Image caption
Accessory Cells Are Activated by iRBCs PBMCs from ten malaria-naïve donors were cultured with live iRBCs or E. coli LPS for 24 h or left unstimulated. Surface expression of HLA-DR, CD40, and CD80 on accessory cells was analysed by flow cytometry. Accessory cells were defined as HLA-DR+ CD11c+ cells (A, left), and CD14+ monocytes and CD14− mDCs were selected for further analysis (A, right). Representative examples of surface expression levels of CD40, HLA-DR, and CD80 on HLA-DR+ CD11c+ CD14+ monocytes (B) and HLA-DR+ CD11c+ CD14− mDCs (C) are shown. Data are based on the collection of 100,000 total events. Results for all ten donors are summarised in (D). *, p <0.05; **, p <0.01; ***, p <0.001; p-values are for paired t tests comparing stimulated and unstimulated cells from the same donor.

Effect of rapamycin (Rapa) on the phenotype and function of H1-DC. DCs were either untreated, matured in response to the maturation cocktail or treated with Rapa for 3 days prior to maturation. (a) H1-DC stained for the expression of the maturation marker CD83, the costimulatory molecules CD86 and CD40, as well as the inhibitory receptor PD-L1. Dead cells were excluded from analysis using 7-AAD. Open histograms represent the level of background staining using appropriate isotype-matched controls. Data from one of 3 independent experiments are shown. (b) Phenotypic analysis of control populations of moDC treated and stained in parallel with rapamycin. (c) Effect of rapamycin on the allostimulatory capacity of DC in the allogeneic MLR. DCs were mitotically-inactivated using mitomycin C and plated in triplicate at a top dose of 104 cells per well of a 96-well round-bottomed plate; naïve CD4+ T cells were plated at 5 × 104 cells/well. Cells were incubated for 5 days before pulsing with 3H-thymidine overnight. Graphs show the mean of triplicate cultures ± S.D. Data are shown from one experiment, representative of 3 independent experiments.

LEF-M interferes with DC differentiation. (a) Monocytes were cultured for 5 days with granulocyte–macrophage colony-stimulating factor (GM-CSF; 50 ng/ml) plus IL-4 (10 ng/ml) in the absence or presence of 150 μmol/l of the active metabolite of leflunomide (LEF-M). Subsequently, surface marker expression was determined using fluorescence-activated cell sorting (FACS) analysis. Open profiles with dotted line represent staining pattern with an isotype control antibody, open profiles with fine line indicate the staining pattern of differentiated control dendritic cells (DCs) stained with the indicated mAbs, whereas solid grey profiles show staining of DCs differentiated in the presence of LEF-M. (b) Myeloid precursor cells differentiated in the presence of LEF-M are resistant to maturation. Cells were treated as described above and then stimulated with lipopolysaccharide (LPS; 100 ng/ml) for 48 hours. Open profiles with dotted line represent staining pattern with an isotype control antibody, open profiles with fine line indicate staining of activated control DCs, and solid grey profiles show staining of DCs differentiated in the presence of LEF-M and subsequently exposed to LPS. Data are representative of at least four independent experiments. (c,d) The effects of LEF-M on DC differentiation are independent of pyrimidine depletion. The respective change in mean flourescence intensity (MFI) are shown (c) after the differentiation phase for CD40 and CD1a and (d) after subsequent maturation with 100 ng/ml LPS for CD40 and CD83 with and without 50 μmol/l uridine. White bars represent control DCs, and black bars indicate LEF-M-treated cells. Shown are mean percentage control responses ± standard error of the mean, calculated from five to eight independent experiments. Student's t-tests were calculated for control versus LEF-M-treated DCs and for LEF-M-treated DCs versus without uridine addition, as indicated. *P <0.05, **P <0.01.

Treatment with LEF-M during maturation of immature DCs leads to a differentially affected phenotype. Monocytes were cultured for 5 days with granulocyte–macrophage colony-stimulating factor (GM-CSF; 50 ng/ml) plus IL-4 (10 ng/ml). (a) On day 5 these immature dendritic cells (DCs; 5 × 105/ml) were activated with lipopolysaccharide (LPS; 100 ng/ml) in the absence or presence of 150 μmol/l of the active metabolite of leflunomide (LEF-M) for 48 hours. Surface marker expression was determined by fluorescence-activated cell sorting analysis. Open profiles with dotted line represent the staining pattern with an isotype control, open profiles with fine line indicate the staining pattern of DC exposed to LPS with the indicated monoclonal antibodies, and solid grey profiles show staining of DCs matured in the presence of LEF-M. The results shown are representative of five independent experiments. (b,c) Effect of LEF-M on maturation-associated clustering of DCs; immature DCs were stimulated with LPS in the (panel b) absence or (panel c) presence of 150 μmol/l LEF-M. After 8 hours of cultivation, cells were analyzed by inspecting photomicrographs obtained by light microscopy. Similar results were obtained in four additional experiments. MHC, major histocompatibility complex.

DC differentiation from H1 hESC.
Cells were harvested from cultures at various time points and analysed by flow cytometry for the onset of hematopoiesis and the appearance of DC. (e) Phenotype of immature and mature H1-DCs compared with human moDC. DCs were cultured either in medium alone or medium supplemented with the maturation cocktail and stained for MHC class II, the maturation marker CD83 and classical costimulatory molecules. Dead cells were excluded from the analysis using 7-AAD. Dashed histograms show the phenotype of immature DCs while the filled histograms represent mature DCs. Open histograms depict background staining using isotype-matched controls.

Image caption:
Fig S2A: Among the PBMCs, a majority of the cells in the monocyte gate (60-70%) spontaneously expressed CD14, CD80, MHC II and CD40 at a high level but they did not express CD86
Fig S2B: After MACS selection, more than 90% of the cells were CD14+ and expressed CD80, MHC II and CD40 at a high level. Surprisingly approximately 30% of these cells also expressed CD86, suggesting that the positive selection process with the anti-CD14 antibody induced a cellular activation.
Fig 2C: After cMoDCs differentiation, the expression of CD14, CD80, MHC II and CD40 remained positive and high for a large majority of the cells (above 90%), while CD86 expression decreased under 10%.
