Virus need the host cell ? its genes, proteins, and structures? for the replication and assembly of progeny virus, Thus, evolutionarily successful viruses have acquired genes and mechanisms that allow them to use the host cell’s assets, even as they trigger ER stress and the UPR, en route to apoptosis. Some of the genes acquired by viruses for controlling the cellular response to infection encode anti-apoptotic proteins, which temporarily counteract the action of pro-apoptotic factors that are produced by the host cell on viral infection. |
