    FIGURE 4 Allergic sensitization to BPE is independent of inflammasome-induced caspase 1 activation. (A) Immunofluorescence staining of lung sections from C57BL/6 and Nlrp3-/- mice (Figure 3) against ASC (red) and <t>CD45</t> (white). Dapi (blue) was used to stain cell nuclei. Scale bar is 20 µm. The dashed line marks the epithelial cell barrier. b= bronchiole. (B) Quantification of ASC+/CD45+ cells of 3 mice/group, 1 image/mouse as depicted in (A). (C) BPE-specific serum IgE was measured via antigen-induced cross-linking of Fcϵ-receptors on RBL-2H3 cells and subsequent degranulation and release of b-hexosaminidase (b-hex release). (D, E) Cytokines secreted into BALF (D) or by restimulated splenocytes (E) were measured by Multiplex technology. The data are presented as box plots of at least 5 mice per treatment group of 3 individual experiments. Each mouse is depicted as one data point. One-way ANOVA with Tukey’s post hoc test was performed to determine statistical significance. *p<0.05, **p<0.01.
