AXL and Zika virus infectious disease: Although in vitro AXL depletion or the use of anti-AXL antibodies rendered cells resistant to infection (Liu et al., 2016; Meertens et al., 2017), in vivo AXL (or members of the TAM family) knock-out in IFNAR−/− mice had no significant effect on these mice susceptibility to ZIKV infection (Hastings et al., 2017; Wang et al., 2017).
