An emerging interplay between extracellular vesicles and cytokines.

Area of Science:

• Cell Biology
• Immunology
• Biochemistry

Background:

• Extracellular vesicles (EVs) are vital for cell-to-cell communication.
• EVs transport proteins, lipids, and nucleic acids, influencing cellular functions.
• Cytokine secretion can occur via EVs, offering an alternative to classical pathways.

Purpose of the Study:

• To review cytokines and chemokines associated with EVs.
• To highlight the role of EVs in cytokine/chemokine secretion, trafficking, and content modulation.
• To focus on TNFα, IL-1β, and IFNs in the context of EVs.

Main Methods:

• Literature review of studies on EVs and cytokine/chemokine association.
• Analysis of proposed mechanisms for EV-mediated cytokine secretion.
• Focus on specific cytokines (TNFα, IL-1β, IFNs) and their EV interactions.

Main Results:

• EVs serve as significant carriers for cytokines and chemokines.
• Cytokine/chemokine association with EVs influences their release, trafficking, and content.
• TNFα, IL-1β, and IFNs are key examples of cytokines involved in EV-mediated communication.

Conclusions:

• EVs represent a crucial pathway for cytokine and chemokine secretion.
• Understanding EV-cytokine interactions is vital for comprehending intercellular communication in health and disease.
• Further research into EV-cytokine dynamics can reveal therapeutic targets.
