    Transcriptomic analysis of alveolar macrophages treated with combinations of recombinant IL-33, IL-13, and IL-17A in vitro . Macrophages were extracted from wild-type (WT) BALB/cJ mice as described in Methods and were plated in technical triplicate for whole transcriptomic sequencing. ( A ) Principal Component Analysis was used for assessing global, transcriptional changes induced by combinations of recombinant (r) IL-33, rIL-13, and rIL-17A in alveolar macrophages. ( B ) Volcano plot of differentially expressed genes between rIL-13-treated and control alveolar macrophages. Significance cut-offs for this analysis was designated to be p-value <.0001, fold change = +/- 1.5. Gene identifiers were manually annotated and therefore approximated. For volcano plots, the X-axis was transformed as a function of Log2[fold-change], whereas the Y-axis was generated by calculating -log10[p-value]. ( C ) Scatter plots designating expression levels of Il17ra and Il17rc in alveolar macrophages at baseline and post-cytokine stimulation (TPM-normalized). Bulk RNA sequencing of alveolar macrophages stimulated in vitro was performed only once.

    Extended transcriptional analysis of alveolar macrophages treated with combinations of recombinant IL-33, IL-13, and IL-17A relative to baseline. The algorithm DESeq2 was applied for identifying and ranking the significance of genes differentially expressed between macrophage treatment groups. DESeq2 computed an ANOVA table (fold-change, p-value, false-discovery rate step-up) for each comparison visualized here. Significantly up- or downregulated genes were illustrated by volcano plot once transformed as function of -log10[p-value] (Y-axis) and Log2[fold-change] (X-axis). Normalization of the data (median ratio) was also performed with DESeq2 by default. Significance cut-offs for this analysis was designated to be p-value <.0001, fold change = +/- 1.5. Gene identifiers in each visualization were manually annotated, and some lines are thus approximated due to size restraints and overlapping of datapoints.

    Significantly upregulated and downregulated gene expression in lung fibroblasts after rIL-33/rIL-13/rIL-17A treatment. Statistically significant (p<.0001), differential expression (fold change +/- 1.5) was noted initially for 1,642 genes (among the 18,079 detected by RNAseq) when comparing rIL- 33/13/17A-stimulated fibroblasts to untreated cells (refer to ). We extended our comparative analysis by identifying statistically significant, differentially expressed genes in rIL- 33/13/17A-stimulated fibroblasts relative to every group that received cytokine treatment during the assay ( i.e., vs. rIL-33/rIL-13, rIL-33/rIL-17A- and rIL-33-stimulated fibroblasts). From the original list of 1,642 genes (rIL-33/rIL-13/rIL-17A-stimulated fibroblasts vs. untreated), only 268 genes were statistically significant upon comparing rIL-33/rIL-13/rIL-17A cells to each remaining treatment group (false discovery rate <.01; 131 downregulated and 137 upregulated). Ultimately, we ranked gene expression in this filtered ANOVA table using the fold-change value derived from comparing rIL-33/rIL-13/rIL-17A-stimulated fibroblasts to untreated cells.
