Analysis of cellular protein expression in ZIKV-infected hBMECs. (A to C) hBMECs were mock infected or infected with ZIKV, and 1 to 9 dpi supernatants were analyzed in an ELISA (R&D Systems) for CCL/RANTES (A), IFN-β (B), and IFN-λ (C) levels relative to antigen standards. As an hBMEC IFN-β response control, we transfected hBMECs with poly(I/C) (1 µg/ml) and Fugene6 at 3:1 and evaluated secreted IFN-β levels in supernatants via ELISA (36 h posttransfection) (D) Western blot analysis of MXA and IFIT1 genes, and GAPDH controls, in lysates from mock-infected or ZIKV-infected hBMECs (1 to 9 dpi). IFIT and MxA protein levels in ZIKV-infected hBMECs 9 dpi versus results 6 h post-IFN-α treatment (1,000 U/ml).
