Fold changes are presented as log 2 transformations. Red dots represent DEGs upregulated in the Co7 group. B) Protein‐protein interaction (PPI) network analysis of differentially expressed genes (DEGs) in the Co7‐treated group compared to the DMSO group, revealing significant enrichment in pathways associated with the innate immune response and type I interferon signaling.

F) Volcano plot representing the differential gene expression analysis between Co7‐ and LPS‐treated RAW 264.7 cells after 3 h of treatment. Fold changes are displayed as log 2 transformations. Red dots indicate genes upregulated in the Co7 group, while blue dots represent downregulated genes compared to LPS treatment.

H) Co7 significantly reduced the mortality rate in mice (n = 10 per group) following LPS challenge (20 mg/kg), compared to the PBS control group. RT‐qPCR data were presented as means ± SEM from three independent experiments. Statistical significance was determined using one‐way ANOVA with Bonferroni's multiple comparisons test (left three panels in E), paired‐samples t‐test (D, right panel of EMCV and HSV in E), or the log‐rank test (H). * P < 0.05, ** P < 0.01, and *** P < 0.001.
