Tetherin redistribution by HIV-1 and HIV-2 proviral clones. HeLa cells were either mock treated or transfected with 8 μg of HIV-1NL4-3 or HIV-2ROD10 proviral clones. Cells were fixed, permeabilized, and stained for endogenous tetherin (green), the TGN46 marker (blue), HIV-1 Vpu (red) or HIV-2 Env (red). Triple color merged images are shown. NL4-3 transfected cells showed tetherin co-localized with Vpu and the TGN. ROD10 transfected cells had two distinct appearances. ~25% of cells showed tetherin localized with a compact TGN marker (upper panels), while the majority of the cells had tetherin in a more diffuse perinuclear location that co-localized with more distorted TGN staining (lower panels). Scale bars represent 10 μM.
