It is noteworthy that whereas our data show a strong inhibition of IFIT-1 mRNA expression during Armenia/07 infection, in comparison with the expression during NH/P68 infection, the amount of IFN-β secreted after 8 hpi with Armenia/07 does not affect IFN-β-dependent gene IFIT-1 expression. The gene discussed is IFNB1; the disease is infection.
