In the epidermal compartment of skin, keratinocytes (KC), Langerhans cells (LC), and their soluble products, i.e. cytokines, constitute a unique immunologic microenvironment. KC participate in cutaneous immune responses by producing various cytokines. LC, a member of the dendritic cell (DC) family, represent the professional antigen‐presenting cells in the epidermis. Although it has been demonstrated that migration of LC from skin to lymph nodes is a critical step for the antigen presentation, molecular mechanisms for such an event remain unclear. Recent studies suggest that cytokines are able to modulate LC/DC migration. There is accumulating evidence that proinflammatory cytokines including interleukin (IL)‐1 and tumor necrosis factor a promote LC emigration from the skin, whereas the anti‐inflammatory cytokine IL‐10 is a counter‐regulator. LC/DC express chemokine receptors. Chemokines generated from lymphatic endothelial cells and lymph node cells play a role in the directional migration of LC/DC into lymph nodes. This article reviews current studies on the role of cytokines in LC/DC migration. J. Leukoc. Biol. 66: 33–39; 1999.
