[Extracellular vesicles in the central nervous system]

Area of Science:

• Neuroscience
• Cell Biology
• Biochemistry

Background:

• Extracellular Vesicles (EVs) are released by diverse cells, carrying proteins, RNAs, and lipids.
• EVs mediate intercellular communication, crucial in the complex nervous system network.
• They play significant roles in both physiological and pathological conditions.

Purpose of the Study:

• To review the diverse roles of EVs in a healthy brain.
• To discuss the involvement of EVs in nervous system development, synaptic transmission, and myelination.
• To address the pathological implications of EVs in neurodegenerative diseases, neuroinflammation, and tumor development.

Main Methods:

• Literature review of scientific publications on Extracellular Vesicles in the nervous system.
• Analysis of studies detailing EV functions in physiological and pathological brain states.
• Synthesis of current knowledge on EV-mediated intercellular communication.

Main Results:

• EVs are vital for maintaining cerebral homeostasis, supporting development, synaptic transmission, and axonal myelination in healthy brains.
• EVs are implicated in the spread of neurodegenerative diseases and contribute to neuroinflammation and tumor progression.
• Despite pathological roles, EVs may also offer therapeutic benefits in certain conditions.

Conclusions:

• Extracellular Vesicles are critical players in nervous system function and dysfunction.
• Understanding EV roles is essential for developing strategies against neurological disorders.
• EVs represent a significant area of research with potential therapeutic applications.
