The levels of Zbp1 mRNA and protein did not change significantly on day 7 after infection, but significantly upregulated on both the 14 and 21 days after infection (Figure 4D,E), The apparent inconsistency between the trends in panels D and E on days 14 and 21 may be due to post‐translational modifications of Zbp1 or the post‐transcriptional regulation at 21 days post‐infection. This evidence concerns the gene ZBP1 and infection.
