Microbe-derived extracellular vesicles as a smart drug delivery system.

Area of Science:

• Microbiology
• Immunology
• Pharmacology

Background:

• The human microbiome significantly impacts host health.
• Extracellular vesicles (EVs) mediate intercellular communication and possess immunomodulatory effects.
• Microbiota-derived EVs are an emerging area of research with significant implications.

Purpose of the Study:

• To review the current understanding of microbiota-derived EVs.
• To explore their composition, biogenesis, and interaction with host cells.
• To discuss their pharmacological potential.

Main Methods:

• Literature review of existing research on microbiome-derived EVs.
• Analysis of EV biogenesis and composition.
• Examination of EV-host cell interactions and signaling pathways.

Main Results:

• Microbes secrete various EV classes (OMVs, MVs, apoptotic bodies).
• EVs are composed of lipids, proteins, nucleic acids, and potentially metabolites.
• These components are transferred to host cells, influencing cellular processes.

Conclusions:

• Microbiota-derived EVs play a critical role in host health.
• They hold promise as vaccine candidates, biomarkers, and drug delivery systems.
• Multidisciplinary research is needed to fully elucidate their mechanisms and applications.
