Abstract:
Acute lung injury (ALI) is a severe and life-threatening condition characterized by inflammation, oxidative stress, and tissue damage. Despite advances in medical care, ALI remains a significant cause of morbidity and mortality. Mesenchymal stem cells (MSCs)-derived extracellular vesicles (EVs) have emerged as a promising therapeutic tool for ALI. This review aims to provide a comprehensive overview of the current understanding of MSCs-derived EVs in ALI, including their mechanisms, therapeutic potential, and future directions.
Introduction:
ALI is a complex and heterogeneous condition, involving various cellular and molecular mechanisms (1). The current treatment options for ALI are limited, and new therapeutic strategies are urgently needed (2). MSCs-derived EVs have shown promise in preclinical studies, demonstrating anti-inflammatory, antioxidant, and regenerative properties (3).
Mechanisms:
MSCs-derived EVs exert their therapeutic effects through various mechanisms, including:
1. Immune modulation: EVs can modulate the immune response, reducing inflammation and promoting tolerance (4).
2. Anti-inflammatory and antioxidant effects: EVs can reduce oxidative stress and inflammation, mitigating tissue damage (5).
3. Promotion of tissue repair and regeneration: EVs can enhance cellular survival, proliferation, and differentiation, promoting tissue repair (6).
4. Enhancement of cellular survival and proliferation: EVs can protect against cellular apoptosis and promote cellular growth (7).
Therapeutic Potential:
MSCs-derived EVs have been shown to:
1. Reduce inflammation and oxidative stress in preclinical models of ALI (8).
2. Improve lung function and histology in preclinical models of ALI (9).
3. Enhance survival in preclinical models of ALI (10).
Future Directions:
1. Large-scale clinical trials: Further clinical trials are needed to confirm the safety and efficacy of EV-based therapies (11).
2. Optimization of EV isolation and characterization methods: Standardized methods for EV isolation and characterization are needed (12).
3. Investigation of EV-mediated mechanisms: Further research is needed to understand the mechanisms underlying EV-mediated therapeutic effects (13).
4. Development of EV-based combination therapies: EVs may be combined with other therapies to enhance their therapeutic potential (14).
Conclusion:
MSCs-derived EVs hold promise as a therapeutic tool for ALI. Their anti-inflammatory, antioxidant, and regenerative properties make them an attractive candidate for treating this devastating condition. Further research is needed to fully understand their mechanisms and potential applications. With continued advancements, EV-based therapies may revolutionize the treatment of ALI and other respiratory diseases.
