Advanced Drug Delivery Reviews
|March 11, 2020
Summary
Extracellular vesicles (EVs) are cell-derived nanoparticles with a lipid bilayer. This review highlights the growing importance of understanding EV lipid composition and function for disease biomarkers and drug delivery applications.
Area of Science:
- Biochemistry
- Cell Biology
- Nanotechnology
Background:
- Extracellular vesicles (EVs) are lipid bilayer-enclosed nanoparticles released by cells.
- They protect encapsulated biomolecules (proteins, nucleic acids, lipids) from the environment.
- EVs are investigated as disease biomarkers, drug delivery vehicles, and tools for studying cell trafficking.
Purpose of the Study:
- To review the current understanding of lipid composition in extracellular vesicles.
- To highlight the functional roles of lipids within EVs.
- To identify future research directions for advancing the field of EV lipidomics.
Main Methods:
- Literature review of current research on extracellular vesicle lipids.
- Analysis of studies investigating EV biogenesis and lipid function.
- Synthesis of findings to outline the current state of knowledge.
Main Results:
- Lipids are crucial components of the EV lipid bilayer membrane.
- Knowledge regarding specific lipid composition and functional roles in EVs is currently limited.
- There is increasing research interest in EV lipids and their significance.
Conclusions:
- Further research into EV lipidomics is essential.
- Understanding lipid composition will enhance EV applications in diagnostics and therapeutics.
- This field requires focused investigation to unlock the full potential of extracellular vesicles.

01:36Overview of Exosomes
3.4K
Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.

01:38Intralumenal Vesicles and Multivesicular Bodies
4.6K
Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...

Biological membranes are more than just a barrier separating cell cytoplasm from the outside environment. They are highly dynamic and help maintain the integrity and physiological stability of the cells as well as membrane-bound organelles. Membranes also play vital roles in cell-to-cell and intracellular communication.

01:35Asymmetric Lipid Bilayer
9.4K
Biological membranes show uneven distribution of different types of lipids in the inner and outer layers, resulting in transverse asymmetric membranes. The treatment of the erythrocyte membrane with the enzyme phospholipase confirmed the asymmetric nature of the lipid bilayer. The enzyme hydrolyzes lipids into fatty acids and hydrophilic groups. The phospholipase acts only on the outer layer of the membrane, while the inner layer remains intact. The phospholipase treatment resulted in 80%...

Lipids are an essential component of all biological membranes. The average lipid content in mammalian membranes is 50%, though it can be as low as 20% in the inner mitochondrial membrane or as high as 80% in the myelin sheath present around the nerve cells.
Phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, and sphingomyelin are the most common phospholipids present in mammalian membranes. At physiological pH, phosphatidylserine is negatively charged, while the other three...

6.9K
The membrane domains concentrate specific lipids and proteins at one place within the membrane, which helps in cell signaling, adhesion, and other critical cellular processes. These domains can differ in size, composition, function, and lifespan.
Protein Domains
The membrane comprises a group of distinct proteins responsible for carrying out a cell's specific function. For example, the plasma membrane of the human sperm, or a single germ cell, contains a unique set of proteins in the...
