Exosomes are membrane vesicles that are released by cells upon fusion of multivesicular bodies with the plasma membrane. Their molecular composition reflects their origin in endosomes as intraluminal vesicles. In addition to a common set of membrane and cytosolic molecules, exosomes harbor unique subsets of proteins linked to cell type-associated functions. Exosome secretion participates in the eradication of obsolete proteins but several findings, essentially in the immune system, indicate…

Exosomes act as molecular vehicles contributing to cellular cholesterol efflux

It is shown that oligodendroglial cells upregulate their exosome cholesterol secretion upon induction of NPC-like late endosomal/lysosomal cholesterol trapping either by administration of U18666A or by siRNA-mediated down-regulation of NPC1.

The Cell Biology of Exosomes: Historical and Perspectives

Exosomes are present in biological fluids and are potential candidate biomarkers for disease that could also possibly be exploited for therapeutical delivery of drugs.

Shedding light on the cell biology of extracellular vesicles

Extracellular vesicles are now considered as an additional mechanism for intercellular communication, allowing cells to exchange proteins, lipids and genetic material.

Mechanisms of Multivesicular Body Biogenesis and Exosome Release

A novel lipid-dependent pathway for cargo transport to the ILVs in MVBs for exosome formation is identified, providing a basis for understanding the biogenesis and functions of exosomes in the central nervous system.

Proteomic profiling of exosomes: Current perspectives

The recent observation that exosomes contain both mRNA and microRNA, which can be transferred to another cell, and be functional in that new environment, is an exciting new development in the unraveling exosome saga.

Exosomes: composition, biogenesis and function

The physical properties that define exosomes as a specific population of secreted vesicles are described, their biological effects, particularly on the immune system, are summarized, and the potential roles that secretedvesicles could have as intercellular messengers are discussed.

Exosomes: A Bubble Ride for Prions?

Exosomes could constitute vehicles for transmission of the infectious prion protein, bypassing cell–cell contact in the dissemination of prionprotein, recent findings in non‐neuronal cell models indicate.
