Cells of the dendritic family display some unique properties that confer to them the capacity to sensitize naive T cells in vitro and in vivo. In the mouse, two subclasses of dendritic cells (DCs) have been described that differ by their CD8{alpha} expression and their localization in lymphoid organs. The physiologic function of both cell populations remains obscure. Studies conducted in vitro have suggested that CD8{alpha}+ DCs could play a role in the regulation of immune responses, whereas conventional CD8{alpha} DCs would be more stimulatory. We report here that both subclasses of DCs efficiently prime antigen-specific T cells in vivo, and direct the development of distinct T helper (Th) populations. Antigen-pulsed CD8{alpha}+ and CD8{alpha} DCs are separated after overnight culture in recombinant granulocyte/macrophage colony-stimulating factor and injected into the footpads of syngeneic mice. Administration of CD8{alpha} DCs induces a Th2-type response, whereas injection of CD8{alpha}+ DCs leads to Th1 differentiation. We further show that interleukin 12 plays a critical role in Th1 development by CD8{alpha}+ DCs. These findings suggest that the nature of the DC that presents the antigen to naive T cells may dictate the class selection of the adaptative immune response.

Key Words: primary response • T helper cell type 1/type 2 balance • interleukin 12 • tolerance • memory
