DCs from WT CBA and CBA IL-12p40−/−mice (two mice per group) were cultured with eggs or control LPS for 24h, and culture supernatants were assayed for (a) IL-12p40, (b) IL-6 (c) TNF-α, (d) TGF-βand (e) IL-10 by ELISA. Cytokine levels are expressed as means of triplicate ELISA determinations ± SD; where appropriate, background cytokine levels from unstimulated controls were subtracted;nd, not detectable. Data are from one representative experiment of three.
