Infection with NH/P68 caused a significant increase of IFN-β gene expression in moMΦ at different times pi; in particular, we observed up-regulation at 6 (p < 0.05), 9 (p < 0.05), 12 (p < 0.05), 21 (p < 0.001) hours post-infection with respect to time 0. This evidence concerns the gene IFNB1 and infection.
