CyP specifically inhibits LPS stimulation of DCs. (A) DCs were stimulated for 16 h with different TLR agonists (1 μg/ml LPS, 10 μg/ml PGN, 20 μg/ml poly(I:C), and 2.5 μg/ml R848), 20 ng/ml IL-1β, or 1 μg/ml soluble CD40L in the absence or presence of 20 μg/ml CyP. Data are expressed as the percentage of the response (TNF production, black bars; IL-6 production, white bars) obtained with the specific agonists in the absence of CyP and represent the mean ± SD of four independent experiments. Inhibition of LPS was found to be statistically significant (P < 0.0001), whereas inhibition of all other stimuli was found to be nonsignificant (P > 0.05). (B) DCs were challenged with graded numbers of DH5α bacteria in the absence (white bars) or presence (black bars) of 20 μg/ml CyP. TNF was measured in the 20-h culture supernatants by ELISA. CyP did not affect bacterial growth. One representative experiment of three is shown. (C) DCs were stimulated with LPS, 10 ng/ml IFN-γ, soluble CD40L, or R848 alone or in the indicated combinations in the absence (white bars) or presence (black bars) of CyP. <t>IL-12p70</t> was measured in the 24-h culture supernatants.

(A) Cytokine concentrations assessed by Luminex®, values displayed represent the mean fluorescence intensity in pH1N1-infected/H3N2 infected conditions (MOI=3). Cytokines elevated by 2.5-fold over the level in mock-infected monocytes are plotted. (B) Impact of cytokine receptor blocking on the NK cell IFN-γ response evaluated by pre-incubating NK cells for 1 hr with blocking antibodies specific to IFNAR2, <t>IL-12R,</t> IL-15R, IL-18R, and IFNGR1 followed by co-culture with infected monocytes. 24 HPI, intracellular cytokine staining was used to assess NK cell IFN-γ + frequency compared to treatment with an isotype control antibody (H3N2: n =2-6, pH1N1: n =9). (C) NK cells were incubated for 1 hr with antibodies specific to IFNAR2 and CD226 or CD54 followed by co-culture with autologous infected monocytes. At 24 HPI, intracellular cytokine staining was used to assess IFN-γ production compared to treatment with an isotype control antibody ( n =6). * P < 0.05, ** P < 0.005, Wilcoxon signed-rank test. (D) Model of strain-specific NK cell recognition of influenza A infection. pH1N1-infection of monocytes virus does not downregulate CD54 and CD112 to the same extent as H3N2-infected monocytes. CD54 expression is retained on Flu-NP + cells while CD112 expression is preferentially retained on exposed, uninfected monocytes. pH1N1 infection of monocytes elicits enhanced IFN-α secretion and blockade of IFNAR2 dampens NK cell anti-pH1N1 IFN-γ production.

Figure 2. Production of interleukin-12 (IL-12) and IL-10 by lipopolysaccharide-stimulated peripheral blood mononuclear cells (PBMCs) of burn and trauma patients at serial intervals after injury. Thirty-eight observations of IL-10 production were made in 18 patients and 21 observations of IL-12 production in 8 of the same patients. PBMC IL-12 production was significantly diminished in the 8- to 14-day interval after injury when compared with simultaneously studied normal subjects. At the same interval, IL-10 production by the patients’ PBMCs was significantly elevated.

Burn mice receiving 5 ng interleukin-12 (IL-12) every other day for 9 days beginning on the day of injury had a survival similar to that of sham burn mice. IL-12 in a 10-ng dose appeared to have a less favorable effect on survival, and the addition of indomethacin to the 5-ng dose of IL-12 produced inferior results. IL-12 treatment did not affect the survival of sham burn mice.

CyP specifically inhibits LPS stimulation of DCs. (A) DCs were stimulated for 16 h with different TLR agonists (1 μg/ml LPS, 10 μg/ml PGN, 20 μg/ml poly(I:C), and 2.5 μg/ml R848), 20 ng/ml IL-1β, or 1 μg/ml soluble CD40L in the absence or presence of 20 μg/ml CyP. Data are expressed as the percentage of the response (TNF production, black bars; IL-6 production, white bars) obtained with the specific agonists in the absence of CyP and represent the mean ± SD of four independent experiments. Inhibition of LPS was found to be statistically significant (P < 0.0001), whereas inhibition of all other stimuli was found to be nonsignificant (P > 0.05). (B) DCs were challenged with graded numbers of DH5α bacteria in the absence (white bars) or presence (black bars) of 20 μg/ml CyP. TNF was measured in the 20-h culture supernatants by ELISA. CyP did not affect bacterial growth. One representative experiment of three is shown. (C) DCs were stimulated with LPS, 10 ng/ml IFN-γ, soluble CD40L, or R848 alone or in the indicated combinations in the absence (white bars) or presence (black bars) of CyP. IL-12p70 was measured in the 24-h culture supernatants. One representative experiment of four is shown.

Article Snippet: Cytokine production was measured in the supernatants of DCs (0.5 × 10 6 cells/ml) stimulated for 16–24 h using matched paired antibodies specific for human TNF, IL-6, and IL-12p70 (DuoSet ELISA development kits; R&D Systems).

(A) Cytokine concentrations assessed by Luminex®, values displayed represent the mean fluorescence intensity in pH1N1-infected/H3N2 infected conditions (MOI=3). Cytokines elevated by 2.5-fold over the level in mock-infected monocytes are plotted. (B) Impact of cytokine receptor blocking on the NK cell IFN-γ response evaluated by pre-incubating NK cells for 1 hr with blocking antibodies specific to IFNAR2, IL-12R, IL-15R, IL-18R, and IFNGR1 followed by co-culture with infected monocytes. 24 HPI, intracellular cytokine staining was used to assess NK cell IFN-γ + frequency compared to treatment with an isotype control antibody (H3N2: n =2-6, pH1N1: n =9). (C) NK cells were incubated for 1 hr with antibodies specific to IFNAR2 and CD226 or CD54 followed by co-culture with autologous infected monocytes. At 24 HPI, intracellular cytokine staining was used to assess IFN-γ production compared to treatment with an isotype control antibody ( n =6). * P < 0.05, ** P < 0.005, Wilcoxon signed-rank test. (D) Model of strain-specific NK cell recognition of influenza A infection. pH1N1-infection of monocytes virus does not downregulate CD54 and CD112 to the same extent as H3N2-infected monocytes. CD54 expression is retained on Flu-NP + cells while CD112 expression is preferentially retained on exposed, uninfected monocytes. pH1N1 infection of monocytes elicits enhanced IFN-α secretion and blockade of IFNAR2 dampens NK cell anti-pH1N1 IFN-γ production.
