The Langerhans cell is a dendritic cell within the epidermis, which shows itself as the outer guardian of the immunological system. The cell stretches dendrites between the keratinocytes, makes a spiderweblike antigen snare, and thus plays the part of a highly specialized macrophage within the epidermal tissue. The development of new identification methods has made it possible to study the functions of the Langerhans cell in allergic contact dermatitis. The roll this cell plays in the pathogenesis of other dermatoses is still unclear, however.
朗格汉斯细胞是表皮内的一种树突状细胞，它是免疫系统的外部守护者。该细胞在角质形成细胞之间伸展树突，形成蛛网状的抗原陷阱，从而在表皮组织中扮演高度特化巨噬细胞的角色。新鉴定方法的发展使研究朗格汉斯细胞在过敏性接触性皮炎中的功能成为可能。然而，该细胞在其他皮肤病发病机制中所起的作用仍不清楚。
