This PDF file includes:

  • Methods
  • Fig. S1. ISG expression is elevated in Ifnar1+/− placentas and fetuses but not in Irf3−/−Irf7−/− after ZIKV infection.
  • Fig. S2. Ifnar1−/− placentas harbor more infectious ZIKV compared with Ifnar1+/− littermates.
  • Fig. S3. Global gene expression analysis reveals elevated ISG levels in infected Ifnar1+/− placentas.
  • Fig. S4. ZIKV infection of the maternal-fetal interface is restricted to the decidua.
  • Fig. S5. Placental architecture of Ifnar1+/− fetuses is normal at E9.5 but disrupted at E11.5 and E12.5.
  • Fig. S6. Labyrinth of Ifnar1+/− placenta exhibits decreased fetal endothelial cells.
  • Fig. S7. Ifnar1+/− but not Ifnar1−/− fetuses are resorbed after subcutaneous infection with Brazilian ZIKV.
  • Table S1. Primers for mouse qPCR.
  • Table S2. Top differentially regulated genes and pathways in ZIKV-infected Ifnar1+/− versus Ifnar1−/− placentas.
  • Legend for table S3
  • References (56—61)
