Figure: Weight loss of BALB/c mice was measured daily after intranasal inoculation with Mock, PR8 WT, or PR8
D101H virus (**p < 0.01; log rank).
Discussion: However, IAV-PR8 and IAV-PR8/
NS1 (
D101H) replicated to similar levels in lung tissues, indicating that such an effect on antiviral RNAi, if any, is undetectable in the mouse model.
