Abstract

Human plasmacytoid and myeloid dendritic cells (DCs), when appropriately stimulated, can express the archetypal natural killer (NK)-cell surface marker CD56. In addition to classical DC functions, CD56+ DCs are endowed with an unconventional cytotoxic capacity.

Keywords: CD56; cytotoxicity; dendritic cells; human; myeloid DCs; plasmacytoid DCs.

Figure 1. The killing road: postulated mechanism of action of killer dendritic cells. The killer dendritic cell (DC) recognizes (1) and kills (2) tumor cells. Tumor cell-derived fragments are then captured by the killer DC (3), internally processed (4) and subsequently presented on MHC molecules to CD4+ and CD8+ T cells (5). Tumor antigen-specific CD8+ CTLs then lyse the remainder bulk of tumor cells (6).
