Dendritic cells (DC) were originally found critical in the setting of cognate immune responses. We first demonstrated that DC can also induce mouse NK cell activation and NK cell dependent-antitumor effects in mice. Here we analyzed the dynamics between DC and NK cells in human in vitro model systems. In the absence of LPS, DC do not trigger resting NK cells. Conversely, in the presence of LPS, resting bulk NK cells interacting with DC acquire CD25 and CD69 surface expression, produce high levels of IFN-gamma and lyse DAUDI cells. On activated IL-2 dependent NK cell lines, regardless of their differentiation stage, DC maintain or enhance NK cell proliferation and effector functions in the absence of exogenous cytokines. While IL-12, IL-15 and IL-18 are not critical, a direct cell-to-cell contact is mandatory for NK activation by DC and required for optimal proliferation. These data imply that DC also modulate human NK cell innate effector functions.
