Structural heterogeneity of the ion and lipid channel TMEM16F

Horst Vogel

Transmembrane protein 16 F (TMEM16F) is a Ca2+-activated homodimer which functions as an ion channel and a phospholipid scramblase. Despite the availability of several TMEM16F cryogenic electron microscopy (cryo-EM) structures, the mechanism of activation ...

Effects of thermal, mechanical, and electrostatic perturbations on lipid membrane hydration investigated by second harmonic imaging

Seonwoo Lee

Hydrated lipid bilayer membranes are crucial components of cells and organelles, serving as the outer boundary that separates the cellular components from the extracellular environment. Lipid membranes regulate their structures and functions by dynamically ...

Experimental study on velocity distributions, secondary currents, and coherent structures in open channel flow with submerged riparian vegetation

Haoran Shi

Riparian vegetation, which is commonly found in natural rivers and open channels, has a strong influence on flow structures. This paper describes a laboratory experiment on velocity distributions, secondary currents, and coherent structures in narrow open- ...

Water as a contrast agent for imaging interfacial structure and ion transport in giant vesicles

David Roesel

Hydrated lipid bilayer membranes and their asymmetry play a fundamental role in living cells by maintaining and regulating concentration gradients between cells, their environment, and their compartments. They achieve this not only through various channels ...

Passive and active ion permeation through lipid bilayers investigated by second harmonic water imaging

Maksim Eremchev

Lipid membranes are complex and dynamic systems which are known to mediate signaling processes between cells and their environment. To do this multiple ion channels and pumps are involved in controlling the in- and out-flux of various ions (K+, Na+, Mg2+, ...

EPFL2021

Pentameric ligand-gated ion channels (pLGICs) of the Cys-loop receptor family are key players in fast signal transduction throughout the nervous system. They have been shown to be modulated by the lipid environment, however the underlying mechanism is not ...

Could Macroscopic Dark Matter (Macros) Give Rise to Mini-Lightning Flashes out of a Blue Sky without Clouds?

Marcos Rubinstein

A recent study pointed out that macroscopic dark matter (macros) traversing through the Earth’s atmosphere can give rise to hot and ionized channels similar to those associated with lightning leaders. The authors of the study investigated the possibility t ...

Prospects of Observing Ionic Coulomb Blockade in Artificial Ion Confinements

Aleksandra Radenovic, Andrey Chernev, Sanjin Marion

Nanofluidics encompasses a wide range of advanced approaches to study charge and mass transport at the nanoscale. Modern technologies allow us to develop and improve artificial nanofluidic platforms that confine ions in a way similar to single-ion channels ...
