Key result

Viral strategies and cellular countermeasures compete to regulate mRNA access and control viral translation.

Key Points

This review summarizes the competing molecular mechanisms used by viruses to commandeer the host translation machinery and the cellular countermeasures mounted to suppress viral protein synthesis.
Synthesized molecular, genetic, and biochemical evidence detailing viral interaction with host translation apparatuses.
Evaluated mechanisms governing viral mRNA access to ribosomes, host defense responses, and viral counter-defenses.
Viruses utilize specialized mechanisms, such as internal ribosome entry sites and initiation factor modifications, to preferentially direct host ribosomes toward viral mRNAs.
Host cells deploy translational shutoff pathways and stress response granules to restrict viral spread, which viruses frequently overcome through tailored antagonist proteins.

Implication

Suggests novel antiviral targets at translation interface; leaves open relevance to virus-associated cardiovascular disease.

Abstract

Viruses depend on the cellular translation apparatus, and the translation process is consequently a focus for competing mechanisms to promote and to restrict viral translation [...]
