Differential control of Th2 and Th17 cytokine production by EC and DC expression of Myd88 (a,b) Cytokines in mLNs after a single sensitization (a) or two sensitizations (b) with 100 μg OVA and 1.25 μg FLA. (c) T-cell proliferation and cytokine production in co-cultures of OT-II T cells mixed with the indicated APC(s) sorted from lungs of mice 6 h after sensitization with OVA/FLA. (d) Intracellular staining for IL-17 and type 2 cytokines in CD4+ T cells of mice sensitized with OVA/FLA o.p. on days 0 and 7 and collected on day 10. Lung cells were stimulated with Phorbol 12-myristate 13-acetate (PMA) and ionomycin prior to staining. Data shown are (a) representative of two experiments with 8–10 mice per group; (b) from a single experiment, representative of two, 4–5 mice per group; (c) representative of a single experiment performed with duplicate samples; and (d) from a single experiment with 3–4 mice per genotype. *P<0.05, **P<0.01, ***P<0.001, ****P<0.0001. APC, antigen presenting cell; DC, dendritic cells; EC, epithelial cells; FLA, flagellin; IL, interleukin; mLN, mediastinal lymph node; o.p., oropharyngeal; OVA, ovalbumin.
