Advances in the research of the relationship between skin regulatory T cells and wound healing and immune diseases / 中华烧伤杂志

ABSTRACT

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.
