[Advances in the research of the relationship between skin regulatory T cells and wound healing and immune diseases].

As the body's largest organ, skin harbors a large amount of immune cells to regulate both innate and adaptive immune responses. Regulatory T cells (Tregs), as a subset of T lymphocytes with negative regulatory functions, play an important role in maintaining the immune homeostasis of different tissue. However, researches of skin Tregs are largely limited and uncompleted as compared with other tissue. In recent years, a comprehensive understanding is increasingly showing the specialized functions of Tregs in skin, including the orchestration of tissue wound healing, involvement in hair follicle recycling, and modulation of proper immune homeostasis. In this review, we outline the classification and characteristics of Tregs in skin, distribution, migration routes, immune effects, and relationship with wound healing, which aims to deepening our understanding towards the immunological effects of T lymphocytes subsets in skin and its regulatory pathways.作为机体最大的器官，皮肤中聚集了大量免疫细胞调节先天性和获得性免疫反应。调节性T细胞(Treg)作为具有负性调节功能的T淋巴细胞亚群，对维持不同组织免疫动态平衡发挥着重要作用。但是，相比于其他组织，有关Treg在皮肤组织中的研究相对较少，且不完善。近年来，随着研究的逐渐深入，研究者们认识到Treg在皮肤中具有特征性免疫效应，包括调控组织损伤修复、参与毛囊生长周期循环、诱导适当的免疫平衡等。本文就Treg在皮肤中的分类与特性、分布特点、迁移途径、免疫效应以及与创面愈合的关系进行综述，旨在深化对皮肤T淋巴细胞亚群免疫学效应及其调控途径的新认识。.
