WebDuring entry via endocytosis the virus enters the host cell within an endocytic vesicle. Non-enveloped viruses can only enter animal cells via endocytosis. During entry via membrane … WebAbstract. Enveloped animal viruses enter their host cells by a process of membrane fusion. This fusion can occur at the cell plasma membrane or within the endocytic vacuolar system, depending on the characteristics of the virus fusion protein. Examples of both pathways of viral entry are detailed in this review.
