Surface chemistry of lipid raft and amyloid Aβ (1-40) Langmuir monolayer

Colloids and Surfaces B: Biointerfaces, 2011
[Display omitted] ► Surface chemistry and in situ spectroscopy of lipid raft and Aβ (1-40) Langmuir monolayer were studied. ► It was revealed that the lipid raft Langmuir monolayer was unstable at the air–water interface. ► Adsorption of Aβ (1-40) on the

Analysis of Lipids and Lipid Rafts in Borrelia

2017
Lipid rafts are membrane microdomains that are involved in cellular processes such as protein trafficking and signaling processes, and which play a fundamental role in membrane fluidity and budding. The lipid composition of the membrane and the biochemical characteristics of the lipids found within rafts define the ability of cells to form microdomains

Rafting on the Plasma Membrane: Lipid Rafts in Signaling and Disease

2023
The plasma membrane is not a uniform phospholipid bilayer; it has specialized membrane nano- or microdomains called lipid rafts. Lipid rafts are small cholesterol and sphingolipid-rich plasma membrane islands. Although their existence was long debated, their presence in the plasma membrane of living cells is now well accepted with the advent of super ...

Domains and Rafts in Lipid Membranes

Angewandte Chemie International Edition, 2003
Abstract“It takes a membrane to make sense out of disorder in biology. You have to be able to catch energy and hold it, storing precisely the needed amount and releasing it in measured shares”. So wrote Lewis Thomas in The Lives of Cells. Domains and rafts are shown in the present Review to play an important role in this amazing behavior of lipid ...

Lipid Rafts in Neurodegeneration and Neuroprotection

Molecular Neurobiology, 2013
The collective properties of the lipids that form biological membranes give rise to a very high level of lateral organization within the membranes. Lipid-driven membrane organization allows the segregation of membrane-associated components into specific lipid rafts, which function as dynamic platforms for signal transduction, protein processing, and ...

Lipid Rafts and Redox Signaling

Antioxidants & Redox Signaling, 2007
In addition to the amplifying action of enzymes in the cell-signaling cascade, another important mechanism has been shown to amplify the signals massively when ligands bind to their receptors, which is characterized by clustering of membrane lipid microdomains or lipid rafts and formation of various signaling platforms.

Bacterial subversion of lipid rafts

Current Opinion in Microbiology, 2004
Bacteria rely on numerous basic cellular functions of their target cells to reach successful infection. The recent discovery that the plasma membrane contains specialized microdomains, called lipid rafts, with many specific functions but in particular with the ability to concentrate signaling molecules, has therefore attracted the attention of cellular

Lipid rafts and signal transduction

Nature Reviews Molecular Cell Biology, 2000
Signal transduction is initiated by complex protein-protein interactions between ligands, receptors and kinases, to name only a few. It is now becoming clear that lipid micro-environments on the cell surface -- known as lipid rafts -- also take part in this process. Lipid rafts containing a given set of proteins can change their size and composition in

Lipid rafts in lymphocyte activation

Microbes and Infection, 2004
The existence of sphingolipid- and cholesterol-rich membrane microdomains called "lipid rafts", as well as their role in lymphocyte biology, has been widely debated during the last few years. Plasma membrane microdomains seem to be primarily involved in initiation and propagation of the signal transduction cascade associated with lymphocyte activation.
