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.

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 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

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 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.

Bacterial subversion of lipid rafts
Current Opinion in Microbiology, 2004Bacteria 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: Feeling is Believing
Physiology, 2004In the late 1990s, accumulated evidence led to the proposal that biological membranes are composed of microdomains of different lipids, which form functional “rafts.” Recent work using atomic force microscopy has given us new insights into the factors influencing the formation and behavior of these physiological microenvironments

Lipid rafts and signal transduction
Nature Reviews Molecular Cell Biology, 2000Signal 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
