摘要: 【摘要】 人们很早就注意到用皮肤磨削术、中医梅花针或皮肤微针,甚至剥脱性点阵CO2激光等对常规中波紫外线光疗抵抗的白癜风皮损可有效诱导复色。这些治疗除了因创伤增加药物透皮吸收外,还启动了创伤修复以及对毛囊或表皮黑素细胞的活化。伤口周围基底层角质形成细胞、血管内皮细胞和成纤维细胞分泌趋化因子12以招募毛囊隆突区或皮损周围表达趋化因子受体CXCR4/CXCR7的黑素细胞或黑素干细胞向白斑区移行。本文综述治疗性皮肤创伤诱导白癜风皮损复色的研究进展。

Abstract: 【Abstract】 It has long been noted that dermabrasion, plum-blossom needling or micro-needling, and even ablative fractional CO2 laser are effective for repigmentation of vitiligo lesions resistant to conventional ultraviolet B phototherapy. In addition to trauma-induced increase in the transdermal absorption of drugs, these treatments also initiate wound repair and activate melanocytes in hair follicles or epidermis. Basal layer keratinocytes, vascular endothelial cells and fibroblasts in the wound margins can secrete chemokine CXCL12 to recruit melanocytes or melanocyte stem cells expressing chemokine receptors CXCR4/CXCR7 in the hair follicle bulge or around the skin lesions to move towards the vitiliginous area. This review summarizes progress in repigmentation of vitiligo lesions induced by therapeutic skin trauma.
