The number of puncta quantified following WT/Env infection was similar to the number of background puncta in uninfected control cells (Fig 6A and 6B)
The number of puncta quantified following WT/Env infection was similar to the number of background puncta in uninfected control cells (Fig 6A and 6B). titers of VSVg pseudotyped R7EnvGFP and B-MLV pseudotyped. Cells were fixed 0, 1 and 3h (shown) post infection and stained for Nup358. (C) The fraction of Nup358 signal in the cytoplasm at the indicated time PI.20 or more cells were analyzed in each sample. Error bars represent the SEM of three independent experiments. (***p 0.001, *p 0.05, ns = not significant). Data is representative of three or more independent experiments.(TIF) ppat.1005700.s002.tif (763K) GUID:?619A7B0C-3D0C-4980-B70B-77D249ED7E97 S3 SERPINA3 Fig: HIV-1 infection does not induce any change in NUP153 localization.

HeLa cells transfected with a NUP358-GFP expressing BAF were synchronously infected with GIR labeled HIV-1 viral particles (MOI 0.3). 2 hours after infection, cells were imaged every 15 seconds for 10 minutes. Shown are individual z-planes showing a virus observed to traffic away from the nucleus and ultimately return to the area of the nuclear envelope during the acquisition period. The arrow in the first frame indicates the viral particle exhibiting the behavior described in the text.(MOV) ppat.1005700.s006.mov (39M) GUID:?68B48817-0DDA-4970-BF80-45570F06EC55 SL910102 S2 Movie: Anterograde trafficking of HIV-1 cores during infection.
