RIGI and infection: The items are associated with the infection of CDV, including the C-type lectin receptor signaling pathway, retinoic acid-inducible gene I (RIG-I)-like receptor signaling pathway, Janus kinase (JAK)-signal transducer and activator (STAT) signaling pathway, chemokine signaling pathway, toll-like receptor signaling pathway, interleukin 7 (IL-7) signaling pathway, nuclear factor (NF)-kappa B signaling pathway, nucleotide oligomerization domain (NOD)-like receptor signaling pathway, tumor necrosis factor (TNF) signaling pathway and cytokine-cytokine receptor interaction.
