WebOct 14, 2024 · Host Shut-Off . General host shut-off, that is viruses halting cellular protein expression, is an effective way to actively suppress all cellular innate immune responses against the virus, and simultaneously provide the virus with the full capacity of the cellular translation machinery for their own use. WebThe synthesis of host cell proteins is adversely inhibited in many virus infections, whereas viral proteins are efficiently synthesized. This phenomenon leads to the accumulation of viral proteins concurrently with a profound decline in global host protein synthesis, a phenomenon often termed “host shutoff”.
