Overview of Exosomes

2.9K
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...

Area of Science:

  • Cell Biology
  • Biochemistry
  • Endocrinology

Background:

  • Exosomes are nano-sized extracellular vesicles facilitating intercellular communication.
  • Adipose tissue-derived exosomes (AT-Exosomes) are increasingly recognized for their roles in physiological and pathological processes.
  • These vesicles contain diverse biomolecules, including non-coding RNAs, mRNAs, and proteins.

Purpose of the Study:

  • To review the isolation and identification methods for exosomes, specifically AT-Exosomes.
  • To categorize and summarize the components and biological functions of mammalian exosomes.
  • To elaborate on the physiological and pathological roles of AT-Exosomes in adipose tissue and other organs.

Main Methods:

  • Literature review and synthesis of existing studies on AT-Exosomes.
  • Categorization of AT-Exosome research based on their functions.
  • Analysis of AT-Exosome components and their impact on cellular and tissue functions.

Main Results:

  • AT-Exosomes regulate metabolic homeostasis in organs like the liver and skeletal muscle.
  • They are implicated in both the treatment and progression of various diseases.
  • Detailed discussion on AT-Exosome crosstalk within adipose tissue and their systemic effects.

Conclusions:

  • AT-Exosomes are crucial signaling mediators with significant physiological and pathological implications.
  • Further research is needed to fully elucidate the potential and challenges in AT-Exosome studies.
  • Future directions include exploring novel therapeutic applications and understanding complex regulatory mechanisms.
