Cell differentiation was made by flow cytometric analysis as described earlier [12]. Lung-draining lymph node cell suspensions were restimulated for 4?days with 10?��g/ml OVA (Worthington, Lakewood, NJ, USA) or 100?��g/ml HDM extract. Supernatants were analysed for IL-4, IL-5, IL-13 and IFN�� production by ELISA (Ready-set-go!, [https://en.wikipedia.org/wiki/Dipivefrine Dipivefrine] eBioscience Inc, San Diego, CA, USA). Serum was analysed for the level of OVA-specific IgE by ELISA (Opteia; BD, San Diego, CA, USA). A standard curve of murine IgE was used as a quantitative reference. Frozen sections (6?��m) were stained with periodic acid Schiff's reagent (Sigma-Aldrich). Degree of inflammation and mucus-producing goblet cells were semi-quantified as described earlier [7]. Lungs of HDM-sensitized and challenged mice and PBS control [http://www.selleckchem.com/products/cx-5461.html CX-5461 chemical structure] mice were digested as described earlier [7]. DCs were identified as CD11chi, MHCIIhi, CD11bhi, CD19/CD3/B220/CCR3neg, and the expression of CD80, CD86 and CD40 was determined by flow cytometric analysis as described earlier [7]. For statistical analysis, Kruskal�CWallis one-way anova and the Mann�CWhitney U-test were performed using PASW statistics. All experiments were performed 2�C5 times with 5�C7 animals per group. Differences were considered to be significant at a P value of [http://www.selleckchem.com/products/forskolin.html Forskolin cell line] were not sensitized with OVA but challenged with OVA aerosols (HDM/PBS_OVA) did not develop airway inflammation. Prior HDM-induced inflammation also increased production of Th2 cytokines IL-4, IL-5 and IL-13 compared with the two control groups. In HDM/PBS_OVA, some IL-5 and IL-13 was produced, while PBS/OVA_OVA mice did not produce any Th2 cytokines. IFN�� levels were not significantly different between groups (Fig.?1C). Histological analysis revealed significantly more mucus-producing goblet cells and peribronchial infiltrates compared with the two control groups (Fig.?1D,E). In concordance with the other inflammatory parameters, only HDM/OVA_OVA mice showed a significant increase in OVA-specific IgE and not the HDM/PBS_OVA or PBS/OVA_OVA mice (Fig?1F).
