Article Title: Interferon-α and Interleukin-12 Are Induced Differentially by Toll-like Receptor 7 Ligands in Human Blood Dendritic Cell Subsets

doi: 10.1084/jem.20020207

Figure Lengend Snippet: TLR-7 ligands induce the production of IL-12 and IFN-α from MDCs and PDCs, respectively. (A and B) After 24-h culture with various stimuli, concentration of IL-12 p40+p70 (A) and IFN-α (B) in the culture supernatants of MDCs, PDCs, and PBMCs were measured by ELISA. The data are shown by means ± SEM of five independent experiments. (C) After 5-h culture with R-848 (10 −6 M), intracellular staining of IL-12 and IFN-α in MDCs and PDCs, together with the staining of surface expression of CD40, was performed. Percentages of the respective cytokine producing DCs are indicated. This figure represents the results from one of three experiments.

Article Snippet: 10 μg/ml brefeldin A (Sigma-Aldrich) was added during the last 1 h. After the stimulation, MDCs and PDCs were stained with Cy-Chrome-labeled CD40 (5C3; BD PharMingen), and then fixed, permeabilized (FIX and PERM kit; Caltag Laboratories), and stained with FITC-labeled anti–IL-12 p40+p70 mAb (B-P24; DIACLONE Research) or unconjugated mouse anti–human IFN-α mAb (MC-16; Genzyme).

Article Title: Monophosphoryl lipid A plus IFNγ maturation of dendritic cells induces antigen-specific CD8 + cytotoxic T cells with high cytolytic potential

Figure Lengend Snippet: The superior induction of CTLs by MPLA/IFNγ DCs compared to CC-DCs is dependent on IL-12 and not on IL-6 or IL-23. a Blocking antibodies specific for IL-12p40 and IL-6, and an irrelevant antibody were added to MPLA/IFNγ DC-CTL cocultures. 7 days after the second stimulation of the CTLs with DCs (day 17), the CTLs were stained with the MART-1 tetramer (TM) and CD8-FITC. A graph showing the % MART-1 TM cells for all separate cultures of one experiment is shown. The condition treated with anti-IL-12 significantly differed (one-way ANOVA, P < 0.05) from untreated or isotype control treated conditions. A representative experiment out of four is depicted. b Blocking antibodies specific for IL-12p35 and IL-23p19, and an irrelevant antibody were added to MPLA/IFNγ DC-CTL cocultures. 7 days after the third stimulation of the CTLs, the CTLs were stained with the MART-1 TM and CD8-FITC. A graph showing the % MART-1 TM cells for all separate cultures of one experiment is shown. The condition treated with anti-IL-12p35 significantly differed (one-way ANOVA, P < 0.01) from isotype control treated condition

Article Snippet: The following neutralizing antibodies were used; anti-IL-12p40 (C8.6), anti-IL-12p35 (B-T21, Diaclone), anti-IL-23p19 (B-Z23, Diaclone), anti-IL-6 (IL6.8 [ 26 ]).
