Figure 4From: HIV-1 Vpu and HIV-2 Env counteract BST-2/tetherin by sequestration in a perinuclear compartmentCo-staining of tetherin with calnexin and endocytosed transferrin. HeLa cells transfected with either 2 μg of Vpu (Vphu-HcRed) or ROD10 Env plasmids were analyzed for co-localization with the ER marker, calnexin (A), or with endocytosed transferrin (B). Triple color merged images are shown. Scale bars represent 10 μM.Back to article page
