KEGG enrichment analysis showed a Delta-specific downregulation of a small set of components of proinflammatory interleukin-17 (IL-17) and TNF signaling pathways and cytokine-cytokine interaction, late in infection (Fig. 5H, Fig. S3B), indicating that Delta not only spares cytokine induction, but inhibits it at the later stages of infection. Here, TNF is linked to infection.
