In Ifnar1 KO cultures, ZIKV was observed to varying extents in all major cell types with the possible exception of neurones which occasionally appeared positive even in mock-infected cultures (Fig. 2a-e illustrates infected cells following ZIKV infection at MOI 0.3 or 3.0 for 24 or 72 hpi, respectively). This evidence concerns the gene IFNAR1 and Zika virus infectious disease.
