Trends in Cell Biology, 1998 The thin membrane of the endoplasmic reticulum matures into the thick plasma membrane in the Golgi apparatus. Along the way, the concentrations of cholesterol and sphingolipids increase. Here, Gerrit van Meer discusses how this phenomenon may reflect an intricate lipid-protein sorting machinery.

Lipids and membrane lateral organization [PDF]
Frontiers in Physiology, 2010 Shortly after the elucidation of the very basic structure and properties of cellular membranes, it became evident that cellular membranes are highly organized structures with multiple and multi-dimensional levels of order.

Lipid and Lipidation in Membrane Fusion
The Journal of Membrane Biology, 2022 Membrane fusion plays a lead role in the transport of vesicles, neurotransmission, mitochondrial dynamics, and viral infection. There are fusion proteins that catalyze and regulate the fusion. Interestingly, various types of fusion proteins are present in nature and they possess diverse mechanisms of action.

Membrane Lipids in Ultra-High-Risk Patients: Potential Predictive Biomarkers of Conversion to Psychosis. [PDF]
Nutrients, 2023 International audienceAlterations in membrane lipids are reported in schizophrenia. However, no conclusion can be drawn regarding the extended and predictive value of these alterations in persons at ultra-high risk of psychosis (UHR).

Drought and heat stress mediated activation of lipid signaling in plants: a critical review
Frontiers in Plant Science, 2023 Lipids are a principal component of plasma membrane, acting as a protective barrier between the cell and its surroundings. Abiotic stresses such as drought and temperature induce various lipid-dependent signaling responses, and the membrane lipids ...

Lipid membranes with an edge [PDF]
Physical Review E, 2002 Consider a lipid membrane with a free exposed edge. The energy describing this membrane is quadratic in the extrinsic curvature of its geometry; that describing the edge is proportional to its length. In this note we determine the boundary conditions satisfied by the equilibria of the membrane on this edge, exploiting variational principles.

The Crucial Roles of Phospholipids in Aging and Lifespan Regulation
Frontiers in Physiology, 2021 Phospholipids are major membrane lipids that consist of lipid bilayers. This basic cellular structure acts as a barrier to protect the cell against various environmental insults and more importantly, enables multiple cellular processes to occur in ...

FEBS Letters, 1974 Today, as in 1964, those who are concerned with membranes are broadly divided into two main groups: investigators who work on lipids and others who study proteins. Whether one pursues mainly this aspect or that is often more the result of individual interest and background rather than the outcome of a decision that one particular aspect of membranes is

Heat Stress Dictates Microbial Lipid Composition along a Thermal Gradient in Marine Sediments
Frontiers in Microbiology, 2017 Temperature exerts a first-order control on microbial populations, which constantly adjust the fluidity and permeability of their cell membrane lipids to minimize loss of energy by ion diffusion across the membrane.

Spiroplasma membrane lipids [PDF]
Journal of Bacteriology, 1985 Membranes of six spiroplasma strains belonging to different Spiroplasma species and subgroups were isolated by a combination of osmotic lysis and sonication in the presence of EDTA to block endogenous phospholipase activity. Analysis of membrane lipids showed that in addition to free and esterified cholesterol the spiroplasmas incorporated exogenous ...
