Intermolecular Headgroup Interaction and Hydration as Driving Forces for Lipid Transmembrane Asymmetry

Sylvie Roke, Nikolay Smolentsev, Halil Ibrahim Okur, Cornelis Ulrich Lütgebaucks

Variations between the inner and outer leaflets of cell membranes are crucial for cell functioning and signaling, drug–membrane interactions, and the formation of lipid domains. Transmembrane asymmetry can in principle be comprised of an asymmetric charge ...

GSDMD membrane pore formation constitutes the mechanism of pyroptotic cell death

Henning Paul-Julius Stahlberg

Pyroptosis is a lytic type of cell death that is initiated by inflammatory caspases. These caspases are activated within multi-protein inflammasome complexes that assemble in response to pathogens and endogenous danger signals. Pyroptotic cell death has be ...

A Pd-Cu2O nanocomposite as an effective synergistic catalyst for selective semi-hydrogenation of the terminal alkynes only

Shuliang Yang, Li Peng

A new type lead-free catalyst of a Pd-Cu2O nanocomposite was developed for highly selective semi-hydrogenation of alkynes. With unprecedented selectivity for the semi-hydrogenation of terminal alkynes to alkenes, we show for the first time that the catalys ...

Shape-Selective Assembly of Anisotropic, Deformable Microcomponents Using Bottom-Up Micromanufacturing

Gunjan Agarwal

A technique for shape-selective directed assembly of anisotropic, deformable, chemically-identical microcomponents onto patterned rigid templates based on shape and size differences is modeled and demonstrated. The assembly method not only controls the sel ...

Molecularly Engineered Self-Assembling Membranes for Cell-Mediated Degradation

Jeffrey Alan Hubbell, Daniela Sofia Dias Ferreira, Yi-An Lin

The use of peptide engineering to develop self-assembling membranes that are responsive to cellular enzyme activities is reported. The membranes are obtained by combining hyaluronan (HA) and a rationally designed peptide amphiphile (PA) containing a proteo ...

Pad printing 1-10 mm thick elastomer membranes for DEAs

Herbert Shea, Samuel Rosset, Alexandre Poulin

We present a technique for stamping patterned silicone elastomer membranes with thicknesses ranging from 1 to 10 um. Silicone elastomers are becoming the material of choice for dielectric elastomer transducers. The variety of readily available materials, t ...

Lipid Builder: A Framework To Build Realistic Models for Biological Membranes

Matteo Dal Peraro, Thomas Lemmin, Giorgio Elikem Tamo, Christophe Bovigny, Nicolas Grégoire Maïno

The physical and chemical characterization of biological membranes is of fundamental importance for understanding the functional role of lipid bilayers in shaping cells and organelles, steering vesicle trafficking and promoting membrane-protein signaling. ...

Monitoring the Cellular Cholesterol Distribution via nanoSIMS Imaging

Mustafa Demir

Cholesterol is a very important lipid, manufactured by all animal cells for their use. About 20-25% of total daily cholesterol production occurs in the liver; other sites that have higher synthesis rate are intestine, adrenal glands and reproductive organs ...
