由于黑色素合成过程中产生的促氧化状态,以及在病理条件下受损的内在抗氧化防御,表皮黑色素细胞特别容易受到氧化应激的影响。黑色素瘤被认为是氧化应激驱动的,白癜风中的黑素细胞死亡被认为是由表皮高度促氧化状态引起的。我们回顾了目前关于黑色素和黑素细胞氧化还原状态的知识,旁分泌因子如何帮助抵消氧化应激,氧化应激在白癜风中黑色素瘤的发生和进展以及黑素细胞死亡中的作用,以及如何利用这些知识治疗黑色素瘤和白癜风。
Epidermal melanocytes are particularly vulnerable to oxidative stress due to the pro-oxidant state generated during melanin synthesis, and to intrinsic antioxidant defences that are compromised in pathologic conditions. Melanoma is thought to be oxidative stress-driven, and melanocyte death in vitiligo is thought to be instigated by a highly pro-oxidant state in the epidermis. We review the current knowledge about melanin and the redox state of melanocytes, how paracrine factors help counteract oxidative stress, the role of oxidative stress in melanoma initiation and progression and in melanocyte death in vitiligo, and how this knowledge can be harnessed for melanoma and vitiligo treatment.
