Among the top 20 KEGG pathway enrichments influenced by DIV1 infection, half of them were found to be immune-related pathways, including the Toll and IMD signaling pathway, IL-17 signaling pathway, C-type lectin receptor signaling pathway, complement and coagulation cascades, antigen processing and presentation, necroptosis, apoptosis, NOD-like receptor signaling pathway, apoptosis—multiple species, and TNF signaling pathway. This evidence concerns the gene TLR4 and infection.
