Overview of Exosomes

2.7K
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.
Stahl et al. discovered exosomes in 1983, but the exosomes were initially considered waste products released from the...

  • Nanotechnology

Background:

  • Extracellular vesicles (EVs) have been recognized for over 80 years, initially termed "'exosomes'.
  • Their biogenesis, release, and cargo (proteins, lipids, nucleic acids) are integral to intercellular communication.
  • EVs are implicated in physiological processes and various pathologies, including cancer and neurodegenerative diseases.

Discussion:

  • The heterogeneity of EVs necessitates standardized isolation and characterization methods.
  • Understanding EV surface markers and molecular cargo is key to deciphering their functional roles.
  • EVs represent a promising avenue for biomarker discovery and targeted drug delivery systems.

Key Insights:

  • EVs mediate complex biological signaling pathways.
  • Their cargo reflects the physiological state of the parent cell, making them valuable diagnostic biomarkers.
  • EVs can be engineered for therapeutic applications, enhancing drug delivery efficacy and specificity.

Outlook:

  • Further research into EV subtypes and their specific functions will refine their therapeutic potential.
  • Standardization of EV research protocols is essential for clinical translation.
  • The development of advanced EV-based diagnostics and therapeutics is anticipated to revolutionize personalized medicine.
