Summary
Extracellular vesicles (EVs), including exosomes, are crucial cell communication tools. This review focuses on exosome secretion as a mechanism for cells to transfer materials for degradation, impacting cell physiology and disease pathogenesis.
Area of Science:
- Cell Biology
- Biochemistry
- Pathology
Background:
- Extracellular vesicles (EVs) encompass various cell-released vesicles, including exosomes and ectosomes.
- Distinguishing vesicle origin is vital as biogenesis relates to function and cell state.
- Current research often focuses on EV uptake effects, overlooking secretion mechanisms.
Purpose of the Study:
- To review exosome secretion as a process of material transfer from producing cells.
- To explore the role of exosomes in conveying cellular components for degradation by recipient cells.
- To understand the implications of exosome secretion in normal cell function and disease.
Main Methods:
- Literature review focusing on exosome biogenesis and secretion pathways.
- Analysis of studies examining the cargo and function of secreted exosomes.
- Synthesis of evidence linking exosome secretion to cellular homeostasis and pathogenesis.
Main Results:
- Exosomes function as a pathway for cells to export materials for extracellular degradation.
- This export can serve purposes like promoting differentiation and maintaining homeostasis.
- The exosomal pathway is implicated in the pathogenesis of numerous diseases.
Conclusions:
- Exosome secretion represents a fundamental cellular mechanism for material transport and regulation.
- Understanding exosome secretion is key to deciphering their role in health and disease.
- Further research into the exosomal pathway could reveal novel therapeutic targets.

Exocytosis
Exocytosis is used to release material from cells. Like other bulk transport mechanisms, exocytosis requires energy.
Intralumenal Vesicles and Multivesicular Bodies
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...
Recycling Endosomes and Transcytosis
The recycling endosome, also known as the endosomal recycling compartment (ERC), is a part of the slow-recycling process of the endocytic pathway. Molecules internalized through receptor-mediated endocytosis are either degraded in the lysosomes or are recycled to the plasma membrane through the fast- or slow-recycling route.
The recycling endosome is not a single organelle but an extensively tubulated network of recycling pathways. It functions in storing molecules or transporting them across...

Exocytosis
Exocytosis is a process that releases molecules outside the cell. Like other bulk transport mechanisms, exocytosis requires energy.
Exocytosis is the opposite of endocytosis, which brings molecules inside the cell. Sometimes, the released materials are signaling molecules. For example, neurons typically use exocytosis to release neurotransmitters. Cells also use exocytosis to insert proteins such as ion channels into their cell membranes, secrete proteins for use in the extracellular matrix, or...

Delivery Pathways to the Lysosome
Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.
Endocytosis
In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...

Overview of Exosomes
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.
