Interleukin 12 (IL-12) is an important cytokine produced by a variety of immune effector cells that leads to a type 1 helper T cell (Th1) response. IL-12 also directs T cells to the skin via induction of cutaneous lymphocyte antigen (CLA) expression. In this article we report the current understanding of the immunobiology of IL-12, reviewing its structure, receptor, and function. We also discuss the role of IL-12 in the pathogenesis of psoriasis. Some effective conventional psoriasis treatments alter IL-12 levels. Importantly, specific antibodies directed against IL-12 may prove useful against psoriasis but may also act by targeting IL-23 in addition to IL-12.
