Notably, myeloid cells in AG ferrets showed significantly elevated expression of inflammatory cytokines, including IL-1β, IL-10, IL-18, NFκB1, and S100A8, as well as upregulated IFNGR2 expression throughout infection, especially 4dpi (Figs 6C, 6D, S6D, and S6E). This evidence concerns the gene IL1B and infection.
