How do viruses enter animal cells

WebJul 30, 2024 · Non-enveloped or “naked” animal viruses may enter cells in two different ways. As a protein in the viral capsid binds to its receptor on the host cell, the virus may be taken inside the cell via a vesicle during the normal cell process of … 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.
