Figure 10

Invaginated vesicles and the opposite endoplasmic reticulum (ER), the points where the vesicle touches the apposing membrane are seen as electron dense knobs. (A) shows one vesicle touching an ER ready to deliver its content to the neighboring ER. (B) shows two pairs of apposing vesicles, the lower vesicles deliver the contents to the apposing ER via the touching knobs; the right pair shows a newly budding virus in the upper ER. (C) shows a vesicle touching the lower ER containing few virions. (D) shows the point of attachment (circle) between a vesicle and ER with a presumed new virion (black arrow) in the lower chamber.
