作为内脏和环境之间的保护性界面,皮肤会遇到大量的毒素、病原体和身体压力。为了对抗这些对皮肤微环境的攻击,皮肤的功能不仅仅是物理屏障:它是一个活跃的免疫器官。皮肤的免疫反应包括免疫活性细胞和包括细胞因子在内的可溶性生物反应调节剂。真皮被淋巴管和血管网络穿过,含有皮肤中的大部分淋巴细胞、其他迁移的白细胞、肥大细胞和组织巨噬细胞。虽然表皮不能直接进入血液或淋巴循环,但它配备了免疫活性细胞:朗格汉斯细胞,表皮的巨噬细胞样抗原呈递细胞;角质形成细胞,具有免疫特性的上皮细胞;树突状表皮T淋巴细胞,可作为原始T细胞免疫监视系统的驻留细胞;嗜表皮淋巴细胞,来自真皮血管的移行者;以及黑素细胞,具有免疫特性的表皮色素细胞。尽管表皮和真皮的成分协同作用在皮肤中执行免疫反应,但出于本综述的目的,我们将重点关注表皮免疫单位的细胞和细胞因子,这是针对环境毒素和微生物的免疫保护的前线。
As a protective interface between internal organs and the environment, the skin encounters a host of toxins, pathogenic organisms, and physical stresses. To combat these attacks on the cutaneous microenvironment, the skin functions as more than a physical barrier: it is an active immune organ. Immune responses in the skin involve an armamentarium of immune-competent cells and soluble biologic response modifiers including cytokines. Traversed by a network of lymphatic and blood vessels, the dermis contains most of the lymphocytes in the skin, other migrant leukocytes, mast cells, and tissue macrophages. Although the epidermis has no direct access to the blood or lymphatic circulation, it is equipped with immune-competent cells: Langerhans cells, the macrophage-like antigen-presenting cells of the epidermis; keratinocytes, epithelial cells with immune properties; dendritic epidermal T lymphocytes, resident cells that may serve as a primitive T-cell immune surveillance system; epidermotropic lymphocytes, migrants from vessels in the dermis; and melanocytes, epidermal pigment cells with immune properties. Although the components of the epidermis and dermis work in concert to execute immune responses in the skin, for purposes of this review, we focus on the cells and cytokines of the epidermal immunologic unit, the frontline of immune protection against environmental toxins and microbes.
