Lipid rafts are plasma membrane microdomains enriched in sphingolipids and cholesterol. These domains have been suggested to serve as platforms for various cellular events, such as signaling and membrane trafficking. However, little is known about the distribution and dynamics of lipids in these microdomains.

The time-averaged lateral organization of the lipids and proteins that make up mammalian cell membranes continues to be the subject of intense interest and debate. Since the introduction of the fluid mosaic model almost 50 years ago, the "lipid raft hypothesis" has emerged as a popular concept that has captured the imagination of a large segment of the

The notion that microdomains enriched in certain specialized lipids exist in membranes has been both attractive and controversial since it was first proposed that such domains, termed rafts, might act as apical sorting devices in epithelial cells. The observation that certain lipids are not extractable in cold nonionic detergent supports the raft ...

Lipid rafts in lymphocyte activation
Microbes and Infection, 2004The 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.

Lipid microenvironments in the plasma membrane are known to influence many signal transduction pathways. Several of those pathways are critical for both the etiology and treatment of depression. Further, several signaling proteins are modified, covalently, by lipids, a process that alters their interface with the microenvironments mentioned above. This

Domains and Rafts in Lipid Membranes
Angewandte Chemie International Edition, 2003Abstract“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 Exosome Biogenesis
Biochemistry (Moscow), 2020Exosomes (secreted extracellular vesicles formed in the intracellular vesicular transport system) play a crucial role in distant cell-cell communication. Exosomes transfer active forms of various biomolecules; the molecular composition of the exosomal cargo is a result of targeted selection and depends on the type of producer cells.

Lipid Rafts in Neurodegeneration and Neuroprotection
Molecular Neurobiology, 2013The 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 ...

Analysis of Lipids and Lipid Rafts in Borrelia
2017Lipid 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

Lipid Rafts and Redox Signaling
Antioxidants & Redox Signaling, 2007In 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.
