Figure Lengend Snippet: FIGURE 6. Impact of β2-AR blockade on corneal inflammatory response. (A) Volcano plot depicting differentially expressed genes in dry eye mouse corneas with ICI 118,551 (ICI) or vehicle treatment (n = 4 per group). (B) Top 10 KEGG enrichment of downregulated genes in ICI versus vehicle-treated corneas. (C) Heatmap showing differentially expressed genes. (D) Comparison of Cxcl1, Cxcl2, IL17c, and S100a9 mRNA transcripts in mouse corneas (n = 5 per group). (E) CD45 staining of corneal cross-sections. Scale bar = 50 μm, n = 5 per group. (F) Nuclear translocation of NF-κB p65 in normal medium, 500 mOsM medium, and 500 mOsM medium supplemented with ICI. Scale bar = 20 μm. (G) The protein levels of p-NF-κB p65 (n = 5 per group). (H) Comparison of TNF-α, IL-1β, CXCL1, and CXCL2 mRNA transcripts in HCECs (n = 5 per group). Data are shown as mean ± SEM. *P < 0.05, **P < 0.01, ***P < 0.001, ns, not significant.
