Extracellular vesicles degradation pathway based autophagy lysosome pathway

Area of Science:

• Cell Biology
• Molecular Biology

Background:

• The autophagy lysosome pathway is a fundamental cellular process for maintaining homeostasis by degrading damaged components.
• Extracellular vesicles (EVs), including exosomes and microparticles, are released by various mammalian cells and carry bioactive substances.
• EVs play significant roles in intercellular communication and biological functions.

Purpose of the Study:

• To review the molecular mechanisms underlying the interaction between extracellular vesicles and the autophagy lysosome pathway.
• To elucidate how extracellular vesicles are recognized and internalized by recipient cells.
• To describe the induction of autophagy by extracellular vesicles and its downstream effects.

Main Methods:

• Review of current literature on extracellular vesicle uptake and autophagy induction.
• Analysis of receptor-ligand interactions in extracellular vesicle recognition.
• Examination of how extracellular vesicles modulate autophagy-related pathways and molecules.

Main Results:

• Extracellular vesicles are identified and internalized by target cells via receptor-ligand interactions.
• Extracellular vesicles can induce intracellular autophagy pathways by delivering functional molecules or activating related pathways.
• EV-induced autophagy affects both the extracellular vesicles themselves and the recipient target cells.

Conclusions:

• Extracellular vesicle-mediated induction of autophagy is a key mechanism in cellular communication and homeostasis.
• Understanding this interaction provides insights into the biological functions of EVs.
• This review integrates knowledge on EV-induced autophagy, offering future research directions.
