Exosomes and Exosome-Mimetics for Atopic Dermatitis Therapy

Background:Exosomes and exosome mimetics are used as alternatives to cell therapy. They have shown potential in treating skin disorders by fortifying the skin barrier, mediating angiogenesis, and regulating the immune response while minimizing side effects. Currently, numerous studies have applied exosome therapy to treat atopic dermatitis (AD) caused by a weakened skin barrier and chronic inflammation. Research on exosomes and exosome mimetics represents a promising avenue for tissue regeneration, potentially paving the way for new therapeutic options. However, the efficacy of the therapy remains poorly understood. Also, the potential of exosome mimetics as alternatives to exosomes in skin therapy remains underexplored.Methods:Here, we reviewed the pathological features and current therapies of AD. Next, we reviewed the application of exosomes and exosome mimetics in regenerative medicine. Finally, we highlighted the therapeutic effects of exosomes based on their cell source and assessed whether exosome mimetics are viable alternatives.Results and conclusion:Exosome therapy may treat AD due to its skin regenerative properties, and exosome mimetics may offer an equally effective yet more efficient alternative. Research on exosomes and exosome mimetics represents a promising avenue for tissue regeneration, potentially paving the way for new therapeutic options.
