equations (PNP) requires tetrahedral meshes for an ion channel protein region, a membrane region, and an ionic solvent region as well as an interface fitted irregular tetrahedral mesh of a simulation box ...

The Saccharomyces cerevisiae amino acid transporter Lyp1 has a broad substrate spectrum
FEBS Letters, EarlyView.In Saccharomyces cerevisiae, Yeast Amino acid Transporter family members mediate the import of amino acids, ranging from substrate specialists to generalists. Here, we show that the specialist transporter, Lyp1, has a broader substrate spectrum than previously described, with affinity constants spanning from micromolar to millimolar.

TRP Channels Regulation of Rho GTPases in Brain Context and Diseases
Frontiers in Cell and Developmental Biology, 2020 Neurological and neuropsychiatric disorders are mediated by several pathophysiological mechanisms, including developmental and degenerative abnormalities caused primarily by disturbances in cell migration, structural plasticity of the synapse, and blood ...

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

ION CHANNELS OF NOCICEPTION [PDF]
Annual Review of Physiology, 1999 ▪ Abstract Nociceptors are the first cells in the series of neurons that lead to the sensation of pain. The essential functions of nociceptors—transducing noxious stimuli into depolarizations that trigger action potentials, conducting the action potentials from the peripheral sensory site to the synapse in the central nervous system, and converting ...
