Charge-induced phase separation in lipid membranes [PDF]

, 2014
The phase separation in lipid bilayers that include negatively charged lipids is examined experimentally. We observed phase-separated structures and determined the membrane miscibility temperatures in several binary and ternary lipid mixtures of ...

Lipid composition of the cancer cell membrane

Journal of Bioenergetics and Biomembranes, 2020
Cancer cell possesses numerous adaptations to resist the immune system response and chemotherapy. One of the most significant properties of the neoplastic cells is the altered lipid metabolism, and consequently, the abnormal cell membrane composition ...

Aglycon diversity of brain sterylglucosides: structure determination of cholesteryl- and sitosterylglucoside[S]

Journal of Lipid Research, 2016
To date, sterylglucosides have been reported to be present in various fungi, plants, and animals. In bacteria, such as Helicobacter pylori, proton NMR spectral analysis of isolated 1-O-cholesteryl-β-d-glucopyranoside (GlcChol) demonstrated the presence ...

Visualizing NBD-lipid Uptake in Mammalian Cells by Confocal Microscopy

Bio-Protocol, 2023
Eukaryotic cells use a series of membrane transporters to control the movement of lipids across their plasma membrane. Several tools and techniques have been developed to analyze the activity of these transporters in the plasma membrane of mammalian ...

Alterations of membrane curvature during influenza virus budding [PDF]

, 2014
Influenza A virus belongs to the Orthomyxoviridae family. It is an enveloped virus that contains a segmented and negative-sense RNA genome. Influenza A viruses cause annual epidemics and occasional major pandemics, are a major cause of morbidity and ...

The Phase Behavior of Mixed Lipid Membranes in Presence of the Rippled Phase

, 2007
We propose a model describing liquid-solid phase coexistence in mixed lipid membranes by including explicitly the occurrence of a rippled phase. For a single component membrane, we employ a previous model in which the membrane thickness is used as an ...

Effect of charged lipids on the ionization behavior of glutamic acid containing transmembrane helices [PDF]

, 2020
Transmembrane proteins make up critical components of living cells. Protein function can be greatly impacted by the charged state of its respective components, the side chains of amino acid residues.

Pore formation in lipid membrane II: Energy landscape under external stress

Scientific Reports, 2017
Lipid membranes are extremely stable envelopes allowing cells to survive in various environments and to maintain desired internal composition. Membrane permeation through formation of transversal pores requires substantial external stress.

Functional Peptides from SARS-CoV-2 Binding with Cell Membrane: From Molecular Dynamics Simulations to Cell Demonstration

Cells, 2022
Herein, we have verified the interaction between the functional peptides from the SARS-CoV-2 and cell membrane, and we further proved that peptides exhibit little membrane disruption.

Undulation instability in a bilayer lipid membrane due to electric field interaction with lipid dipoles [PDF]

, 2010
Bilayer lipid membranes [BLMs] are an essential component of all biological systems, forming a functional barrier for cells and organelles from the surrounding environment.
