IFNA2 and infection: We also quantified in the hiPSC-derived trophoblasts the secreted levels of type I (IFNA2), type II (IFNG) and type III (IFNL1) IFNs produced by these cells in the absence of virus or after infection with ZIKVBR and culture for 48 h (Fig 3B, upper panel) or 96 h (Fig 3B, lower panel).
