To elaborate on the dual role of extracellular vesicles (EVs) in the pathophysiology and treatment of atopic dermatitis (AD), emphasizing their complex interactions.
Key Findings:
EVs play a significant role in the pathogenesis of AD by delivering virulence factors and promoting immune dysregulation, highlighting their potential as therapeutic targets.
Therapeutic EVs show promise in modulating immune responses and restoring skin barrier function, suggesting a multifaceted approach to treatment.
Challenges include uneven source selection, lack of standardization, and insufficient mechanistic understanding, which must be addressed to advance the field.
Interpretation:
Future research should focus on standardizing protocols, enhancing mechanistic insights, particularly regarding immune interactions, and developing accurate disease models for EV-based therapies in AD.
Limitations:
Uneven source selection of EVs, affecting consistency.
Lack of standardization in preparation and characterization, leading to variability.
Insufficient mechanistic elucidation, hindering understanding of EV functions.
Limitations of preclinical models, which may not fully replicate human AD.
Inadequate pharmacokinetic and long-term safety data, necessitating further investigation.
Conclusion:
The review highlights the potential of EVs in addressing the complex pathophysiology of AD and emphasizes the need for further research to realize their therapeutic applications, particularly in developing standardized protocols and exploring innovative delivery methods.
