Anthrax Lethal Toxin is a classical AB-toxin comprised of two components, Protective Antigen (PA) and Lethal Factor (LF). Here we show that following assembly and endocytosis, PA forms a channel that translocates LF, not only into the cytosol, but also into the lumen of endosomal intraluminal vesicles (ILVs). These ILVs can fuse and release LF into the cytosol, where LF can proteolyze and disable host targets. We find that LF can persist in ILVs for days, fully sheltered from proteolytic degradation, both in vitro and in vivo. During this time ILV-localized LF can be transmitted to daughter cells upon cell division. In addition, LF-containing ILVs can be delivered to the extracellular medium as exosomes. These can deliver LF to the cytosol of naïve cells in a manner that is independent of the typical anthrax toxin-receptor trafficking pathway, while being sheltered from neutralizing extracellular factors of the immune system.
