Intracellular GM-CSF staining on CD56+ cells from hPBMC. (A) In the presence of the indicated ODN plus IL2: GM-CSF content in the cell culture without ODN stimulation was used as a control. Data are shown as mean +SD and are representative of three similar experiments. A specific response was defined as a response where the percentage of GM-CSF in CD56+ lymphocytes was at least 2-fold below the background observed in the medium control. The asterisk indicates statistically significant differences (p<0.05). (B) In the presence of IL2 in both CD3+ (NKT) and CD3- (NK) CD56+ dim or bright populations: ODNs and/or IL2 were added to the medium to reach a final concentration of 6 μg/ml and 400 IU/ml respectively. Dot plots are representative of three similar experiments.

NK Cells Do Not Respond to iRBCs in the Absence of Accessory Cells PBMCs or MACS-purified NK cells from malaria-naïve donors were cultured alone or with IL-12 and IL-18, uRBCs, or live iRBCs for 24 h. Intracellular IFN-γ and surface expression of CD69 on CD3− CD56+ NK cells were analysed by flow cytometry. (A and B) Representative example of NK responses to uRBCs, IL-12 and IL-18, and iRBCs in PBMCs (A) and purified NK cells (B). FACS plots are gated on CD3− CD56+ lymphocytes. Percentages indicate the proportion of CD3− CD56+ NK cells in each gate; data are based on the collection of 100,000 total events. (C and D) Comparison of NK responses to iRBCs in PBMCs and in purified NK cells. (C) NK cell IFN-γ production for six donors. (D) CD69 surface expression levels for seven donors. **, p <0.01; ***, p <0.001; p-values are for paired t tests comparing stimulated and unstimulated NK cells from the same donor, or PBMCs and pure NK cells from the same donor. (E) MACS-purified, CTG-labelled NK cells were added to autologous PBMCs. IFN-γ production in CTG+ (MACS-purified) and CTG− (“untouched”) NK cells was assessed by flow cytometry after 24 h of stimulation with iRBCs. A representative example of the software gating strategy to analyse IFN-γ responses of CTG-labelled NK cells is shown. FACS plots were gated on CD3− CD56+ NK cells within the lymphocyte population (first panel), and NK cells were analysed for CTG staining (second panel). CTG+ CD3− CD56+ NK cells (third panel) or CTG− CD3− CD56+ NK cells (fourth panel) were selected and analysed for intracellular IFN-γ production. Numbers indicate the proportion of IFN-γ+ NK cells.

HLA-DR+ Accessory Cells Provide Activating Signals to NK Cells PBMCs from malaria-naïve donors were depleted of different populations of accessory cells, and NK cell responses to iRBCs were analysed after 24 h of co-culture. (A) Representative example of NK cell IFN-γ responses in undepleted PBMCs (top left), PBMCs depleted of all HLA-DR+ antigen-presenting cells (APC) (top right), CD14+ monocyte–depleted PBMCs (middle left), CD19+ B cell–depleted PBMCs (middle right), CD1c+ mDC–depleted PBMCs (bottom left), and BDCA-4+ pDC–depleted PBMCs (bottom right). FACS plots are gated on CD3− CD56+ lymphocytes. Percentages indicate the proportion of CD3− CD56+ NK cells that were positive for IFN-γ; data are based on the collection of 100,000 total events. (B) NK cell IFN-γ production after depletion of different antigen-presenting cell populations. Percentage of IFN-γ NK cells relative to the response in undepleted PBMCs is shown; each spot represents data for a different donor. *, p < 0.05; ***, p < 0.0001; p–values are for paired t tests of the difference between depleted and undepleted cells:
