3 Fig 2 Levels (mean ± SE) of the cytokines IL-4, IL-13, and IFN-γ in spleen cells from sensitized C3H/hej mice with saline (NS) or antigen (BSA or Lex-BSA) stimulated with NS, BSA, or Lex-BSA. N = 9 mice per group. ∗P < .05. Journal of Allergy and Clinical Immunology  , DOI: ( /j.jaci ) Copyright © 2007 American Academy of Allergy, Asthma & Immunology Terms and Conditions

7 Fig 6 Analysis of cytokines in BM-DCs. A and B, Levels (mean ± SE) of IL-12p70 (Fig 1, A) and IL-10 (Fig 1, B) in BALB/c BM-DCs are shown. DCs were incubated with medium alone or LPS in the presence or absence of varying concentrations of glycoforms as indicated, with their respective structures and linked positions for fucose shown. ∗P < .05 versus LPS alone. C, Levels (mean ± SE) of LPS-induced IL-12p70 and IL-10 production in BM-DCs. ∗P < .05 versus LPS alone. D, Mannan blocks the inhibitory effect of Lex-BSA on LPS-induced gene expression for IL-12p40 in BM-DCs. E, Relative level (mean ± SE) of nuclear NF-κB (nNF-κB) in BM-DCs. ∗P < .05. N = 3 experiments. Journal of Allergy and Clinical Immunology  , DOI: ( /j.jaci ) Copyright © 2007 American Academy of Allergy, Asthma & Immunology Terms and Conditions

8 Fig 7 Levels of antibodies and cytokines in IL-12−/− mice. A, Relative levels (mean ± SE) of serum BSA-specific antibodies. B, Levels (mean ± SE) of the TH2 cytokines IL-4 and IL-13 in spleen cells from BSA- or Lex-BSA–sensitized mice stimulated with BSA. N = 9 to 12 mice per group. ∗P < .05.
