An innate protection against Ebola (IMAGE) University of Pennsylvania Caption An innate mechanism in human cells may prevent Ebola virus from spreading, according to new Penn Vet-led research. Using powerful confocal microscopy, they tracked the budding of virus-like particles from cells (shown in the filamentous projections in the cell in the upper right) and how autophagy, a “self-eating” cellular process, by which viral proteins are sequestered in vesicles (shown in the cell in the lower left), inhibits virus-like particles from exiting.
