  1. The dataset was interrogated for pathway enrichment or depletion using the canonical pathways from the MsigDb collection using Gene Set Enrichment Analysis (GSEA). The GSEA pathway analysis results show host gene enrichment involving inflammatory, immune and signaling activation, and host gene depletion involving wound repair. NES: normalized enrichment score; FWER: family-wise error rate. Values in log fold change (logFC) column indicate fold change ranked from highest to lowest (p < 0.05, FWER < 0.05).
