FMR1 and infection: We observed that Δ10 ZIKV infection rate in HeLa cells is reduced compared to WT ZIKV under negative control conditions (~11% vs~25% infected cells) and, importantly, FMRP KD disproportionately enhanced Δ10 ZIKV infection rate (Figure 5C): whereas WT virus was enhanced by approximately 3-fold, the infection rate for Δ10 ZIKV rose by nearly 5-fold (Figure 5D).
