For TLR3, the expression level was downregulated at 6 and 24 h p.i. (0.85- and 0.75-fold, respectively) and upregulated at 36 h p.i. (1.46-fold) in response to SS-10 infection, whereas the expression level of TLR3 was upregulated at 6 h p.i. and downregulated at 24 and 36 h p.i. following infection with NH-10 or after stimulation with poly(I:C) (Fig. 2a). This evidence concerns the gene TLR3 and infection.
