The Role of Lipid Microdomains in Virus Biology
2004Many of the highly pathogenic viruses including influenza virus, HIV and others of world wide epidemiological importance are enveloped and possess a membrane around the nucleocapsid containing the viral genome. Viral membrane is required to protect the viral genome and provide important functions for attachment, morphogenesis and transmission.

Lipid microdomains – plant membranes get organized
Trends in Plant Science, 2005The plant plasma membrane is now known to be a more sophisticated structure than was previously thought. Sebastien Mongrand et al. and Georg Borner et al. have isolated specific plasma membrane microdomains ('lipid rafts') that are enriched in sterols and sphingolipids.

PROTEOMICS, 2006
Biological membranes are compartmentalized into microdomains that exhibit particular lipid and protein compositions. Membrane microdomains, such as tetraspanin-enriched microdomains and lipid rafts, have been suggested to play a role in a variety of physiological and pathological processes. Therefore, the characterization of the protein compositions of

Accelerated Enzymatic Galactosylation of N-Acetylglucosaminolipids in Lipid Microdomains
Journal of the American Chemical Society, 2012A fluoro-tagged N-acetylglucosamine-capped glycolipid that can form lipid microdomains in fluid phospholipid bilayers has been shown to be enzymatically galactosylated by bovine β(1,4)-galactosyltransferase. MALDI MS, HPLC, and LC-MS revealed that the rate of enzymatic transformation was significantly enhanced by lipid clustering; at a 1% mol/mol ...

Phase Separation of Lipid Microdomains Controlled by Polymerized Lipid Bilayer Matrices
Langmuir, 2009We developed a micropatterned model biological membrane on a solid substrate that can induce phase separation of lipid microdomains in a designed geometry. Micropatterned lipid bilayers were generated by the photolithographic polymerization of a diacetylene phospholipid, 1,2-bis(10,12-tricosadiynoyl)-sn-glycero-3-phosphocholine (DiynePC).

Regulation of Plant Transporters by Lipids and Microdomains
2010Transporters in the broad sense, that is, carriers, pumps, and channels, are proteins inserted in a lipid bilayer separating two cellular compartments. This lipid bilayer is not only the physical support of such proteins, but also a powerful way to regulate their activity.

Lipid Microdomains: Structural Correlations, Fluctuations, and Formation Mechanisms
Physical Review Letters, 2010Compositional lipid microdomains ("lipid rafts") in mammalian plasma membranes are believed to facilitate many important cellular processes. While several physically distinct scenarios predicting the presence of finite-sized microdomains in vivo have been proposed in the past, direct experimental verification or falsification of model predictions has ...

Implications of lipid microdomains for membrane curvature, budding and fission
Current Opinion in Cell Biology, 2001Recent studies have highlighted the importance of monolayer and bilayer curvature for the budding and fission of biological membranes. Other lines of research, addressing the structure of planar biological membranes, have revealed the existence of cholesterol-based membrane microdomains.

Contrasting roles of oxidized lipids in modulating membrane microdomains
Biochimica et Biophysica Acta (BBA) - Biomembranes, 2019Lipid rafts display a lateral heterogeneity forming membrane microdomains that hold a fundamental role on biological membranes and are indispensable to physiological functions of cells. Oxidative stress in cellular environments may cause lipid oxidation, changing membrane composition and organization, thus implying in effects in cell signaling and even

Lipid microdomains and membrane trafficking in mammalian cells
Histochemistry and Cell Biology, 1997This overview summarizes the data for how epithelial cells sort and deliver proteins and lipids to the apical and basolateral cell surface domains. The basolateral pathway uses a Rab-SNARE mechanism for docking and fusion, while the apical route employs a different machinery. This latter mechanism is based on lipid microdomains, composed of clusters of
