The inhibitory effect of IFITM1 and mutants of IFITM1 on DENV replication. pcDNA3.1, pcDNA3.1-Flag-IFITM1 and mutants of pcDNA3.1-Flag-IFITM1 were transfected in Vero cells, respectively. After 24 h, cells were infected with DENV (MOI = 0.1). After 48 h, cells were collected, and the expression level of DENV E protein was analyzed by Western blotting .

HEK293T cells were mock-infected or infected with DENV 2 or DENV 4 and at 0, 20, 30 min and 1 hr p.i., cells were incubated with pan specific anti-dengue E protein antibody followed by an appropriate secondary antibody (green), phalloidin-TRITC (red) and DAPI (blue). Cells were observed under an Olympus Fluo View 1000 confocal microscope. Only the actin channel is shown. Full merged images with signal from all three channels are shown in Fig E in S1 File .
