Virus budding has been reported as a primary mechanism for the release of virus particles outside the cell for some viruses including human immunodeficiency virus hiv and an exocytic pathway in. Enveloped viruses escape infected cells by budding through limiting membranes.
In the inset this budding is topologically inverted from clathrin mediated endocytosis cme which forms a vesicle inside the cell.
Virus budding and the escrt pathway.
