Activation of ifn mediated by CcTlr19.A Luci-ifn and nf-kb reporter plasmids, rhRL-TK and CcTlr19-FUGW expression vector or an empty vector (control) were transfected into 293 T cells. After 48 h, Firefly and Renilla luciferase activities were detected, and the ratio was calculated. Means ± SD (n = 4), *P < 0.05, ***P < 0.001, ****P < 0.0001, t test. B–D 293 T cells were transfected targeted plasmid. After 36 h, the cells were stimulated with poly(I:C), PGN and LPS for the indicated periods of time. Firefly and Renilla luciferase activities were detected, and the ratio was calculated. Means ± SD (n = 4), *P < 0.05, ***P < 0.001, ****P < 0.0001, two-way ANOVA.
