Extracellular vesicles (EVs) are emerging as key players in cardiac amyloidosis, mediating disease spread and remodeling. Research highlights their potential as diagnostic markers and therapeutic targets for this infiltrative cardiomyopathy.
Area of Science:
- Cardiology
- Biochemistry
- Cell Biology
Background:
- Cardiac amyloidosis involves protein misfolding and extracellular deposition in the heart.
- Immunoglobulin light chains (AL) and transthyretin (ATTR) are the most common causes.
- Extracellular vesicles (EVs) are increasingly recognized for their role in disease progression.
Purpose of the Study:
- To synthesize emerging data on the role of EVs in cardiac amyloidosis.
- To review EVs as mediators of amyloid propagation, inflammation, and myocardial remodeling.
- To explore the diagnostic and therapeutic potential of EVs in cardiac amyloidosis management.
Main Methods:
- Structured narrative review of literature from PubMed and Scopus (2020-2025).
- Adherence to Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines.
- Synthesis of experimental and preclinical data on EV function and therapeutic applications.
Main Results:
- EVs serve as scaffolds for protein aggregation (transthyretin, serum amyloid A) and transport disease-specific cargo.
- EV-mediated serum amyloid A transport can occur under cardiac stress.
- Stem-cell-derived EVs show regenerative and anti-fibrotic effects in preclinical models.
Conclusions:
- EVs are implicated in the pathogenesis and progression of cardiac amyloidosis.
- EVs hold promise as diagnostic biomarkers and therapeutic agents.
- Further research and clinical trials are needed to overcome challenges and realize the full potential of EV-based therapies.
