Subcellular localization of nanoATV, HIV-1 and endolysosomal proteins. Cellular localization of Rab7 or LAMP1 endosomal compartments (red), HIV-1p24 (yellow) and nanoATV (green) are shown by confocal microscopy. Cell nuclei were stained with DAPI (blue). Merged images showed the co-localization of all proteins. Fluorescence images were acquired with a LSM 510 confocal microscopy, 400x magnification.
