F. HEK293T cells were transfected with plasmids encoding individual ZIKV proteins, the indicated promoter-driven firefly luciferase plasmids and a constitutively active renilla luciferase construct (pRL-TK), as well as 0.4 μg of poly(I:C). Twenty-four hours later cell lysates were harvested and subjected to luciferase assay. C = capsid; E = envelope. Values are expressed as mean ± standard error. *P<0.05, **P<0.01 (Student's t-test); N=3
