Preparation of PVDF/PMMA composite membrane with green solvent for seawater desalination by gap membrane distillation

, 2023
With the increasing demand for freshwater, desalination of seawater and its alternatives has become a major priority for the scientific community. This work studied the preparation of a flat-sheet poly(vinylidene fluoride) (PVDF)/poly(methyl methacrylate)

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

FEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Solubilization of lipids and membrane proteins into nanodiscs: Mode of action and applications of SMA copolymers

, 2016
Cell membranes separate the inside and outside of cells. Membrane proteins in the cell membrane control the traffic of molecules across the membrane and are therefore targets for a lot of drugs: about 50 % of all approved drugs target a membrane protein!

On the origin of membrane potential in membranes with polarizable nanopores [PDF]

, 2018
We report a new mechanism for the generation of membrane potential in polarizable nanoporous membranes separating electrolytes with different concentrations.

Facile hydrophobic modification of hydrophilic membranes by fluoropolymer coating for direct contact membrane distillation

, 2023
Membrane distillation (MD) is a promising desalination technology as it is less sensitive to feed's salinity and can handle high-salinity water. However, the industrial application of MD is restricted by the limited availability of cost-effective ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Membrane potential-dependent calcium transport in right-side-out plasma membrane vesicles from Zea mays L. roots

, 1994
Right-side-out plasma membrane Vesicles isolated from Zea mays roots were used to study membrane potential (Delta Psi)-dependent Ca2+ transport. Membrane potentials were imposed on the vesicles using either K+ concentration gradients and valinomycin or ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
