AXL and infection: Blockingits kinase activity by the small-molecule inhibitor R428 (38, Figure 6 and Table 1) avoids viral entryand increases type 1 interferon (IFN-1) signaling.83 Similarly, the use of anti-Axl antibodies (Ab) completelyinhibited the entry of the dengue virus (DENV) in different cell lines.A549, Vero, Cos-7, and Huh7 5.1 cells showed high levels of Axl receptorand infection by DENV occurred rapidly.
