Of the 41 transcripts that were synergistically upregulated by the combination of LIGHT with IL-13 (Fig. 3), some, such as CCL2, CH25H, IL1RL1, EGR2, RGS4, and IL32, were strongly expressed in ILD fibroblast clusters 11 or 12, whereas others were randomly expressed in alternate clusters (Fig. S2A). The gene discussed is IL13; the disease is interstitial lung disease.
