CD4+ or CD8+ T-cell depleted PBMC or unseparated PBMC of Donor 1 were tested in an IFN-γ ImmunoSpot® assay. The numbers of I-HCMV or HCMVpp65-induced IFN-γ SFU were measured for each condition, and the mean and SD for three replicate measurements of each are shown. ( B ) PBMC cell-number dependence of SFU. PBMC of Donor 1 were plated in the specified cell numbers per well and I-HCMV or HCMVpp65 (specified by color) was added at 50 μg/mL or 1 μg/mL, respectively. The numbers of IFN-γ SFU were established. Means and SD are shown for triplicate wells. The result of regression analysis for the experimental data approaching linearity is specified for both conditions as the R 2 value in color. ( C ) Establishing the optimal antigen dose for stimulation of HCMV-specific T cells by HCMVpp65 peptides. PBMC of Donor 1 were plated at 3 × 10 5 cells per well along with the different peptide concentrations specified. The number of IFN-γ SFU was measured in single wells. ( D ) Establishing the optimal antigen dose for stimulation of HCMV-specific T cells by I-HCMV. PBMC of Donor 1 were plated at 3 × 10 5 cells per well along with the different antigen concentrations specified. The number of IFN-γ SFU was measured in single wells.

A , NK cells cultured in the conditions above were incubated with K562 cells at the indicated effector:target ratios followed by the addition of Caspase-3/7 Green Detection Reagent. FACS was used to determine the percentage of K562 cells undergoing apoptosis ( n = 15). Results are from 3 independent experiments and are shown as mean ± SEM. Paired Student’s t tests were used for statistical analyses. * p ≤ 0.05, ** p ≤ 0.01. NK cells cultured in the conditions above were incubated with K562 cells at a 1:1 ratio, and intracellular FACS was used to measure the percentage of CD3 − CD56 + NK cells positive for B , TNF and C , IFN-γ (right panel) ( n = 7). Results are from 4 independent experiments and are shown as mean ± SEM. Paired Student’s t tests were used for statistical analyses. * p ≤ 0.05, ** p ≤ 0.01. NK cells ( n = 3) cultured in the conditions above were incubated with D , A549 cells, E , SKOV-3 cells and F , PANC-1 cells expressing NucLight Red fluorescent protein at a 3:1 ratio with the addition of a control anti-CD20 antibody. Parallel assays with NK cells ( n = 3) cultured in the conditions above were performed with G , A549 cells, H, SKOV-3 cells and I, PANC-1 cells expressing NucLight Red fluorescent protein at a 3:1 ratio with the addition of either anti-Her2 or anti-EGFR antibodies. An IncuCyte Imaging System was used to measure target cell killing over 48 hours. Results are from 3 independent experiments and are shown as mean ± SEM. Two-way ANOVA with Tukey’s multiple comparisons tests was used to determine significance.

    HIV transfer assay mediated by DC-SIGN . Cell surface DC-SIGN expressing HEK (DC-HEK) cells were grown in a 12-well plate to form a confluent layer. Different concentrations of proteins were added to the cells and incubated for 2 h for binding. Unbound proteins were removed and cells were challenged with 2.5 ng/mL p24 of HIV-1 (SF-162 strain) for 1 h. Unbound virus was washed off and cells were co-cultured with PHA-activated PBMCs for 24 h. PBMCs were separated from the DC-HEK monolayer and cultured separately for 7 days to determine viral titer of the supernatants collected on days 4 and 7.

    Comparison of differentially expressed gene lists across experimental groups. Microarray analysis was used to identify differentially expressed genes in PPD-stimulated PBMCs isolated at 6 weeks post-challenge with M. tuberculosis from vaccinated controllers (n = 6), unvaccinated controllers (n = 3) and unvaccinated progressors (n = 3) compared with expression when animals were naïve. Key genes of interest in each list are indicated. Underlined genes were down-regulated in expression from naïve time-points.
