线粒体靶向抗氧化剂在雄激素性脱发治疗中的研究进展

    Research Progress of Mitochondria-targeted Antioxidants in the Treatment of Androgenetic Alopecia

    • 摘要: 雄激素性脱发(androgenetic alopecia,AGA)是全球高发的非瘢痕性脱发,现有治疗手段存在局限。线粒体功能障碍与氧化应激是该病发生发展的重要机制,线粒体靶向抗氧化剂也随之成AGA治疗的全新研究方向。本文梳理了二氢睾酮介导氧化应激、诱导线粒体损伤并造成毛囊微型化的分子机制,分类介绍了泛醌类、肽类、天然活性成分类线粒体靶向抗氧化剂的特性与应用场景,同时结合微针递送、外泌体载药、人工智能、基因编辑等前沿技术,分析了相关疗法的临床应用现状。最后展望了多靶点联合治疗、衰老细胞重编程、毛囊类器官模型构建等未来研究方向。本文全面综述了线粒体靶向抗氧化剂在AGA治疗中的作用机制、药物类型、技术应用及发展前景,为该领域后续基础研究与临床转化提供参考。

       

      Abstract: Androgenetic alopecia(AGA) is a highly prevalent non-scarring alopecia worldwide, and current treatments have certain limitations. Mitochondrial dysfunction and oxidative stress are vital mechanisms driving the progression of this disease, and mitochondria-targeted antioxidants have emerged as a novel research direction for its treatment. This paper elaborates on the molecular mechanism that dihydrotestosterone triggers oxidative stress and mitochondrial damage, ultimately leading to hair follicle miniaturization. It also introduces the characteristics and application scenarios of three major categories of mitochondria-targeted antioxidants including ubiquinone derivatives, peptide antioxidants and natural active ingredient. Combined with cutting-edge technologies such as microneedle delivery, exosome drug loading, artificial intelligence and gene editing, the clinical application status of related therapies is analyzed. Furthermore, the future research directions including multi-target combined therapy, senescent cell reprogramming and hair follicle organoid model establishment are prospected. This article comprehensively reviews the mechanism of action, drug categories, technical applications and development prospects of mitochondria-targeted antioxidants in the treatment of AGA, providing references for subsequent basic research and clinical transformation in this field.
