Yet more evidence that non-aqueous myelin lipids can be directly imaged with ultrashort echo time (UTE) MRI on a clinical 3T scanner: a lyophilized red blood cell membrane lipid study

NeuroImage
Direct imaging of semi-solid lipids, such as myelin, is of great interest as a noninvasive biomarker of neurodegenerative diseases. Yet, the short T2 relaxation times of semi-solid lipid protons hamper direct detection through conventional magnetic ...

Fluorescent Lipids: Functional Parts of Fusogenic Liposomes and Tools for Cell Membrane Labeling and Visualization

Molecules, 2012
In this paper a rapid and highly efficient method for controlled incorporation of fluorescent lipids into living mammalian cells is introduced. Here, the fluorescent molecules have two consecutive functions: First, they trigger rapid membrane fusion ...

Lipids in membrane protein structures

Biochimica et Biophysica Acta (BBA) - Biomembranes, 2004
This review describes the recent knowledge about tightly bound lipids in membrane protein structures and deduces general principles of the binding interactions. Bound lipids are grouped in annular, nonannular, and integral protein lipids. The importance of lipid binding for vertical positioning and tight integration of proteins in the membrane, for ...

The effect of changes in plasma membrane lipid composition on the heat sensitivity of Hepatoma tissue culture cells and selected plasma membrane enzymes [PDF]

, 1990
Hepatoma Tissue Culture (HTC) cells grown in the presence of 60µM arachidonic acid for 24, 36 and 48 hours became progressively more thermosensitive than control cells.

Digalactosyl-diacylglycerol-deficiency lowers the thermal stability of thylakoid membranes [PDF]

, 2010
We investigated the effects of digalactosyl-diacylglycerol (DGDG) on the organization and thermal stability of thylakoid membranes, using wild-type Arabidopsis thaliana and the DGDG-deficient mutant, dgd1. Circular-dichroism measurements reveal that DGDG-

Lipid Organization of the Plasma Membrane

Journal of the American Chemical Society, 2014
The detailed organization of cellular membranes remains rather elusive. Based on large-scale molecular dynamics simulations, we provide a high-resolution view of the lipid organization of a plasma membrane at an unprecedented level of complexity. Our plasma membrane model consists of 63 different lipid species, combining 14 types of headgroups and 11 ...

Mechanisms regulating the acyl chain composition of membrane lipids in S. cerevisiae [PDF]

, 2011
The goal of the research described in this thesis was to identify the genes/enzymes involved in acyl chain remodeling of the major membrane lipid phosphatidylcholine (PC) in the model eukaryote S. cerevisiae. A database search yielded 75 candidates with (
