These distinct forms of virus-induced structures include double-membrane vesicles (DMVs), found during viral infections as diverse and notorious as those of coronaviruses, enteroviruses, noroviruses, or hepatitis C virus.

Are vesicles single or double membrane?

Plus‐strand RNA viruses induce the formation of two types of vesicles: (i) single‐membrane vesicles, formed by negatively curved membranes and initiated by invaginations of the pre‐existing membrane bilayer, giving rise to spherules or vacuoles toward the lumen of the targeted cell organelle, and (ii) double‐membrane ...

Are vesicles double membrane?

Double-membraned vesicles are usually rare in cells, but DMVs are induced during autophagy. ... These vesicles closely resemble cellular organelles called omegasomes that are formed from the ER during the initial stages of autophagy [37], and mature into autophagosomes labelled with autophagy marker Atg8/LC3.
