NF‐κB 52 was significantly upregulated in spleen at 24 hpi and in Harderian glands at both time points, and NF‐κB 65 was significantly upregulated in bone marrow at 48 hpi (p < 0.05) in response to GD infection, while none of the isoforms were significantly affected by F48E9 infection (Supporting Information Figure S2). This evidence concerns the gene NFKB1 and infection.
