Summary
Sepsis involves complex immune changes. Extracellular vesicles (EVs) mediate these shifts, offering potential for diagnosing sepsis severity and developing personalized treatments for better patient outcomes.
Area of Science:
- Immunology
- Cell Biology
- Biochemistry
Background:
- Sepsis is a major global health threat characterized by complex immune dysregulation, not just inflammation.
- Existing treatments lack specificity due to significant patient variability and biological heterogeneity.
- Extracellular vesicles (EVs) are crucial for cell-to-cell communication and immune response modulation in sepsis.
Purpose of the Study:
- To review the role of extracellular vesicles (EVs) in mediating and reflecting immune heterogeneity in sepsis.
- To explore EVs as potential biomarkers for sepsis patient stratification and monitoring.
- To discuss the therapeutic potential of EVs in modulating immune responses and restoring homeostasis.
Main Methods:
- Literature review of experimental and clinical studies on EVs in sepsis.
- Analysis of current understanding of immune dysregulation in sepsis.
- Examination of EV-based diagnostic and therapeutic strategies.
Main Results:
- EVs are key mediators of intercellular communication in sepsis, influencing both inflammatory and immunosuppressive processes.
- EV molecular signatures correlate with sepsis severity, organ dysfunction, and patient prognosis, indicating biomarker potential.
- EVs can be engineered or derived from stem cells for therapeutic applications to modulate immune responses.
Conclusions:
- Extracellular vesicles (EVs) are central to understanding sepsis-induced immune heterogeneity.
- EVs offer a promising avenue for developing novel biomarkers for patient stratification and personalized immunotherapy in sepsis.
- Targeting or utilizing EVs could lead to more adaptive and individualized management strategies for sepsis patients.

Overview of Exosomes
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...

Human Virome
The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible only with...
