Effects of adsorption of LPS onto OVA/TT/alum sensitization on OVA-induced airway allergic inflammation. (a) Protocol: BALB/c mice sensitized with s.c. OVA/TT/alum in the presence or not of LPS (10 μg) on days 0 and 7 and challenged with i.n. OVA on days 14 and 21. Samples obtained on day 22. (b) Total number of cells and (c) eosinophils in BAL: ((d) and (e)) levels of IL-5 and IFN-γ in BAL. Data shown as mean ± SE, one-way ANOVA: #; different from OVA/TT/alum/PBS group (), and experiment was repeated twice.
