Summary
Extracellular vesicles (EVs) show promise for diagnosing and treating aortic aneurysms (TAA and AAA). These EVs mediate key pathological processes and can be engineered for targeted therapies, offering new diagnostic and treatment strategies.
Area of Science:
- Vascular Biology and Nanomedicine
- Biomaterials and Drug Delivery
Background:
- Aortic aneurysms (TAA and AAA) are severe vascular diseases with high mortality and limited diagnostic/therapeutic options.
- Extracellular vesicles (EVs) are crucial intercellular communicators, gaining attention for their role in aneurysm development.
Purpose of the Study:
- To review research on EVs in thoracic and abdominal aortic aneurysms.
- To highlight EVs' role in aneurysm pathogenesis and their potential as diagnostic markers and therapeutic agents.
Main Methods:
- Systematic review of current research on extracellular vesicles in aortic aneurysm.
- Analysis of EV mediation in endothelial dysfunction, smooth muscle cell transformation, inflammation, and ECM remodeling.
- Evaluation of engineered EVs for targeted drug delivery and immunomodulatory therapies.
Main Results:
- EVs significantly contribute to the development and progression of aortic aneurysms.
- EVs carry disease-specific molecules, showing potential as liquid biopsy markers for early diagnosis.
- Engineered EVs offer promising therapeutic strategies, particularly cell-free immunomodulatory therapies targeting macrophages.
Conclusions:
- Extracellular vesicles hold significant potential for both early diagnosis and targeted treatment of aortic aneurysms.
- Engineering EVs with nanomedicine approaches can overcome challenges like targeted delivery, paving the way for integrated diagnostic and therapeutic strategies.
