    Thermo Fisher interferon γ ifn γ
    Thy-1 cross-linking boosts α-galactosylceramide (αGC)-mediated cytokine secretion by primary mouse natural killer (NKT) cells. Hepatic lymphoid mononuclear cells were stained with a FITC-conjugated anti-T-cell receptor-β (TCR β) mAb, a phycoerythrin-conjugated anti-NK1.1 monoclonal antibody and either PBS-57-loaded or -unloaded CD1d tetramer (labelled with allophycocyanin). TCR-β + NK1.1 + cells were gated on (a; left panels) and assessed for their reactivity with CD1d tetramer reagents (a; right panels). Highly pure TCR β + NK1.1 + hepatic NKT cells were sorted and co-cultured with bone marrow-derived dendritic cells at a ratio of five i NKT cells to one bone marrow-derived dendritic cell. Cells were incubated with αGC alone (100 ng/ml), a low (5 μg/ml) or high (40 μg/ml) dose of G7, or a combination αGC and G7. After 48 hr, culture supernatants were harvested and <t>interferon-γ</t> <t>(IFN-γ)</t> levels (b) and interleukin-4 (IL-4) levels (c) were measured by ELISA. Statistical significance is denoted by asterisks, where ** and *** represent P

    The effect of mycophenolic acid (MPA), cyclosporine A (CsA), or intravenous immunoglobulin (IVIg) on endothelial cell (EC)-mediated allogeneic CD4 + -T cell polarization is maintained when PBMC have been exposed to immunosuppressors or IVIg. Figure shows the proportion of interleukin-17 producing cells [ (A) , n > 5 donors], interferon γ <t>(IFN-γ)</t> producing cells [ (B) , n > 5 donors], T memory cells [ (C) , n > 6 donors], and their proliferation [ (D) , n > 6 donors], Treg [ (E) , n > 6 donors], and Treg proliferation [ (F) , n > 6 donors]. Like ECs, PBMC were pretreated with MPA, CSA, or IVIg prior to coculture. In all conditions, PBMC and ECs were treated with the same immunomodulators. The concentrations used for stimulation of ECs and PBMC were 3 µg/ml for MPA, 5 µg/ml for CsA, and 1 mg/ml for IVIg. Results are expressed as the relative percentage of the control values corresponding to ECs treated with vehicle and PBMC treated by immunomodulators (represented by dotted lines). In all figures, horizontal lines show median values (* p

    Increased cytokine production in Nur77- and Nurr1-transduced FBMSC does not influence T-cell proliferation. (A) Four days after transduction, IL-6 and IL-8 protein secreted in supernatant of unstimulated FBMSC cultures were measured by ELISA after 24 h incubation and mRNA levels of HGF , TGF-β1 , and IDO were analyzed by RQ-PCR. Basal protein levels of IL-6 and IL-8 and HGF mRNA expression were significantly increased in Nur77- or Nurr1-transduced FBMSC compared with mock-transduced FBMSC. Data (mean±SD) normalized to unstimulated mock-transduced MSC. (B) Transduced FBMSC were stimulated with TNF-α and <t>IFN-γ</t> for 24 h or left untreated. Again the highest levels of IL-6 and IL-8 protein and HGF mRNA were observed in Nur77- and Nurr1-tranduced FBMSC. Data (mean±SD) normalized to unstimulated mock-transduced MSC. (C, D) Transduced FBMSC were cocultured with CD3/CD28 bead-activated PBMC. FBMSC with enhanced expression of Nur77 (C) or Nurr1 (D) have at least a similar capacity to inhibit T-cell proliferation compared with mock-transduced FBMSC. Beads were added to PBMC as negative control (CCPM count 49.157). Data represent pooled data (mean±SD) of 3 individual FBMSC donors cocultured with the same allogeneic PBMC.

    Patient 1. (A) Effect of intermittent interruptions of antiretroviral therapy on viral load and CD4 or CD8 counts. The HIV-1 RNA level was measured by RT-PCR with a limit of sensitivity of 20 copies per ml. Viral loads are expressed as numbers of HIV-1 RNA copies per milliliter of plasma; CD4 and CD8 counts were analyzed by flow cytometry with fluorescent beads as an internal standard. The values (mean ± standard deviation) in healthy people are as follows: CD4 + cells, 858 ± 260 cells/μl of plasma; CD8 + cells, 482 ± 164/μl plasma. White areas at top of the figure indicate periods of treatment (nevirapine, stavudine, and lamivudine); interruptions are in grey and are also shown in panels A to D. (B) Effect of intermittent interruptions of antiretroviral therapy on Ki67 antigen expression. Ki67 antigen expression was analyzed in CD4 + and CD8 + T cells by flow cytometry after intracellular staining. The values in healthy people are 2.5% ± 0.6% for CD4 + Ki67 + cells and 2% ± 0.6% for CD8 + Ki67 + cells. (C) Effect of intermittent interruptions of antiretroviral therapy on T-helper cell responses to HIV-1 p24 protein. HIV-1 p24-stimulated IFN-γ production by CD8-depleted PBMC was measured by enzyme-linked immunosorbent assay in the 2-day culture supernatants and is expressed as 10 −1 picograms per milliliter; T cell proliferative responses against HIV-1 (p24) were measured on CD8-depleted PBMC, and the results are expressed as a stimulation index. (D) Effect of intermittent interruptions of antiretroviral therapy on CD8 + cell responses to HIV-1 protein.
