Mimicking the Mammalian Plasma Membrane: An Overview of Lipid Membrane Models for Biophysical Studies

open access: yesBiomimetics, 2020
Cell membranes are very complex biological systems including a large variety of lipids and proteins. Therefore, they are difficult to extract and directly investigate with biophysical methods.

Ordered Domain (Raft) Formation in Asymmetric Vesicles and Its Induction upon Loss of Lipid Asymmetry in Artificial and Natural Membranes

open access: yesMembranes, 2022
Lipid asymmetry, the difference in the lipid composition in the inner and outer lipid monolayers (leaflets) of a membrane, is an important feature of eukaryotic plasma membranes.

Lipid Transporters Beam Signals from Cell Membranes

open access: yesMembranes, 2021
Lipid composition in cellular membranes plays an important role in maintaining the structural integrity of cells and in regulating cellular signaling that controls functions of both membrane-anchored and cytoplasmic proteins.

Membrane curvature sorts lipids [PDF]

open access: yesEMBO reports, 2005
The enrichment of sphingolipids and cholesterol in the mammalian plasma membrane, and unsaturated phosphatidylcholine (PC) in the endoplasmic reticulum, requires lipid sorting in the Golgi apparatus. Most sphingolipids are synthesized in the Golgi lumen (Holthuis & Levine, 2005).

How cholesterol stiffens unsaturated lipid membranes

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance Cholesterol regulates critical cell functions, including lysis, viral budding, and antibiotic resistance, by modifying the bending rigidity of cell membranes; i.e., the ability of membranes to bend or withstand mechanical stresses.

Membrane Heterogeneity Beyond the Plasma Membrane

open access: yesFrontiers in Cell and Developmental Biology, 2020
The structure and organization of cellular membranes have received intense interest, particularly in investigations of the raft hypothesis. The vast majority of these investigations have focused on the plasma membrane of mammalian cells, yielding ...

The effects of molecular and nanoscopic additives on phospholipid membranes

open access: yesFrontiers in Physics, 2023
Lipid bilayers—the main matrix of cell membranes—are a paradigm of soft molecular assemblies whose properties have been evolutionarily optimized to satisfy the functional requirements of cells.

High-dimensional super-resolution imaging reveals heterogeneity and dynamics of subcellular lipid membranes

open access: yesNature Communications, 2020
Lipid membranes are found in most intracellular organelles, and their heterogeneities play an essential role in regulating the organelles’ biochemical functionalities.

The impact of physiologically relevant temperatures on physical properties of thylakoid membranes: a molecular dynamics study

open access: yesPhotosynthetica, 2023
Thylakoid membranes are energy-converting membranes with a unique lipid composition. Though the membranes are primarily composed of proteins, their photosynthetic function is strongly influenced by the lipid constituents.

Interactions of α-synuclein oligomers with lipid membranes.

open access: yesBiochimica et Biophysica Acta - Biomembranes, 2020
Parkinson's disease is an increasingly prevalent and currently incurable neurodegenerative disorder. At the molecular level, this disease is characterized by the formation of aberrant intracellular protein deposits known as Lewy bodies.
