gro29 cells accumulate virions in vesicles reminiscent of autophagosomes.

<p>At 18 h post infection, HSV-1 infected L (A) and gro29 (B) cells were harvested for electron microscopy. Representative electron micrographs are shown. Arrowheads indicate virions, while arrows identify cytoplasmic material within the vesicles. Inset in (A) shows a mature HSV-1 virion. Insets in (B) show a mature virion, an enveloped empty capsid and a non-enveloped nucleocapsid containing DNA (left to right).
