Summary
Cell-specific exosomes offer a novel liquid biopsy approach for understanding sepsis-induced acute respiratory distress syndrome (ARDS). These exosomes reveal complex intercellular communication, paving the way for precise ARDS subtyping and targeted therapies.
Area of Science:
- Biomedical Science
- Molecular Biology
- Cellular Communication
Background:
- Sepsis-induced acute respiratory distress syndrome (ARDS) exhibits significant clinical heterogeneity, making traditional biomarkers inadequate for lung-specific pathology.
- Cell-specific exosomes are stable, reflect parent cell molecular signatures, and show promise as liquid biopsy tools.
Purpose of the Study:
- To elucidate the role of exosomes in intercellular communication within the alveolar-capillary barrier in ARDS.
- To analyze exosome-mediated propagation of ferroptosis, mitochondrial damage, immunometabolic reprogramming, and vascular dysfunction.
- To propose a precision medicine framework for ARDS subphenotyping using exosomal molecular fingerprints.
Main Methods:
- Review of current literature on exosome biology and ARDS pathogenesis.
- Analysis of exosome-mediated mechanisms including ferroptosis, mitochondrial damage, glycolysis, histone lactylation, vascular leakage, and immunothrombosis.
- Integration of single-cell omics advancements and technical barrier assessment.
Main Results:
- Alveolar epithelial exosomes propagate ferroptosis and mitochondrial damage.
- Macrophage exosomes drive immunometabolic reprogramming via glycolysis and histone lactylation.
- Endothelial exosomes contribute to vascular leakage and immunothrombosis, potentially mediating cuproptosis.
Conclusions:
- Exosomes play a critical role in the multidimensional communication network within the compromised alveolar-capillary barrier during ARDS.
- A precision medicine framework utilizing exosomal molecular fingerprints can enable ARDS subphenotyping.
- This approach could shift ARDS clinical practice towards mechanism-driven theranostics.
